I am using two tables.

I want to make a trigger whenever the User tables firstname or lastname is updated. I want change this contactinfo’s Name to whatever they changed in the User table. Is it possible through trigger?

Answer 1

The general syntax of CREATE TRIGGER is :

CREATE TRIGGER trigger_name trigger_time trigger_event ON tbl_name 
FOR EACH ROW trigger_statement

Take a look at examples from http://www.roseindia.net/mysql/mysql5/triggers.shtml and http://dev.mysql.com/doc/refman/5.1/en/create-trigger.html
