I’m confused abt running transactions through php script.
In my MySql autocommit is set to 1,
yet when I run a script

ex: mysql_query(“START TRANSACTION”);

$sql="INSERT INTO 
`address`(`Address_Id`, 
`Address_Line1`, 
`Address_line2`, 
`Zip`, 
`Created_By`,
 `Created_Date`, 
 `Updated_By`, 
 `Updated_Date`) 
VALUES ('2','this is test1','test2','210','SYSTEM','NOW()','SYSTEM','NOW()')";

mysql_query($sql);

When I don’t give commit, inserted records in the table is zero.
the record comes up only if I give commit command.

Also please tell me what happens if in a php script I start transaction and then dont give either roll back or commit statements

    http://dev.mysql.com/doc/refman/5.5/en/commit.html:

    By default, MySQL runs with autocommit mode enabled. This means that as soon as you execute a statement that updates (modifies) a table, MySQL stores the update on disk to make it permanent.

    But if you specify START TRANSACTION explicitly – then it isn’t taken into account, so you work in a transaction that should be committed.
