#22100 [Csd->Bgs]: Query failure when WHERE clause matches on column with value '0'

ID: 22100 Updated by: magnus@php.net Reported By: eigenuser@yahoo.com -Status: Closed +Status: Bogus Bug Type: PostgreSQL related Operating System: FreeBSD 4.7 PHP Version: 4.3.0 New Comment: Not a PHP bug => Bogus Previous Comments: ------------------------------------------------------------------------ [2003-02-08 02:07:22] eigenuser@yahoo.com This must've been a PostgreSQL bug, not PHP. I installed php4-STABLE-200302080430, and the problem was still there. I noticed a new release of PostgreSQL, so I upgraded from 7.3.1 to 7.3.2, and now everything seems to be fine. ------------------------------------------------------------------------ [2003-02-07 06:31:39] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip ------------------------------------------------------------------------ [2003-02-06 18:05:51] eigenuser@yahoo.com I have a PostgreSQL db with the table 'news_article', which has its primary index a serial column named 'art_id'. This table has a row whose art_id is set to zero. Now I'll do the following: 1. Make a persistent connection. 2. Make query of the form: SELECT * FROM news_article WHERE art_id = 0 Most of the time this query will work fine, but if I refresh the PHP script multiple times, I'll eventually get an error with the following error messages. ------------------- PHP error message: ------------------- Warning: pg_query() [function.pg-query]: Query failed: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. .in [filename.php] on line 21 -------------------------- PostgreSQL error message: -------------------------- pq_recvbuf: recv() failed: Undefined error: 0 Some things I've noticed: * This problem does not seem to appear when connecting with non-persistent connections. * Although the PHP error message suggests the connection was closed prematurely, you can still issue successful queries using the same connection resource later on in the PHP page, so it appears that the connection is still open. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=22100&edit=1
