Dear Sirs, I have a database with thousands records. And every minutes I am selecting 50 rows from that database and send some data to another web url according sellected 50 rows. Whenever, my script finish job in one minute, I have no problem. Because after each transaction, I am uptading one of the rows field as a "uesd". BUT! if my script can not finish sending data to another url due to low speed connection or such a problem. On the next minute, same script runs automaticlay and sellecting another 50 rows which are not marked by "used". In this case, some times these two running acripts are sellecting same rows due to, old one haven't marked as a "used" for sellected rows. Is there any way, to put flag or something like that, when sellecting rows with php and mysql?
