Hi,
My stored procedure receives a value of an equipment ID (optional; that is, an empty string could be passed).
In the SP I want to find if such ID exists and if so, set the value of the equipment PK.
How do I test if the value of @EquipPk is NULL (record not found) on one line with the SELECT?
IF @EquipmentID <> '' and @EquipPk = (SELECT EQUIP_PK FROM EQ_FILE where ID_NUMBER = @EquipmentID)
BEGIN
ENDTIA
