INSERT ... ON DUPLICATE KEY UPDATE Statement","text":"If you specify an ON DUPLICATE KEY UPDATE clause and a row to be inserted would cause a duplicate value in a UNIQUE index or PRIMARY KEY, an UPDATE of the old row occurs.
INSERT\n [INTO] tbl_name\n [(col_name [, col_name] ...)]\n { {VALUES | VALUE} (value_list) [, (value_list)] ... }\n [AS row_alias[(col_alias [, col_alias] ...)]]\n [ON DUPLICATE KEY UPDATE assignment_list]\n\nassignment:\n col_name = \n value\n | [row_alias.]col_name\n | [tbl_name.]col_name\n | [row_alias.]col_alias\n\nassignment_list:\n assignment [, assignment] ...\nFor example, if column a is declared as UNIQUE and contains the value 1, the following two statements have similar effect:
INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n ON DUPLICATE KEY UPDATE c=c+1;\n\nUPDATE t1 SET c=c+1 WHERE a=1;\nIf column b is also unique, the INSERT is equivalent to this UPDATE statement instead:
UPDATE t1 SET c=c+1 WHERE a=1 OR b=2 LIMIT 1;\nIn assignment value expressions in the ON DUPLICATE KEY UPDATE clause, you can use the VALUES(col_name) function to refer to column values from the INSERT portion of the INSERT ... ON DUPLICATE KEY UPDATE statement. In other words, VALUES(col_name) in the ON DUPLICATE KEY UPDATE clause refers to the value of col_name that would be inserted, had no duplicate-key conflict occurred. This function is especially useful in multiple-row inserts. The VALUES() function is meaningful only in the ON DUPLICATE KEY UPDATE clause or INSERT statements and returns NULL otherwise. Example:
INSERT INTO t1 (a,b,c) VALUES (1,2,3),(4,5,6)\n ON DUPLICATE KEY UPDATE c=VALUES(a)+VALUES(b);\nThat statement is identical to the following two statements:
INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n ON DUPLICATE KEY UPDATE c=3;\nINSERT INTO t1 (a,b,c) VALUES (4,5,6)\n ON DUPLICATE KEY UPDATE c=9;\nIf the result of INSERT ... ON DUPLICATE KEY UPDATE is incorrect such as the following example, there should be notified error messages to users and this statement failed.
INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n ON DUPLICATE KEY UPDATE c='a';\nREPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted.
REPLACE \n INTO tbl_name\n [(col_name [, col_name] ...)]\n { {VALUES | VALUE} (value_list) [, (value_list)] ...\n |\n VALUES row_constructor_list\n }\nExample:
CREATE TABLE test (\n id INT UNSIGNED NOT NULL AUTO_INCREMENT,\n data VARCHAR(64) DEFAULT NULL,\n ts TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,\n PRIMARY KEY (id)\n);\nWhen we create this table and run the statements shown in the mysql client, the result is as follows:
mysql> REPLACE INTO test VALUES (1, 'Old', '2014-08-20 18:47:00');\nQuery OK, 1 row affected (0.04 sec)\n\nmysql> REPLACE INTO test VALUES (1, 'New', '2014-08-20 18:47:42');\nQuery OK, 2 rows affected (0.04 sec)\n\nmysql> SELECT * FROM test;\n+----+------+---------------------+\n| id | data | ts |\n+----+------+---------------------+\n| 1 | New | 2014-08-20 18:47:42 |\n+----+------+---------------------+\n1 row in set (0.00 sec)\nNow we create a second table almost identical to the first, except that the primary key now covers 2 columns, as shown here (emphasized text):
CREATE TABLE test2 (\n id INT UNSIGNED NOT NULL AUTO_INCREMENT,\n data VARCHAR(64) DEFAULT NULL,\n ts TIMESTAMP NOT NULL,\n PRIMARY KEY (id, ts)\n);\nWhen we run on test2 the same two REPLACE statements as we did on the original test table, we obtain a different result:
mysql> REPLACE INTO test2 VALUES (1, 'Old', '2014-08-20 18:47:00');\nQuery OK, 1 row affected (0.05 sec)\n\nmysql> REPLACE INTO test2 VALUES (1, 'New', '2014-08-20 18:47:42');\nQuery OK, 1 row affected (0.06 sec)\n\nmysql> SELECT * FROM test2;\n+----+------+---------------------+\n| id | data | ts |\n+----+------+---------------------+\n| 1 | Old | 2014-08-20 18:47:00 |\n| 1 | New | 2014-08-20 18:47:42 |\n+----+------+---------------------+\n2 rows in set (0.00 sec)\nVALUES is a DML statement which returns a set of one or more rows as a table. In other words, it is a table value constructor which also functions as a standalone SQL statement.
