Hi again? I dont understand how to use this two? I read php.net and other sites, but dont understand... I have this four tables: table1, 2, 3 and 4 So the SELECT is like this?: <? $query_select = "SELECT * FROM table1 FULL JOIN table2 FULL JOIN table3 FULL JOIN table4 ON table1.id=table2.id=table3.id=table4.id ORDER BY id ASC?; mysql_query($query_select); ?> This is with FULL JOIN... How identificate the left table if I want to use LEFT JOIN? How is the UPDATE? And the INSERT I dont understand yet how is it? I?m not to do a link between tables in PHPMyAdmin? Thank you very... VERY... much! + _ // Emiliano Boragina _ // Diseño & Comunicación ////////////////// + _ // emiliano.boragina@xxxxxxxxx / // 15 40 58 60 02 /////////////////////////// + _
