>Thank you, Borislav. Is there a way to check if INSERTED is empty? This way, if INSERTED is empty, I would know that the trigger was called by DELETE action. I am thinking of trying the syntax EMPTY( INSERTED ) but it is probably wrong.

IF NOT EXISTS(SELECT * FROM INSERTED)
   BEGIN
   --- Only DELETED has records
   END