VALUES row_constructor_list [ORDER BY column_designator] [LIMIT number]\n\nrow_constructor_list:\n ROW(value_list)[, ROW(value_list)][, ...]\n\nvalue_list:\n value[, value][, ...]\n\ncolumn_designator:\n column_index\nThe VALUES statement consists of the VALUES keyword followed by a list of one or more row constructors, separated by commas. A row constructor consists of the ROW() row constructor clause with a value list of one or more scalar values enclosed in the parentheses. A value can be a literal of any MatrixOne data type or an expression that resolves to a scalar value. ROW() cannot be empty (but each of the supplied scalar values can be NULL). Each ROW() in the same VALUES statement must have the same number of values in its value list. The DEFAULT keyword is not supported by VALUES and causes a syntax error, except when it is used to supply values in an INSERT statement. The output of VALUES is a table:
mysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8);\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n| 1 | -2 | 3 |\n| 5 | 7 | 9 |\n| 4 | 6 | 8 |\n+----------+----------+----------+\n3 rows in set (0.00 sec)\nThe columns of the table output from VALUES have the implicitly named columns column_0, column_1, column_2, and so on, always beginning with 0. This fact can be used to order the rows by column using an optional ORDER BY clause in the same way that this clause works with a SELECT statement, as shown here:
mysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8) ORDER BY column_1;\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n| 1 | -2 | 3 |\n| 4 | 6 | 8 |\n| 5 | 7 | 9 |\n+----------+----------+----------+\n3 rows in set (0.00 sec)\n\nmysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8) ORDER BY column_1 limit 1;\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n| 1 | -2 | 3 |\n+----------+----------+----------+\n1 row in set (0.00 sec)\nThe VALUES statement is permissive regarding data types of column values; you can mix types within the same column, as shown here:
mysql> VALUES ROW(\"q\", 42, '2019-12-18'),\n -> ROW(23, \"abc\", 98.6),\n -> ROW(27.0002, \"Mary Smith\", '{\"a\": 10, \"b\": 25}');\n+----------+------------+--------------------+\n| column_0 | column_1 | column_2 |\n+----------+------------+--------------------+\n| q | 42 | 2019-12-18 |\n| 23 | abc | 98.6 |\n| 27.0002 | Mary Smith | {\"a\": 10, \"b\": 25} |\n+----------+------------+--------------------+\n3 rows in set (0.00 sec)\nWith UNION, as shown here:
mysql> VALUES ROW(1,2), ROW(3,4), ROW(5,6)\n > UNION VALUES ROW(10,15),ROW(20,25);\n+----------+----------+\n| column_0 | column_1 |\n+----------+----------+\n| 1 | 2 |\n| 3 | 4 |\n| 5 | 6 |\n| 10 | 15 |\n| 20 | 25 |\n+----------+----------+\n5 rows in set (0.00 sec)\nDO executes the expressions but does not return any results. In most respects, DO is shorthand for SELECT expr, ..., but has the advantage that it is slightly faster when you do not care about the result.
DO expr [, expr] ...\nDO is useful primarily with functions that have side effects, such as RELEASE_LOCK(). Example: This SELECT statement pauses, but also produces a result set:
mysql> SELECT SLEEP(5);\n+----------+\n| SLEEP(5) |\n+----------+\n| 0 |\n+----------+\n1 row in set (5.02 sec)\nDO, on the other hand, pauses without producing a result set.
mysql> DO SLEEP(5);\nQuery OK, 0 rows affected (4.99 sec)\nDECLARE statement declares local variables within stored programs. To provide a default value for a variable, include a DEFAULT clause. The value can be specified as an expression; it need not be a constant. If the DEFAULT clause is missing, the initial value is NULL.
DECLARE Statement\nDECLARE var_name [, var_name] ... type [DEFAULT value]\nThe HANDLER statement provides direct access to table storage engine interfaces.
