Question 1

How to parse a SQL query in Java using JSqlParser?

Accepted Answer

Use CCJSqlParserUtil.parse() to get a PlainSelect object, then navigate the AST with getters for select items, from clause, and where conditions, as shown in the README code sample. This allows programmatic access to SQL elements.

Question 2

JSqlParser vs JOOQ for SQL parsing?

Accepted Answer

JSqlParser is focused on parsing and AST manipulation with broad multi-dialect support, while JOOQ offers a handwritten parser with dialect translation and a full SQL builder. JOOQ is dual-licensed, but JSqlParser is more open-source friendly under LGPL/Apache.

Question 3

Does JSqlParser support MySQL stored procedures?

Accepted Answer

The supported grammar lists CREATE and ALTER statements, but specific stored procedure syntax might be limited; it's community-driven, so missing features can be requested or contributed via issues.

Question 4

What caused the performance issues in JSqlParser 5.2?

Accepted Answer

A commit related to FunctionAllColumns introduced a regression, but it was fixed in version 5.3 with added JMH benchmarks to prevent future issues, showing active maintenance.

Question 5

How to build SQL statements programmatically with JSqlParser?

Accepted Answer

JSqlParser provides a fluent API to construct SQL from Java code; check the website samples for examples of building SELECT, INSERT, and other statements using the AST classes directly.

Question 6

Is JSqlParser compatible with Java 8?

Accepted Answer

No, version 5.0 and later require JDK11, with JSQLParser-4.9 being the last JDK8 compatible version, so upgrades may force Java version updates in legacy projects.
