Good afternoon, you guys. The language I’m using is Delphi 4. I have a question on how to check if a record already exists in DB Grid. The values I want to enter in Dbgrid will be typed in a DB Edit. The table has two primary keys. If the set of primary keys is equal to some database record, the system will prevent the insertion of the record in Dbgrid.
Hello, Sami. I used Dataset to solve this problem. Thank you.
