The database HSQLDB requires this primary key for every tabe - if you will work with the table in GUI. > Also the primary key is used on tables in all sorts of > databases. It is not only valid for Embedded databases. This is wrong. Have a look at DBase, MySQL or, very simple, have a look at HSQLDB without using the GUI. You could create tables in this database without using a primary key and you could also add values to this tables. The wizard works with this feature.