HANDLER tbl_name OPEN [ [AS] alias]\nHANDLER tbl_name READ { FIRST | NEXT }\n [ WHERE where_condition ] [LIMIT ... ]\nHANDLER tbl_name CLOSE\nThe HANDLER ... OPEN statement opens a table, making it accessible using subsequent HANDLER ... READ statements. This table object is not shared by other sessions and is not closed until the session calls HANDLER ... CLOSE or the session terminates. The HANDLER ... READ syntax fetches a row from the table in natural row order that matches the WHERE condition. Natural row order is the order in which rows are stored in a TAE table data file. Without a LIMIT clause, all forms of HANDLER ... READ fetch a single row if one is available. To return a specific number of rows, include a LIMIT clause. It has the same syntax as for the SELECT statement. HANDLER ... CLOSE closes a table that was opened with HANDLER ... OPEN. Example:
mysql> create table t1(a int ,b int);\nQuery OK, 0 rows affected (0.01 sec)\nmysql> insert into t1 values(1,-1),(2,-2),(3,-3),(4,-4),(5,-5);\nQuery OK, 5 rows affected (0.04 sec)\nRecords: 5 Duplicates: 0 Warnings: 0\nmysql> handler t1 open as th;\nQuery OK, 0 rows affected (0.00 sec)\nmysql> handler th read first;\n+------+------+\n| a | b |\n+------+------+\n| 1 | -1 |\n+------+------+\n1 row in set (0.00 sec)\nmysql> handler th read first limit 3;\n+------+------+\n| a | b |\n+------+------+\n| 1 | -1 |\n| 2 | -2 |\n| 3 | -3 |\n+------+------+\n3 rows in set (0.00 sec)\nmysql> handler th read next;\n+------+------+\n| a | b |\n+------+------+\n| 5 | -5 |\n+------+------+\n2 rows in set (0.00 sec)\nmysql> handler th read next limit 3;\n+------+------+\n| a | b |\n+------+------+\n| 5 | -5 |\n+------+------+\n2 rows in set (0.00 sec)\nmysql> handler th close;\nQuery OK, 0 rows affected (0.00 sec)\nUse CREATE TABLE ... LIKE to create an empty table based on the definition of another table, including any column attributes and indexes defined in the original table:
CREATE TABLE new_tbl LIKE orig_tbl;\nThe copy is created using the same version of the table storage format as the original table.
create table test1(a int, b float);\ncreate table test2 like test1;\nshow columns from test2;\n+-------+-------+------+------+---------+---------+\n| Field | Type | Null | Key | Default | Comment |\n+-------+-------+------+------+---------+---------+\n| a | INT | YES | | NULL | |\n| b | FLOAT | YES | | NULL | |\n+-------+-------+------+------+---------+---------+\n2 rows in set (0.11 sec)\nYou can create one table from another by adding a SELECT statement at the end of the CREATE TABLE statement:
CREATE TABLE new_tbl [AS] SELECT * FROM orig_tbl;\nCreate new columns for all elements in the SELECT. For example:
mysql> CREATE TABLE test (a INT NOT NULL AUTO_INCREMENT,\n -> PRIMARY KEY (a), KEY(b))\n -> SELECT b,c FROM test2;\nThis creates a table with three columns, a, b, and c. Notice that the columns from the SELECT statement are appended to the right side of the table, not overlapped onto it. Take the following example:
mysql> SELECT * FROM foo;\n+---+\n| n |\n+---+\n| 1 |\n+---+\n1 row in set (0.00 sec)\n\nmysql> CREATE TABLE bar (m INT) SELECT n FROM foo;\nQuery OK, 1 row affected (0.02 sec)\nRecords: 1 Duplicates: 0 Warnings: 0\n\nmysql> SELECT * FROM bar;\n+------+---+\n| m | n |\n+------+---+\n| NULL | 1 |\n+------+---+\n1 row in set (0.00 sec)\nThis statement creates a new trigger. A trigger is a named database object that is associated with a table, and that activates when a particular event occurs for the table. The trigger becomes associated with the table named tbl_name, which must refer to a permanent table.
CREATE\n [DEFINER = user]\n TRIGGER [IF NOT EXISTS] trigger_name\n trigger_time trigger_event\n ON tbl_name FOR EACH ROW\n [trigger_order]\n trigger_body\n\ntrigger_time: { BEFORE | AFTER }\n\ntrigger_event: { INSERT | UPDATE | DELETE }\n\ntrigger_order: { FOLLOWS | PRECEDES } other_trigger_name\nIF NOT EXISTS prevents an error from occurring if a trigger having the same name, on the same table, exists in the same schema.
trigger_time is the trigger action time. It can be BEFORE or AFTER to indicate that the trigger activates before or after each row to be modified.
trigger_event indicates the kind of operation that activates the trigger. These trigger_event values are permitted: INSERT: The trigger activates whenever a new row is inserted into the table (for example, through INSERT, LOAD DATA, and REPLACE statements). UPDATE: The trigger activates whenever a row is modified (for example, through UPDATE statements). DELETE: The trigger activates whenever a row is deleted from the table (for example, through DELETE and REPLACE statements). DROP TABLE and TRUNCATE TABLE statements on the table do not activate this trigger, because they do not use DELETE. Dropping a partition does not activate DELETE triggers, either. The trigger_event does not represent a literal type of SQL statement that activates the trigger so much as it represents a type of table operation. For example, an INSERT trigger activates not only for INSERT statements but also LOAD DATA statements because both statements insert rows into a table. trigger_body is the statement to execute when the trigger activates. To execute multiple statements, use the BEGIN ... END compound statement construct.
