JSqlParser

JSqlParser is a SQL statement parser. It translates SQLs in a traversable hierarchy of Java classes. JSqlParser is not limited to one database but provides support for a lot of specials of Oracle, SqlServer, MySQL, PostgreSQL ... To name some, it has support for Oracles join syntax using (+), PostgreSQLs cast syntax using ::, relational operators like != and so on.

Contributions

To help JSqlParsers development you are encouraged to provide

• feedback
• bugreports
• pull requests for new features
• improvement requests
• fund new features
• a little donation

Please write in english, since it's the language most of the dev team knows.

Also I would like to know about needed examples or documentation stuff.

Extensions in the latest SNAPSHOT version 1.2

• support for single quoted aliases select col1 as 'alias'
• support for Unicode string literal like N'test' or U'test'
• support for bitwise not ~
• support for drop view
• support for indexed JDBC parameters at multiple places
• allowed index as object name
• switched to JavaCC modern template
• switched to JDK 1.7
• introduced more AST node links
• support for aliased table in insert into statement
• SQL_CALC_FOUND_ROWS support
• support for more complex expressions within case expr when expr then expr end.
• support for << and >> left and right shift operations
• breaking API change: merge of within group and over (window expressions)
• first support for use statements
• first support for call statements
• create table allows now quoted identifiers within primary key definition
• introduced alias for subquery in combination with a pivot definition (this changes alias handling within the library for pivot sqls)
• force the parser to fully parse a String using parseCondExpression or parseExpression

Extensions of JSqlParser releases

• Release Notes
• Modifications before GitHubs release tagging are listed in the Older Releases page.

Building from the sources

As the project is a Maven project, building is rather simple by running:

mvn package

The project requires the following to build:

• Maven
• JDK 1.7 or later. The jar will target JDK 1.6, but the version of the maven-compiler-plugin that JsqlParser uses requires JDK 1.7+

This will produce the jsqlparser-VERSION.jar file in the target/ directory.

To build this project without using Maven, one has to build the parser by JavaCC using the CLI options it provids.

Debugging through problems

Refer to the Visualize Parsing section to learn how to run the parser in debug mode.

Source Code conventions

Recently a checkstyle process was integrated into the build process. JSqlParser follows the sun java format convention. There are no TABs allowed. Use spaces.

public void setUsingSelect(SubSelect usingSelect) {
    this.usingSelect = usingSelect;
    if (this.usingSelect != null) {
        this.usingSelect.setUseBrackets(false);
    }
}

This is a valid piece of source code:

• blocks without braces are not allowed
• after control statements (if, while, for) a whitespace is expected
• the opening brace should be in the same line as the control statement

Maven Repository

JSQLParser is deployed at sonatypes open source maven repository. Starting from now I will deploy there. The first snapshot version there will be 0.8.5-SNAPSHOT. To use it this is the repository configuration:

<repositories>
     <repository>
         <id>jsqlparser-snapshots</id>
         <snapshots>
             <enabled>true</enabled>
         </snapshots>
         <url>https://oss.sonatype.org/content/groups/public/</url>
     </repository>
</repositories>

This repositories releases will be synched to maven central. Snapshots remain at sonatype.

And this is the dependency declaration in your pom:

<dependency>
	<groupId>com.github.jsqlparser</groupId>
	<artifactId>jsqlparser</artifactId>
	<version>1.1</version>
</dependency>
