Bug #14086 Updated: If you use the result set of a insert query, you get a warning message.

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: Sorry about the confusion, as the manual says, only if you use a SELECT statement you can free the result using mysql_free_result(). My fault. This really is a bogus bug report. :-) Thanks for the is_resourece() tip. Oliver Previous Comments: ------------------------------------------------------------------------ [2001-11-16 13:44:17] hholzgra@php.net please *read* the manual page or at least the snippet from the previous message mysql_query() will only return a result set on SELECT statements in any other case it will just return true or false which do not need to be freed if you realy want to be sure you can do something like $res = mysql_query(...); if($res) { if(is_resourece($res)) { ... process result set ... mysql_free_result($res); } else { ... just be happy that your statement succeded .. } } else { ... error handling ... } ------------------------------------------------------------------------ [2001-11-16 13:34:16] oliver@samera.com.py 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); } ------------------------------------------------------------------------ [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(). Not a bug, but intended behavior >> bogus ------------------------------------------------------------------------ [2001-11-16 11:30:05] oliver@samera.com.py Tested in RedHat 7.1 with official updates. ------------------------------------------------------------------------ [2001-11-16 11:29:01] oliver@samera.com.py Summary changed ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
