Problem with subqueries
hi, I have some sql code that I need to use with mysql it uses nested queries and since mysql doesn't implement them I would like to know how to do this. SELECT * FROM apartamentos WHERE vendido=0 AND Concelho=$row[ConcelhoP] AND Localidade LIKE '$row[LocalidadeP]' ... WHERE Referencia NOT IN ( SELECT Referencia FROM historico_clientes WHERE NumCliente=$id) Best Regards, Luis Rodrigues - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Problem with subqueries
MySQL does not support sub-queries.
