呼叫一个成员函数查询（）非对象上

Question

<?php  
$serverName = "servername"; 
$connectionInfo = array("Database"=>"DB", "UID"=>"user1", "PWD"=>"user@123"); 
$conn = sqlsrv_connect($serverName, $connectionInfo); 
if($conn) { 
    echo "Connection established.<br />"; 
} 
else{ 
    echo "Connection could not be established.<br />"; 
    die(print_r(sqlsrv_errors(), true)); 
} 
$sql = "SELECT 
     COUNT(CASE WHEN online = 'Yes' THEN city END) AS o_total, 
     COUNT(CASE WHEN online = 'No' THEN city END) AS o_offline, 
     COUNT(*) as t_total, 
     COUNT(CASE WHEN online = 'Yes' AND channel='Name1' THEN city END) AS o_Name1, 
     COUNT(CASE WHEN channel='Name1' THEN city END) AS t_Name1, 
     COUNT(CASE WHEN online = 'YES' AND channel='Name2' THEN city END) AS o_Name2,

     COUNT(CASE WHEN channel='Name4' THEN city END) AS t_Name4, 
     city FROM wmm group by city"; 
     $result = $conn->query($sql); 

     $array = new stdClass(); 
     if ($result->num_rows > 0) { 
      while($row = sqlsrv_fetch_assoc($result)) { 
       $array->$row['city'] = $row; 
      } 
      echo json_encode($array); 

     }

解决this..thanks尝试连接这样：

<?php  
$dbservername= "servername"; 
$dbusername="user1"; 
$dbpassword="user@123"; 
$dbname="DB"; 
$conn = new mysqli($dbservername, $dbusername, $dbpassword, $dbname); 
if($conn->connect_error) { 
    echo "Connection could not be established.<br />"; 
    die(print_r($conn->connect_error, true)); 
} 
else{ 
    echo "Connection established.<br />"; 

     $sql = "SELECT 
     COUNT(CASE WHEN online = 'Yes' THEN city END) AS o_total, 
     COUNT(CASE WHEN online = 'No' THEN city END) AS o_offline, 
     COUNT(*) as t_total, 
     COUNT(CASE WHEN online = 'Yes' AND channel='Name1' THEN city END) AS o_Name1, 
     COUNT(CASE WHEN channel='Name1' THEN city END) AS t_Name1, 
     COUNT(CASE WHEN online = 'YES' AND channel='Name2' THEN city END) AS o_Name2, 
     COUNT(CASE WHEN channel='Name2' THEN city END) AS t_Name2, 
     COUNT(CASE WHEN online = 'Yes' AND channel='Name3' THEN city END) AS o_Name3, 
     COUNT(CASE WHEN channel='Name3' THEN city END) AS t_Name3, 
     COUNT(CASE WHEN online = 'Yes' AND channel='Name4' THEN city END) AS o_Name4, 
     COUNT(CASE WHEN channel='Name4' THEN city END) AS t_Name4, 
     city FROM wmm group by city"; 
     $result = $conn->query($sql); 

     $array = new stdClass(); 
     if ($result->num_rows > 0) { 
      while($row = sqlsrv_fetch_assoc($result)) { 
       $array->$row['city'] = $row; 
      } 
      echo json_encode($array); 

     } 
} 


?>

sqlsrv_connect()不会返回一个对象，而是一个资源。

您需要致电sqlsrv_query()并将$conn资源作为第一个参数，将查询作为第二个参数传递。
