Question

I have a simple query and a simple fetch row:

$quar=mysql_query("SELECT 
                    COALESCE(sum(impression),0) as imps
                   ,COALESCE(sum(clk_count),0) as clks
                   ,COALESCE(sum(money_spent),0) as monspen,time 
                  FROM `$table_name` 
                  WHERE $uid_str $aid_str $timestr time=$temp_time_main 
                  GROUP BY time 
                  ORDER BY time");

$row=mysql_fetch_row($quar);

echo '<pre>';
print_r($row);

The query runs ok, no error, not returning false. Echoed the query and tried in PhpMyAdmin, returning results ok.

Printing $row still returns nothing, tried with fetch assoc, fetch array too. Turned on error_reporting(E_ALL); and voila, print_r returns the array. Disabling error report, returns nothing again. What can be the problem?

May be this will help to debug the problem:

$query = "select COALESCE(sum(impression),0) as imps,COALESCE(sum(clk_count),0) as clks,COALESCE(sum(money_spent),0) as monspen,time from `$table_name` where $uid_str $aid_str $timestr time=$temp_time_main group by time order by time";

$result = mysql_query($query) || die('Error: ' . mysql_error());

while (($row=mysql_fetch_row($result)) !== false) {
  var_dump($row);
}
