Yes, basically something like this: create procedure foobar() begin select * from table_1; select * from table_2 end; I know that at least SQL Server and MySQL can do that. Maybe others as well (Sybase most probably). But I always failed do see the actual advantage of that because the results can't be "used" any further (e.g. in a JOIN ora subselect). I also don't understand why having a single procedure doing a lot of stuff is better than having several procedures (or functions)doing one defined thing. From a JDBC point of view the code simply asks the Statement whether it has any more result sets and loops over this until all results are returned. Thomas
