Parsing SQL is a notoriously difficult task because the syntax is very ambiguous in a lot of places. Many people have attempted to write a full SQL grammar with ANTLR and failed.

This product will provide you with a full SQL parser (initially Microsoft T-SQL as per SQL Server 2005, but soon to include Oracle, DB2 and perhaps others), which will produce an Abstract Syntax Tree (AST), and a Tree Parser to navigate the resulting AST. The product also provides a generator API (you are free to use your own coded actions of course, should you prefer.) In short, this should be everything you need to produce anything from a syntax analyzer, formatter, meta-data constructor, or even a full on SQL engine, syntactically compatible with the major variants (though you need to supply your own query engine).

We have various ways of providing this to you, from a binary only, royalty-based payment, to a one off, royalty-free payment that includes full source code. We will work with you to find a mutually beneficial way to work together.