DROP TRIGGER [IF EXISTS] [schema_name.]trigger_name\nThis statement drops a trigger. The schema (database) name is optional. If the schema is omitted, the trigger is dropped from the default schema.
"},{"location":"MatrixOne/parser_camp_event/#8-truncate-table-and-kill-statement","title":"8. TRUNCATE TABLE and KILL Statement","text":"TRUNCATE TABLE Statement
TRUNCATE [TABLE] tbl_name\nTRUNCATE TABLE empties a table completely. Logically, TRUNCATE TABLE is similar to a DELETE statement that deletes all rows, or a sequence of DROP TABLE and CREATE TABLE statements.
KILL Statement
KILL [CONNECTION | QUERY] processlist_id\nEach connection to mysqld runs in a separate thread. You can kill a thread with the KILL processlist_id statement.

See config/kraft/README.md for details.\n#\n\n############################# Server Basics #############################\n\n# The role of this server. Setting this puts us in KRaft mode\nprocess.roles=broker,controller\n\n# The node id associated with this instance's roles\nnode.id=1\n\n# The connect string for the controller quorum\ncontroller.quorum.voters=1@192.168.146.12:9093\n\n############################# Socket Server Settings #############################\n\n# The address the socket server listens on.\n# Combined nodes (i.e. those with `process.roles=broker,controller`) must list the controller listener here at a minimum.\n# If the broker listener is not defined, the default listener will use a host name that is equal to the value of java.net.InetAddress.getCanonicalHostName(),\n# with PLAINTEXT listener name, and port 9092.\n# FORMAT:\n# listeners = listener_name://host_name:port\n# EXAMPLE:\n# listeners = PLAINTEXT://your.host.name:9092\n#listeners=PLAINTEXT://:9092,CONTROLLER://:9093\nlisteners=PLAINTEXT://192.168.146.12:9092,CONTROLLER://192.168.146.12:9093\n\n# Name of listener used for communication between brokers.\ninter.broker.listener.name=PLAINTEXT\n\n# Listener name, hostname and port the broker will advertise to clients.\n# If not set, it uses the value for \"listeners\".\n#advertised.listeners=PLAINTEXT://localhost:9092\n\n# A comma-separated list of the names of the listeners used by the controller.\n# If no explicit mapping set in `listener.security.protocol.map`, default will be using PLAINTEXT protocol\n# This is required if running in KRaft mode.\ncontroller.listener.names=CONTROLLER\n\n# Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details\nlistener.security.protocol.map=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL\n\n# The number of threads that the server uses for receiving requests from the network and sending responses to the network\nnum.network.threads=3\n\n# The number of threads that the server uses for processing requests, which may include disk I/O\nnum.io.threads=8\n\n# The send buffer (SO_SNDBUF) used by the socket server\nsocket.send.buffer.bytes=102400\n\n# The receive buffer (SO_RCVBUF) used by the socket server\nsocket.receive.buffer.bytes=102400\n\n# The maximum size of a request that the socket server will accept (protection against OOM)\nsocket.request.max.bytes=104857600\n\n\n############################# Log Basics #############################\n\n# A comma separated list of directories under which to store log files\nlog.dirs=/home/software/kafka_2.13-3.5.0/kraft-combined-logs\n\n# The default number of log partitions per topic. More partitions allow greater\n# parallelism for consumption, but this will also result in more files across\n# the brokers.\nnum.partitions=1\n\n# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.\n# This value is recommended to be increased for installations with data dirs located in RAID array.\nnum.recovery.threads.per.data.dir=1\n\n############################# Internal Topic Settings #############################\n# The replication factor for the group metadata internal topics \"__consumer_offsets\" and \"__transaction_state\"\n# For anything other than development testing, a value greater than 1 is recommended to ensure availability such as 3.\noffsets.topic.replication.factor=1\ntransaction.state.log.replication.factor=1\ntransaction.state.log.min.isr=1\n\n############################# Log Flush Policy #############################\n\n# Messages are immediately written to the filesystem but by default we only fsync() to sync\n# the OS cache lazily. The following configurations control the flush of data to disk.\n# There are a few important trade-offs here:\n# 1. Durability: Unflushed data may be lost if you are not using replication.\n# 2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.\n# 3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.\n# The settings below allow one to configure the flush policy to flush data after a period of time or\n# every N messages (or both). This can be done globally and overridden on a per-topic basis.\n\n# The number of messages to accept before forcing a flush of data to disk\n#log.flush.interval.messages=10000\n\n# The maximum amount of time a message can sit in a log before we force a flush\n#log.flush.interval.ms=1000\n\n############################# Log Retention Policy #############################\n\n# The following configurations control the disposal of log segments. The policy can\n# be set to delete segments after a period of time, or after a given size has accumulated.\n# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens\n# from the end of the log.\n\n# The minimum age of a log file to be eligible for deletion due to age\nlog.retention.hours=72\n\n# A size-based retention policy for logs. Segments are pruned from the log unless the remaining\n# segments drop below log.retention.bytes. Functions independently of log.retention.hours.\n#log.retention.bytes=1073741824\n\n# The maximum size of a log segment file. When this size is reached a new log segment will be created.\nlog.segment.bytes=1073741824\n\n# The interval at which log segments are checked to see if they can be deleted according\n# to the retention policies\nlog.retention.check.interval.ms=300000\n\u6587\u4ef6\u914d\u7f6e\u5b8c\u6210\u540e\uff0c\u6267\u884c\u5982\u4e0b\u547d\u4ee4\uff0c\u542f\u52a8 Kafka \u670d\u52a1\uff1a

INSERT ... ON DUPLICATE KEY UPDATE Statement","text":"If you specify an ON DUPLICATE KEY UPDATE clause and a row to be inserted would cause a duplicate value in a UNIQUE index or PRIMARY KEY, an UPDATE of the old row occurs.
