Question

我有一个网页，它会根据用户将选择的某个下拉列表选项显示信息。为了查看数据，我有多个查询运行以确定将显示哪些数据。如果我只使用1个查询和pdo语句，它对我有用。但是，我有多个查询和pdo语句，当我尝试使用倍数时，我得到一个Internal Server Error。

有人可以就问题可能提出一些建议吗？以下是我的一个查询和PDO语句的示例：

$_400p_1_1 = "SELECT CAST([Program_ID] AS INT) AS Program_ID
      ,CAST([Series] AS INT) AS Series
      ,[Supplier_Group_Name]
      ,[Buyer Group Name]
      ,[Fund Name]
      ,CAST([Agreement_ID] AS INT) AS Agreement_ID
      ,[Location Group Name]
      ,[Product Group Name]
      ,[Shipping Group Name]
      ,CAST([Tier_ID] AS INT) AS Tier_ID
      ,[Retro_to_1]
      ,CAST([Payments per Year] AS INT) AS [Payments per Year]
      ,[Condition Unit of Measure]
      ,CAST([Condition Minimum] AS INT) AS [Condition Minimum]
      ,CAST([Condition Maximum] AS INT) AS [Condition Maximum]
      ,CAST([Incentive Multiplier] AS DEC(5,4)) AS [Incentive Multiplier]
  FROM [test].[dbo].[vExample]
  WHERE [Supplier_Group_Name] = '$supp' AND [Series] = 1 AND [Fund Name] = '400P' AND [Agreement_ID] = 1
  ORDER BY [Supplier_Group_Name]";

$stmt = $pdo->prepare($_400p_1_1);
$stmt->execute();
$results1 = $stmt->fetchAll();

以下是引入信息的示例：

<label>Program ID:</label><input value="<?php echo $results1[0]['Program_ID'];?>" readonly>

我还应该提一下，page1.php中的下拉选项通过AJAX发送到查询和PDO语句所在的update.php，以及其他HTML / PHP代码。同样，如果我只使用一个查询和一个PDO语句，它的工作正常。
