I am looking for a DDL generation tool, preferably command line, that can convert DDL of one RDBMS to another - say DDL of Oracle schema/table to MySQL/SQL Server & vice-versa. I have reviewed Oracle's SQL Developer - its DDL generation is one way MySQL to Oracle, SQL Server to Oracle etc.

I would prefer a general-purpose DDL conversion tool/utility if one exists! Also, is there a way to use GGs DDLGEN for this ? I have explored this a bit but it seems all conversions are from Tandem DDL to DDL of various RDBMS.

Thanks,
