Application Express 5.1.2.00.09
Oracle 11g Release 2
I am new to Interactive Grid. I would like to add a validation but not on one row or one itme.
I would like to validate a row against other rows. For example, I want to include a validation that ensures that the user name entered in my User Security IG is not repeated. Only one row can contain JSMITH as the username. How do I accomplish that using PL/SQL?
Thank you,
Robert
