while while循環放慢腳本內的多個查詢

-1

while循環內的多個查詢確實減慢了腳本..實際上我想要的是工程師列表假設它是20 ..特定工程師已經完成了多少修復。。我的代碼如下while while循環放慢腳本內的多個查詢

所有查詢相關的或者這一切有什麼不同？ –

由於每個查詢只是簡單地改變工程師變量，所以你可以在while循環之外運行每個查詢的一個版本，並且如果你找到了你的答案，使用'GROUP BY ContactCenter.assignedTo' – Anthony

，如果你在這裏發佈它會是非常好的。 – mandza

您可以使用MySQL API的多查詢功能在PHP。

<?php 
$mysqli = new mysqli("localhost", "my_user", "my_password", "world"); 

/* check connection */ 
if (mysqli_connect_errno()) { 
    printf("Connect failed: %s\n", mysqli_connect_error()); 
    exit(); 
} 

$query = "SELECT CURRENT_USER();"; 
$query .= "SELECT Name FROM City ORDER BY ID LIMIT 20, 5"; 

/* execute multi query */ 
if ($mysqli->multi_query($query)) { 
    do { 
     /* store first result set */ 
     if ($result = $mysqli->store_result()) { 
      while ($row = $result->fetch_row()) { 
       printf("%s\n", $row[0]); 
      } 
      $result->free(); 
     } 
     /* print divider */ 
     if ($mysqli->more_results()) { 
      printf("-----------------\n"); 
     } 
    } while ($mysqli->next_result()); 
} 

/* close connection */ 
$mysqli->close(); 
?>

你應該在子查詢計數循環使用一個查詢...
