I would like to create a trigger on a file (Shop Number) to discipline the relation data between two fields [Closing Date] and [Open]. If [Open] is true then [Closing Date] is NULL. If [Open] is false then [Closing Date] contains a datetime.

Would soneone help me with the code for this trigger? I am new at triggers.

sound like a check constraint to me

ALTER TABLE SHopNumber ADD CONSTRAINT Chk_ClosingDate CHECK ([Closing Date] IS NOT NULL OR [Open] = 1)
