Fire a trigger after the update of specific columns in MySQL

Question

In MySQL, I want to fire a trigger after the update of specific columns.

I know how to do it in Oracle and DB2:

CREATE  TRIGGER  myTrigger
A         


        

Answer 1

As a solution, I did like that:

CREATE  TRIGGER  myTrigger
AFTER UPDATE  ON myTable
FOR EACH ROW
BEGIN
IF NEW.myColumn1 <> OLD.myColumn1 || NEW.myColumn2 <> OLD.myColumn2
then

.....

END IF
END
