ID: 16295 Updated by: joyeux@1984.cz Reported By: joyeux@1984.cz -Status: Bogus +Status: Open Bug Type: MySQL related Operating System: MDK 8.2 PHP Version: 4.1.2 New Comment: I try to put mysql_query everywhere (there are no mysql_unbuffered_queryies) Still the same. What's important? mysql_errno is always null and the error occures in various resources. Result of faulty operation in a database is sometimes ok and sometimes not. Previous Comments: ------------------------------------------------------------------------ [2002-03-27 06:16:04] georg@php.net Don't mix mysql_unbuffered_query and mysql_query. mysql_unbuffered_query is for fetching rows in SELECT, SHOW or DESCRIBE statements without buffering it.
