Mixing of GROUP columns??

[Jessica]

Could someone help me fix this:
[code]$get_items = "SELECT count(*) AS wood_count, unique_id FROM items WHERE owner = '$cookie_userid' AND location = 'inventory' AND item_id = 22";
if ($db_result = $db_conn->Execute($get_items)) {
    if ($db_result->RecordCount()) {
        while (!$db_result->EOF) {
            $wood_ids[] = $db_result->fields['unique_id'];
        }
        $wood_count = $db_result->fields['wood_count'];
    }
    $db_result->Close();
} else
    die('SQL Error #'.$db_conn->ErrorNo().': '.$db_conn->ErrorMsg());
[/code]

It gives the error
SQL Error #1140: Mixing of GROUP columns (MIN(),MAX(),COUNT(),...) with no GROUP columns is illegal if there is no GROUP BY clause

Thanks.

I can't be much more informative than the error you already got. COUNT(*) is a group function, it operates on lots of rows. You can't mix group functions and columns for which you want per-row detail.

You are just trying to get a row count of your result, but that's why there is a mysql_num_rows() function (->RecordCount() with your database wrapper). Use that instead.

[code]$get_items = "SELECT unique_id FROM items WHERE owner = '$cookie_userid' AND location = 'inventory' AND item_id = 22";
if ($db_result = $db_conn->Execute($get_items)) {
    if ($db_result->RecordCount()) {
        while (!$db_result->EOF) {
            $wood_ids[] = $db_result->fields['unique_id'];
        }
        $wood_count = $db_result->RecordCount();
    }
    $db_result->Close();
} else
    die('SQL Error #'.$db_conn->ErrorNo().': '.$db_conn->ErrorMsg());[/code]

Thank you. So it's because of the unique_id being in there too?
