Thanks for your answer, I´ve created a TEMPORARY table and it seems to work well for my purpose, the only doubt I still have is, if the table gets automatically deleted when the user closes the connection, or should I do something within my script to avoid a stack overflow? if there are too many simultaneous connections which create several temporary tables is it posible to knock down the server?
