Sorry to chose this as the title..
I wanted to know the DB2's equivalent od ROW-ID concept of oracle. If i do not explicitly mention during the DDL of Table creation (DB2) what is the other alternative?

Thanks!

I am not sure about the row-id on Oracle, but in DB2 it must be defined as a column in the DDL to be used in SQL DML.

A possible workaround is to access data via a cursor and then update/delete the row "where current of cursor." This helps where a unique key does not exist.
