Creating Multi-Column Primary Keys in Derby DB Tables
I’m trying to create tables in a Derby database, using the wizards provided in DB Explorer. I don’t see any way to specify a primary key that consists of more than one column. Do I need to create a multi-column primary key manually using an SQL statement, or is there a way to make one of the wizards do it for me?

While adding the colums you can check the Primary Key check box for every column that you want to add as a primary key. (Im referrring to the column wizard window)
