What is JSqlParser?

JSqlParser parses an SQL statement. Then the result can be accessed in a structured way. The generated Java class hierarchy can be navigated using the Visitor Pattern.

#Modifications This fork is continuously improved. All modifications could be followed at the Release Notes.

Modifications before GitHubs release tagging are listed in the [Older Releases](Older Releases) page.

How it works?

The parser is built using JavaCC. The core JavaCC grammar for SQL has been taken from Guido Draheim's site and has been changed in order to produce a hierarchy of Java classes. Over the time the grammar was extended and now is a combination of the grammars of various database systems. So some (not all) Oracle, MySql, SQLServer, PostgreSQL specific aspects can be parsed.

Maven

To use JSqlParser in a maven project you have to include the following dependency:

<dependency>
    <groupId>com.github.jsqlparser</groupId>
    <artifactId>jsqlparser</artifactId>
    <version>0.9</version>
</dependency>

Be sure you added the latest release.
