What's the Best SQL Parsing Library for Java Developers?

Java SQL parsing solution

Parsing SQL statements is critical for applications that interact with databases. For Java developers, finding the right SQL parsing library is crucial.

Open source SQL parsing library

For the open source option, ANTLR3 is recommended. It provides an ANSI SQL syntax that you can leverage to create custom parsers. ANTLR4 also provides a SQL syntax for parsing.

Flexibility and vendor-specific syntax

If your needs include parsing vendor-specific syntax, you will need to consider a library that supports customization or flexibility. ANTLR4's SQL syntax allows extension and modification to handle vendor-specific syntax.

Strictly adhere to SQL standards

If you need to strictly adhere to the SQL standard, you can choose a library that follows SQL syntax exactly. These libraries provide reliable options for parsing SQL statements without introducing vendor-specific differences.

SQL rewriting application

The need for SQL parsing can extend beyond providing SQL interfaces to non-SQL databases. It can also be used to rewrite SQL before execution. For example, you might want to rewrite Oracle-specific SQL to be compatible with other databases. A flexible parser that allows such rewriting can simplify this process.