INSERT\n [INTO] tbl_name\n [(col_name [, col_name] ...)]\n { {VALUES | VALUE} (value_list) [, (value_list)] ... }\n [AS row_alias[(col_alias [, col_alias] ...)]]\n [ON DUPLICATE KEY UPDATE assignment_list]\n\nassignment:\n col_name = \n value\n | [row_alias.]col_name\n | [tbl_name.]col_name\n | [row_alias.]col_alias\n\nassignment_list:\n assignment [, assignment] ...\nFor example, if column a is declared as UNIQUE and contains the value 1, the following two statements have similar effect:
INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n ON DUPLICATE KEY UPDATE c=c+1;\n\nUPDATE t1 SET c=c+1 WHERE a=1;\nIf column b is also unique, the INSERT is equivalent to this UPDATE statement instead:
UPDATE t1 SET c=c+1 WHERE a=1 OR b=2 LIMIT 1;\nIn assignment value expressions in the ON DUPLICATE KEY UPDATE clause, you can use the VALUES(col_name) function to refer to column values from the INSERT portion of the INSERT ... ON DUPLICATE KEY UPDATE statement. In other words, VALUES(col_name) in the ON DUPLICATE KEY UPDATE clause refers to the value of col_name that would be inserted, had no duplicate-key conflict occurred. This function is especially useful in multiple-row inserts. The VALUES() function is meaningful only in the ON DUPLICATE KEY UPDATE clause or INSERT statements and returns NULL otherwise. Example:
INSERT INTO t1 (a,b,c) VALUES (1,2,3),(4,5,6)\n ON DUPLICATE KEY UPDATE c=VALUES(a)+VALUES(b);\nThat statement is identical to the following two statements:
INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n ON DUPLICATE KEY UPDATE c=3;\nINSERT INTO t1 (a,b,c) VALUES (4,5,6)\n ON DUPLICATE KEY UPDATE c=9;\nIf the result of INSERT ... ON DUPLICATE KEY UPDATE is incorrect such as the following example, there should be notified error messages to users and this statement failed.
INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n ON DUPLICATE KEY UPDATE c='a';\nREPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted.
