MySQL PDO UNION查詢，發現表的結果來自

Question

我試圖創建一個查詢，目前跨越三個表尋找各種ID的，但我需要知道什麼表的ID來自。

$searchQuery = 'LS7 2UP'; 

$stmt = $db->prepare(" 
SELECT id as 'nameSearchID' FROM user WHERE recordStatus=1 AND CONCAT(forename, ' ', surname) LIKE :nameSearch 
UNION ALL 
SELECT clientID AS 'salesOrderClientID' FROM salesOrder WHERE recordStatus=1 AND salesOrderID LIKE :salesOrderID 
UNION ALL 
SELECT id AS 'addressID' FROM address WHERE recordStatus=1 AND postcode LIKE :searchPostcode 
"); 

$stmt->bindValue(':nameSearch', "%$searchQuery%", PDO::PARAM_STR); 
$stmt->bindValue(':salesOrderID', "%$searchQuery%", PDO::PARAM_STR); 
$stmt->bindValue(':searchPostcode', "%$searchQuery%", PDO::PARAM_STR); 

$stmt->execute(); 
$rowCount = $stmt->rowCount(); 
$resultsOrig = $stmt->fetchAll(PDO::FETCH_ASSOC); 

此輸出2分的結果，其它是從地址表發現，但它示出從「用戶」表來。

任何想法？

Array 
(
    [0] => Array 
     (
      [nameSearchID] => 69e17996-93be-4562-ad55-49ac62801bba 
     ) 

    [1] => Array 
     (
      [nameSearchID] => 135e4e26-869d-44cc-b400-383e884923ea 
     ) 

)

其添加爲參數：

SELECT id as 'nameSearchID', "user" FROM user WHERE recordStatus=1 AND CONCAT(forename, ' ', surname) LIKE :nameSearch 
UNION ALL 
SELECT clientID AS 'salesOrderClientID', "salesOrder" FROM salesOrder WHERE recordStatus=1 AND salesOrderID LIKE :salesOrderID 
UNION ALL 
SELECT id AS 'addressID', "address" FROM address WHERE recordStatus=1 AND postcode LIKE :searchPostcode
