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.

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 ...
}

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);
}

>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
