ID: 14086 User updated by: oliver@samera.com.py Reported By: oliver@samera.com.py Status: Bogus Bug Type: MySQL related Operating System: Linux 2.4 PHP Version: 4.0.4pl1 New Comment: But, can I free a result set that returned mysql_query in mysql_result_free? Does this code works? : // here I'm successfully conected using mysql_pconnect(); $result = mysql_query("insert into table1(col1) values(1)"); if($result) { // here I get a warning only if I used a insert statment mysql_free_result($result); } Previous Comments: ------------------------------------------------------------------------ [2001-11-16 13:11:03] derick@php.net From the manual: (http://uk.php.net/manual/en/function.mysql-query.php): mysql_query() returns TRUE (non-zero) or FALSE to indicate whether or not the query succeeded. A return value of TRUE means that the query was legal and could be executed by the server. It does not indicate anything about the number of rows affected or returned. It is perfectly possible for a query to succeed but affect no rows or return no rows. <snip> For SELECT statements, mysql_query() returns a new result identifier that you can pass to mysql_result(). When you are done with the result set, you can free the resources associated with it by calling mysql_free_result().