REPLACE \n INTO tbl_name\n [(col_name [, col_name] ...)]\n { {VALUES | VALUE} (value_list) [, (value_list)] ...\n |\n VALUES row_constructor_list\n }\nExample:
CREATE TABLE test (\n id INT UNSIGNED NOT NULL AUTO_INCREMENT,\n data VARCHAR(64) DEFAULT NULL,\n ts TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,\n PRIMARY KEY (id)\n);\nWhen we create this table and run the statements shown in the mysql client, the result is as follows:
mysql> REPLACE INTO test VALUES (1, 'Old', '2014-08-20 18:47:00');\nQuery OK, 1 row affected (0.04 sec)\n\nmysql> REPLACE INTO test VALUES (1, 'New', '2014-08-20 18:47:42');\nQuery OK, 2 rows affected (0.04 sec)\n\nmysql> SELECT * FROM test;\n+----+------+---------------------+\n| id | data | ts |\n+----+------+---------------------+\n| 1 | New | 2014-08-20 18:47:42 |\n+----+------+---------------------+\n1 row in set (0.00 sec)\nNow we create a second table almost identical to the first, except that the primary key now covers 2 columns, as shown here (emphasized text):
CREATE TABLE test2 (\n id INT UNSIGNED NOT NULL AUTO_INCREMENT,\n data VARCHAR(64) DEFAULT NULL,\n ts TIMESTAMP NOT NULL,\n PRIMARY KEY (id, ts)\n);\nWhen we run on test2 the same two REPLACE statements as we did on the original test table, we obtain a different result:
mysql> REPLACE INTO test2 VALUES (1, 'Old', '2014-08-20 18:47:00');\nQuery OK, 1 row affected (0.05 sec)\n\nmysql> REPLACE INTO test2 VALUES (1, 'New', '2014-08-20 18:47:42');\nQuery OK, 1 row affected (0.06 sec)\n\nmysql> SELECT * FROM test2;\n+----+------+---------------------+\n| id | data | ts |\n+----+------+---------------------+\n| 1 | Old | 2014-08-20 18:47:00 |\n| 1 | New | 2014-08-20 18:47:42 |\n+----+------+---------------------+\n2 rows in set (0.00 sec)\nVALUES is a DML statement which returns a set of one or more rows as a table. In other words, it is a table value constructor which also functions as a standalone SQL statement.
VALUES row_constructor_list [ORDER BY column_designator] [LIMIT number]\n\nrow_constructor_list:\n ROW(value_list)[, ROW(value_list)][, ...]\n\nvalue_list:\n value[, value][, ...]\n\ncolumn_designator:\n column_index\nThe VALUES statement consists of the VALUES keyword followed by a list of one or more row constructors, separated by commas. A row constructor consists of the ROW() row constructor clause with a value list of one or more scalar values enclosed in the parentheses. A value can be a literal of any MatrixOne data type or an expression that resolves to a scalar value. ROW() cannot be empty (but each of the supplied scalar values can be NULL). Each ROW() in the same VALUES statement must have the same number of values in its value list. The DEFAULT keyword is not supported by VALUES and causes a syntax error, except when it is used to supply values in an INSERT statement. The output of VALUES is a table:
mysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8);\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n| 1 | -2 | 3 |\n| 5 | 7 | 9 |\n| 4 | 6 | 8 |\n+----------+----------+----------+\n3 rows in set (0.00 sec)\nThe columns of the table output from VALUES have the implicitly named columns column_0, column_1, column_2, and so on, always beginning with 0. This fact can be used to order the rows by column using an optional ORDER BY clause in the same way that this clause works with a SELECT statement, as shown here:
mysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8) ORDER BY column_1;\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n| 1 | -2 | 3 |\n| 4 | 6 | 8 |\n| 5 | 7 | 9 |\n+----------+----------+----------+\n3 rows in set (0.00 sec)\n\nmysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8) ORDER BY column_1 limit 1;\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n| 1 | -2 | 3 |\n+----------+----------+----------+\n1 row in set (0.00 sec)\nThe VALUES statement is permissive regarding data types of column values; you can mix types within the same column, as shown here:
mysql> VALUES ROW(\"q\", 42, '2019-12-18'),\n -> ROW(23, \"abc\", 98.6),\n -> ROW(27.0002, \"Mary Smith\", '{\"a\": 10, \"b\": 25}');\n+----------+------------+--------------------+\n| column_0 | column_1 | column_2 |\n+----------+------------+--------------------+\n| q | 42 | 2019-12-18 |\n| 23 | abc | 98.6 |\n| 27.0002 | Mary Smith | {\"a\": 10, \"b\": 25} |\n+----------+------------+--------------------+\n3 rows in set (0.00 sec)\nWith UNION, as shown here:
mysql> VALUES ROW(1,2), ROW(3,4), ROW(5,6)\n > UNION VALUES ROW(10,15),ROW(20,25);\n+----------+----------+\n| column_0 | column_1 |\n+----------+----------+\n| 1 | 2 |\n| 3 | 4 |\n| 5 | 6 |\n| 10 | 15 |\n| 20 | 25 |\n+----------+----------+\n5 rows in set (0.00 sec)\nDO executes the expressions but does not return any results. In most respects, DO is shorthand for SELECT expr, ..., but has the advantage that it is slightly faster when you do not care about the result.
DO expr [, expr] ...\nDO is useful primarily with functions that have side effects, such as RELEASE_LOCK(). Example: This SELECT statement pauses, but also produces a result set:
mysql> SELECT SLEEP(5);\n+----------+\n| SLEEP(5) |\n+----------+\n| 0 |\n+----------+\n1 row in set (5.02 sec)\nDO, on the other hand, pauses without producing a result set.
mysql> DO SLEEP(5);\nQuery OK, 0 rows affected (4.99 sec)\nDECLARE statement declares local variables within stored programs. To provide a default value for a variable, include a DEFAULT clause. The value can be specified as an expression; it need not be a constant. If the DEFAULT clause is missing, the initial value is NULL.
