Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The driver maybe pre-allocating memory at the time of the fetch, hence the OOM. Previous Comments: ------------------------------------------------------------------------ [2007-12-11 07:56:06] php at seven dot net dot nz Description: ------------ Selecting a large number of rows in a prepared statement results in an OOM error after execute() is called. The SQL server is located on a different box. I have not been able to pinpoint the exact number of rows as it is a moving target. It has failed on as low as 20k and as high as 50k. Obviously it would result in OOM if I had selected everything into an array, but from what I gather results should not be being sent to PHP until the fetchXYZ functions are called. Or am I wrong? It worked with 5.2.0 on the same box. Reproduce code: --------------- <?php $database = new PDO ( 'dblib:host=10.9.8.213;dbname=realenz', 'sa', 'loo0nieP' ); $query = "SELECT TOP 50000 * FROM nc_listing_full"; $statement = $database->prepare ($query); $statement->execute (); ?> Expected result: ---------------- Query to execute Actual result: -------------- Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 4 bytes) in /www/data/realestate-dev/scripts/htdocs/cron/rebuild_listings.php on line 12 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43561&edit=1
