Example
This example creates a trigger that inserts a record to a second table (MyAudit) after a record is inserted into the table the trigger is defined on (MyTable). Here the "inserted" table is a special table used by Microsoft SQL Server to store affected rows during INSERT and UPDATE statements; there is also a special "deleted" table that performs the same function for DELETE statements.
CREATE TRIGGER MyTrigger
ON MyTable
AFTER INSERT
AS
BEGIN
-- insert audit record to MyAudit table
INSERT INTO MyAudit(MyTableId, User)
(SELECT MyTableId, CURRENT_USER FROM inserted)
END