DECLARE Statement\nDECLARE var_name [, var_name] ... type [DEFAULT value]\nThe HANDLER statement provides direct access to table storage engine interfaces.
HANDLER tbl_name OPEN [ [AS] alias]\nHANDLER tbl_name READ { FIRST | NEXT }\n [ WHERE where_condition ] [LIMIT ... ]\nHANDLER tbl_name CLOSE\nThe HANDLER ... OPEN statement opens a table, making it accessible using subsequent HANDLER ... READ statements. This table object is not shared by other sessions and is not closed until the session calls HANDLER ... CLOSE or the session terminates. The HANDLER ... READ syntax fetches a row from the table in natural row order that matches the WHERE condition. Natural row order is the order in which rows are stored in a TAE table data file. Without a LIMIT clause, all forms of HANDLER ... READ fetch a single row if one is available. To return a specific number of rows, include a LIMIT clause. It has the same syntax as for the SELECT statement. HANDLER ... CLOSE closes a table that was opened with HANDLER ... OPEN. Example:
mysql> create table t1(a int ,b int);\nQuery OK, 0 rows affected (0.01 sec)\nmysql> insert into t1 values(1,-1),(2,-2),(3,-3),(4,-4),(5,-5);\nQuery OK, 5 rows affected (0.04 sec)\nRecords: 5 Duplicates: 0 Warnings: 0\nmysql> handler t1 open as th;\nQuery OK, 0 rows affected (0.00 sec)\nmysql> handler th read first;\n+------+------+\n| a | b |\n+------+------+\n| 1 | -1 |\n+------+------+\n1 row in set (0.00 sec)\nmysql> handler th read first limit 3;\n+------+------+\n| a | b |\n+------+------+\n| 1 | -1 |\n| 2 | -2 |\n| 3 | -3 |\n+------+------+\n3 rows in set (0.00 sec)\nmysql> handler th read next;\n+------+------+\n| a | b |\n+------+------+\n| 5 | -5 |\n+------+------+\n2 rows in set (0.00 sec)\nmysql> handler th read next limit 3;\n+------+------+\n| a | b |\n+------+------+\n| 5 | -5 |\n+------+------+\n2 rows in set (0.00 sec)\nmysql> handler th close;\nQuery OK, 0 rows affected (0.00 sec)\nUse CREATE TABLE ... LIKE to create an empty table based on the definition of another table, including any column attributes and indexes defined in the original table:
CREATE TABLE new_tbl LIKE orig_tbl;\nThe copy is created using the same version of the table storage format as the original table.
create table test1(a int, b float);\ncreate table test2 like test1;\nshow columns from test2;\n+-------+-------+------+------+---------+---------+\n| Field | Type | Null | Key | Default | Comment |\n+-------+-------+------+------+---------+---------+\n| a | INT | YES | | NULL | |\n| b | FLOAT | YES | | NULL | |\n+-------+-------+------+------+---------+---------+\n2 rows in set (0.11 sec)\nYou can create one table from another by adding a SELECT statement at the end of the CREATE TABLE statement:
CREATE TABLE new_tbl [AS] SELECT * FROM orig_tbl;\nCreate new columns for all elements in the SELECT. For example:
mysql> CREATE TABLE test (a INT NOT NULL AUTO_INCREMENT,\n -> PRIMARY KEY (a), KEY(b))\n -> SELECT b,c FROM test2;\nThis creates a table with three columns, a, b, and c. Notice that the columns from the SELECT statement are appended to the right side of the table, not overlapped onto it. Take the following example:
mysql> SELECT * FROM foo;\n+---+\n| n |\n+---+\n| 1 |\n+---+\n1 row in set (0.00 sec)\n\nmysql> CREATE TABLE bar (m INT) SELECT n FROM foo;\nQuery OK, 1 row affected (0.02 sec)\nRecords: 1 Duplicates: 0 Warnings: 0\n\nmysql> SELECT * FROM bar;\n+------+---+\n| m | n |\n+------+---+\n| NULL | 1 |\n+------+---+\n1 row in set (0.00 sec)\nThis statement creates a new trigger. A trigger is a named database object that is associated with a table, and that activates when a particular event occurs for the table. The trigger becomes associated with the table named tbl_name, which must refer to a permanent table.
