Now you can fully incorporated this DB2 SQL parser into your products, instantly adding a powerful SQL processing capability to your program. With the right library, you can get your job done quickly by saving hundred of hours, if not more, on developing time.

Clean up messy SQL codes

Easily integrate SQL formatter into your application for a color coded layout that is easy to navigate, giving your product a professional feeling.

Detect SQL syntax errors

Your application will be able to validate SQL syntax before a database executes the query. This is very useful especially if your SQL was dynamically built based on user input.

Rid SQL injections

Quickly locate the primary key and/or foreign key in DDL scripts to figure out the complex relationship among the various tables. Extracted table, attribute names, data types can be used to generate the CRUD-Statements.

Parsing SQL is a notoriously difficult task, but we are here to help. You will be provided with a SQL query parse tree in XML output that will allow you to further process SQL scripts.

Rewrite and convert SQL
