+
+
+# Dependencies
+
+This project has a parent pom, [liquibase-snowflake-db-build](https://github.com/bruce-szalwinski/liquibase-snowflake-db-build), that manages the common dependencies.  Install that before continuing.
+
+# Setup
+
+Create a file called `db.properties` containing the contents below.  Store this file on your file system.
+
+```bash
+# update with your account information
+snowflake.account=12345
+db.username=my_user
+db.password=my_password
+db.database=my_database
+db.warehouse=my_warehouse
+db.schema=my_schema
+
+db.host=${snowflake.account}.snowflakecomputing.com
+db.url=jdbc:snowflake://${db.host}/?db=${db.database}&warehouse=${db.warehouse}&schema=${db.schema}
+db.driver=net.snowflake.client.jdbc.SnowflakeDriver
+
+liquibase.verbose: true
+liquibase.dropFirst: false
+liquibase.logging: debug
+liquibase.driver: ${db.driver}
+liquibase.url: ${db.url}
+liquibase.username: ${db.username}
+liquibase.password: ${db.password}
+liquibase.defaultCatalogName: ${db.database}
+liquibase.defaultSchemaName: ${db.username}
+liquibase.contexts:
+```
+
+Define an environment variable `DB_PROPERTIES` that points at the location of this file.
+
+```bash
+export DB_PROPERTIES=$HOME/db.properties
+```
+
+# Creating changes
+
+The [master.xml](src/main/resources/master.xml) is the top level [databasechangelog](https://www.liquibase.org/documentation/databasechangelog.html) for the project.  It contains a list of changelogs, organized by year.  Each of the yearly changelogs contains a list of changes for that year.  To add a change, create a file in the yearly directory and update the `changelog.xml` in that directory to include the newly created file.  See [changelog](src/main/resources/changesets/2020/changelog.xml) as an example.
+
+This project currently just uses `plain SQL` [changelog files](https://www.liquibase.org/documentation/sql_format.html).  Each changelog file contains one or more `changeset` entries, with each entry having an `author:id` tag.  See [BPS-1.sql](src/main/resources/changesets/2020/BPS-1.sql) for an example.
+
+
+# Applying changes
+
+With the changes in place, apply them with:
+
+```bash
+mvn install
+```
+
+# Resolving common issues
+## Session does not have a current database
+
+### Issue
+```bash
+[ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:3.8.5:update (default) on project sample-app: Error setting up or running Liquibase: liquibase.exception.DatabaseException: Cannot perform CREATE TABLE. This session does not have a current database. Call 'USE DATABASE', or use a qualified name. [Failed SQL: CREATE TABLE MY_SCHEMA.DATABASECHANGELOGLOCK (ID INT NOT NULL, LOCKED BOOLEAN NOT NULL, LOCKGRANTED TIMESTAMP_NTZ, LOCKEDBY VARCHAR(255), CONSTRAINT PK_DATABASECHANGELOGLOCK PRIMARY KEY (ID))] -> [Help 1]
+[ERROR]
+```
+
+### Resolution
+Ensure that the user has a default role.
+```sql
+alter user my_user set default_role = my_default_role
+```
+
+## No active warehouse
+
+### Issue
+```bash
+[ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:3.8.5:update (default) on project sample-app: Error setting up or running Liquibase: liquibase.exception.DatabaseException: No active warehouse selected in the current session.  Select an active warehouse with the 'use warehouse' command.
+[ERROR]  [Failed SQL: DELETE FROM MY_SCHEMA.DATABASECHANGELOGLOCK]
+[ERROR] -> [Help 1]
+```
+
+### Resolution
+
+In the db.properties file, set `defaultSchema` equal to `db.username`.