CREATE\n [DEFINER = user]\n TRIGGER [IF NOT EXISTS] trigger_name\n trigger_time trigger_event\n ON tbl_name FOR EACH ROW\n [trigger_order]\n trigger_body\n\ntrigger_time: { BEFORE | AFTER }\n\ntrigger_event: { INSERT | UPDATE | DELETE }\n\ntrigger_order: { FOLLOWS | PRECEDES } other_trigger_name\nIF NOT EXISTS prevents an error from occurring if a trigger having the same name, on the same table, exists in the same schema.
trigger_time is the trigger action time. It can be BEFORE or AFTER to indicate that the trigger activates before or after each row to be modified.
trigger_event indicates the kind of operation that activates the trigger. These trigger_event values are permitted: INSERT: The trigger activates whenever a new row is inserted into the table (for example, through INSERT, LOAD DATA, and REPLACE statements). UPDATE: The trigger activates whenever a row is modified (for example, through UPDATE statements). DELETE: The trigger activates whenever a row is deleted from the table (for example, through DELETE and REPLACE statements). DROP TABLE and TRUNCATE TABLE statements on the table do not activate this trigger, because they do not use DELETE. Dropping a partition does not activate DELETE triggers, either. The trigger_event does not represent a literal type of SQL statement that activates the trigger so much as it represents a type of table operation. For example, an INSERT trigger activates not only for INSERT statements but also LOAD DATA statements because both statements insert rows into a table. trigger_body is the statement to execute when the trigger activates. To execute multiple statements, use the BEGIN ... END compound statement construct.
DROP TRIGGER [IF EXISTS] [schema_name.]trigger_name\nThis statement drops a trigger. The schema (database) name is optional. If the schema is omitted, the trigger is dropped from the default schema.

TRUNCATE [TABLE] tbl_name\nTRUNCATE TABLE empties a table completely. Logically, TRUNCATE TABLE is similar to a DELETE statement that deletes all rows, or a sequence of DROP TABLE and CREATE TABLE statements.
KILL Statement
KILL [CONNECTION | QUERY] processlist_id\nEach connection to mysqld runs in a separate thread. You can kill a thread with the KILL processlist_id statement.

See the config documentation for more details\nlistener.security.protocol.map=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL\n\n# The number of threads that the server uses for receiving requests from the network and sending responses to the network\nnum.network.threads=3\n\n# The number of threads that the server uses for processing requests, which may include disk I/O\nnum.io.threads=8\n\n# The send buffer (SO_SNDBUF) used by the socket server\nsocket.send.buffer.bytes=102400\n\n# The receive buffer (SO_RCVBUF) used by the socket server\nsocket.receive.buffer.bytes=102400\n\n# The maximum size of a request that the socket server will accept (protection against OOM)\nsocket.request.max.bytes=104857600\n\n\n############################# Log Basics #############################\n\n# A comma separated list of directories under which to store log files\nlog.dirs=/home/software/kafka_2.13-3.5.0/kraft-combined-logs\n\n# The default number of log partitions per topic. More partitions allow greater\n# parallelism for consumption, but this will also result in more files across\n# the brokers.\nnum.partitions=1\n\n# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.\n# This value is recommended to be increased for installations with data dirs located in RAID array.\nnum.recovery.threads.per.data.dir=1\n\n############################# Internal Topic Settings #############################\n# The replication factor for the group metadata internal topics \"__consumer_offsets\" and \"__transaction_state\"\n# For anything other than development testing, a value greater than 1 is recommended to ensure availability such as 3.\noffsets.topic.replication.factor=1\ntransaction.state.log.replication.factor=1\ntransaction.state.log.min.isr=1\n\n############################# Log Flush Policy #############################\n\n# Messages are immediately written to the filesystem but by default we only fsync() to sync\n# the OS cache lazily. The following configurations control the flush of data to disk.\n# There are a few important trade-offs here:\n# 1. Durability: Unflushed data may be lost if you are not using replication.\n# 2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.\n# 3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.\n# The settings below allow one to configure the flush policy to flush data after a period of time or\n# every N messages (or both). This can be done globally and overridden on a per-topic basis.\n\n# The number of messages to accept before forcing a flush of data to disk\n#log.flush.interval.messages=10000\n\n# The maximum amount of time a message can sit in a log before we force a flush\n#log.flush.interval.ms=1000\n\n############################# Log Retention Policy #############################\n\n# The following configurations control the disposal of log segments. The policy can\n# be set to delete segments after a period of time, or after a given size has accumulated.\n# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens\n# from the end of the log.\n\n# The minimum age of a log file to be eligible for deletion due to age\nlog.retention.hours=72\n\n# A size-based retention policy for logs. Segments are pruned from the log unless the remaining\n# segments drop below log.retention.bytes. Functions independently of log.retention.hours.\n#log.retention.bytes=1073741824\n\n# The maximum size of a log segment file.
