MySQL SQL Parser for Java and .NET

Example

MySQL SQL that GSP parses

CREATE PROCEDURE sync_totals()
BEGIN
  DECLARE done INT DEFAULT 0;
  UPDATE totals t JOIN orders o ON o.cid = t.cid SET t.amt = o.amt;
END

Parse it in Java

import gudusoft.gsqlparser.*;

TGSqlParser parser = new TGSqlParser(EDbVendor.dbvmysql);
parser.sqltext = sql; // the MySQL SQL above
if (parser.parse() == 0) {
    System.out.println(parser.sqlstatements.size() + " statement(s) parsed");
} else {
    System.out.println(parser.getErrormessage());
}

The .NET edition exposes the same API in C# — see the C# quick start.

Coverage

What GSP handles in MySQL

• Stored procedure blocks
• Cursors and loops
• LOAD DATA statements
• PREPARE/DEALLOCATE prepared statements
• SHOW and OPTIMIZE TABLE
• Procedural SQL: Stored procedures, functions, and triggers with DECLARE, cursors (OPEN/FETCH), and LOOP/REPEAT/WHILE control flow

Beyond parsing, the same AST powers table/column extraction, validation, formatting, and column-level lineage for MySQL.
