I want to generate the next avalable key when INSERTing new rows. For an example... Create Table DBALIB/PARENT ( PARKEY BIGINT NOT NULL WITH DEFAULT PRIMARY KEY, PARNAME CHAR (30) NOT NULL WITH DEFAULT); INSERT INTO PARENT ( PARKEY, PARNAME) VALUES ( PARKEY(MAX) + 1), (<=====> just for illustration) 'BOBBY')

Thanks. We'll let you know when a new response is added.

In DB2:

Create your field with attributes

INTEGER NOT NULL GENERATED ALWAYS AS IDENTITY(START WITH 1, INCREMENT BY 1)

Or, replace NOT NULL with PRIMARY KEY. Don’t call out the field in the INSERT field list.

In Oracle, declare a sequence, and then use .NEXTVAL.
