Hi, Sorry for the quick re-post ... I see that the catalog and schema patter are actually part of the Java API. I thought they were something you had implemented. Sorry for the confusion.
I am still a little confused about how to use the schema patter to search for multiple schemas though. If you have any pointers I would appreciate it.

I have a few questions about this: 1) Will it break anything to add the schema to the 'clone' / 'equals' methods? 2) I see mention of an unused 'catalog' variable in a few places ... what exactly is this? 2) I noticed a default schema pattern of '%' ... could I use this to filter for only the schemas mentioned in the schema definition xml? If so could you maybe provide a quick example (I'm thinking something like " 'my_%','the_schm','%_schm' ") This has been quite fun to work on so far ... you guys have done a great job.

For servers like PostgreSQL and Oracle which do support separate schemas within a single database I shouldn't need to create a new db each time I need a new schema. Does this make sense? DdlUtils' support for schemas within the database is weak at the moment. You can create tables etc. within a specific schema by prefixing the table names etc. with the schema. E.g. <database name="test"> <table name="testschema.test"> ... </table> </database> For databases like Oracle, you can achieve somethin similar by accessing the database using a user corresponding to the schema. E.g. to place something in schema 'testschema', create the schema indirectly by creating a user of the same name, and then use this user to connect to the database. Any tables created via an unqualified name will then be placed in that schema. This also works for reading the database model from a schema (using the schema pattern to restrict which schemas to read from).
