Hi Balaji, I Think for MySQL 5 Version you should use Stored Procedure because in my opinion, stored procedure is faster, safer and cleaner. The sample : CREATE PROCEDURE TEST() BEGIN START TRANSACTION Insert Into .... Update .... COMMIT END Table Type that can use Transaction is the table that using InnoDB as table Engine. MyISAM Table Engine is more appropriate for Master Table with low data transaction. I Think you'll find more by googling.
