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

You should issue a query to verify the existence of other record with the same values for those fields before inserting the new one, and display the message if necessary.

If those fields are the primary key of the table, you could possibly try the insertion and manage the exception raised for the PK violation.
