php - 両方のSQLクエリを同時に機能させる

Question

1 つの php ファイルに 2 つのクエリがありますが、実行されるのは 2 番目のクエリだけです。しかし、最初のクエリは実行されません。私は何が間違っているのでしょうか？これが私のコードです。

<?php include('connections/pgconn.php'); ?>
<?php


function cleanData(&$str)
{
$str = preg_replace("/\t/", "\\t", $str);
$str = preg_replace("/\r?\n/", "\\n", $str);
if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"';
}

// filename for download
$filename = "eastafrica_revenue_monthly" . date('Ymd') . ".xls";

header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");

$flag = false;
$result = pg_query("SELECT to_char (a.CALLDATE,'yyyymm') as month,min(a.calldate) as   start_time,max(a.calldate) as end_time,
   sum(a.alltaxcost::integer) AS revenue,

and trim(a.zoneiddest)  = trim(b.country_code)
GROUP BY to_char (a.CALLDATE,'yyyymm') ,a.zoneiddest,b.country
ORDER BY 1");

while(false !== ($row = pg_fetch_assoc($result))) {

  echo implode("\t", array_keys($row)) . "\r\n";
