I need to update all the rows in a MySql table like this:

START TRANSACTION;
update product set  t1="t1" where p_id=40717;
update product set  t1="3" where p_id=40713;
.....
commit;

The problem is that there can be thousands of rows and it is very slow.
Is there a better way to do it?

Thank you!
