Hi. I'm looking for the most efficient way to insert several records and retrieve the auto_increment values for the inserted rows, while avoiding crippling concurrency problems caused by multiple php threads doing this on the same table at potentially the same time. I'm using mysql atm, so i thought "stored procedures!".. But alas, mysql docs are very basic. I got the gist of how to setup a stored proc, but how to retrieve a list of auto_increment ids still eludes me; last_insert_id() only returns for the last row i believe. So building an INSERT (...) VALUES (...),(...) at the php end, is probably not the way to go then. But the mysql docs don't show how to pass an array to a stored procedure, so i can't just have the stored proc loop over an array, insert per row, retrieve last_insert_id() into temp table, and return the temp table contents for a list of auto_increment ids for inserted rows. Any clues are greatly appreciated.. I'm looking for the most sql server independent way to do this. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
