Semantic Diff for SQL
I wonder if this is a topical thread to check if anyone is aware of a Java based solution to parse a CREATE VIEW statement to get a mapping between the view columns and the corresponding source table columns. I checked out jsqlparser[0] and it does produce an AST which can be parsed using the visitor-pattern[1] but was wondering if there is a more "out-of-the-box" solution. Due to various reasons, querying the database information schema is not an option I can pursue.

JSQLParser can parse multiple SQL dialects like MySQL, Postgres and Oracle. The grammar can be modified to support other SQL dialects.

Interesting coincidence - I'm working on a parser that parses the AST produced by JSqlParser[0] for a create view statement to generate mapping between the columns of a view and the columns of its underlying table. It is an interesting example of having to use the visitor pattern[1].
