MySQL PDO UNION 쿼리에서 결과가 나온 테이블을 찾습니다

Question

현재 다양한 ID를 찾고있는 세 테이블에 걸쳐있는 쿼리를 만들려고합니다.하지만 ID가 어떤 테이블에서 왔는지 알아야합니다.

$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); 

이는 어드레스 테이블 찾는 2 개 결과를 출력하지만 '사용자'표 으로 나타낸 것.

아이디어가 있으십니까?

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

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

)

매개 변수로 추가

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
