如何從3個表中的部分列數據訂購mysql查詢輸出

Question

本質上，我正在嘗試使用上述列中的數據，將所有3個表中的Driver數據連接到一個通過regex通過mysql組織的輸出查詢中。

我要解決的問題與我的輸出數據的排序有關。 例如：我有3個表，這3個表中的每一個都有一個稱為driver的列，具有相同的數據。 區別在於驅動程序列中的“驅動程序/索引”。

借助這些數據，我計划將單據和客戶信息重新安排給喜歡的駕駛員。
例如

表|列|數據
DeliverySlip [驅動程序]（kevin / 1）
PickupSlip [驅動程序]（kevin / 3）
NewCustInfo [驅動程序]（kevin / 2）

---

輸出應為：

1. 送貨單
2. NewCustInfo
3. PickupSlip

代替：

1. 送貨單
2. PickupSlip
3. NewCustInfo

---

我的代碼：

$driverget1="Kevin/1"; // this is grabbed through an SQL SELECT statement
$drivername=explode($driverget1,"/");
$tablearray2 = "DeliverySlip|PickupSlip|NewCustInfo";
$table2 = explode("|", $tablearray2);
$Query = "SELECT * FROM `bwa1`.`$table2[0]`,`bwa1`.`$table2[1]`,`bwa1`.`$table2[2]` WHERE `Driver` REGEXP '{$drivername[0]}/' AND `Accomplished`='0' ORDER BY `Driver` REGEXP '/[[:digit:]]' ASC";

當然我得到一個模棱兩可的錯誤。 因此，我正在考慮使用JOIN語句。 但是從我的理解來看，這似乎只是聯接列而不是表。 我只想根據NAME / INDEX對驅動程序進行排序，而忽略了我從3個不同的表中獲取信息的事實。 排序此數據的最佳方法是什么？

更新：

我開始和UNION一起玩耍，這就是我想要的。 下面的例子：

SELECT * FROM 
(
  SELECT NewCustInfo.Driver,NewCustInfo.id,NewCustInfo.Accomplished 
        FROM NewCustInfo WHERE NewCustInfo.Driver 
        REGEXP 'Test123/' AND NewCustInfo.Accomplished='0' 
        ORDER BY NewCustInfo.Driver REGEXP '/[[:digit:]]' ASC
) DUMMY_ALIAS1

UNION ALL

SELECT * FROM 
( 
  SELECT PickupSlip.Driver,PickupSlip.id,PickupSlip.Accomplished 
        FROM PickupSlip WHERE PickupSlip.Driver 
        REGEXP 'Test123/' AND PickupSlip.Accomplished='0' 
        ORDER BY PickupSlip.Driver REGEXP '/[[:digit:]]' ASC
) DUMMY_ALIAS2

UNION ALL

SELECT * FROM 
( 
  SELECT DeliverySlip.Driver,DeliverySlip.id,DeliverySlip.Accomplished 
        FROM DeliverySlip WHERE DeliverySlip.Driver 
        REGEXP 'Test123/' AND DeliverySlip.Accomplished='0' 
        ORDER BY DeliverySlip.Driver REGEXP '/[[:digit:]]' ASC
) DUMMY_ALIAS3

我仍然需要弄清楚每個項目最初是從哪張桌子來的。 我唯一能想到的就是將表名插入Driver列，並用定界符將其分隔，以便可以進行REGEXP處理。

Answer 1

像這樣在選擇中添加表名如何：

SELECT * FROM  
(  
    SELECT NewCustInfo.Driver,NewCustInfo.id,NewCustInfo.Accomplished,'NewCustInfo' as tbname
    FROM NewCustInfo WHERE NewCustInfo.Driver 
    REGEXP 'Test123/' AND NewCustInfo.Accomplished='0' 
    ORDER BY NewCustInfo.Driver REGEXP '/[[:digit:]]' ASC
) DUMMY_ALIAS1

UNION ALL

SELECT * FROM 
( 
    SELECT PickupSlip.Driver,PickupSlip.id,PickupSlip.Accomplished,'PickupSlip' as tbname
    FROM PickupSlip WHERE PickupSlip.Driver 
    REGEXP 'Test123/' AND PickupSlip.Accomplished='0' 
    ORDER BY PickupSlip.Driver REGEXP '/[[:digit:]]' ASC
) DUMMY_ALIAS2

UNION ALL

SELECT * FROM 
( 
    SELECT DeliverySlip.Driver,DeliverySlip.id,DeliverySlip.Accomplished,'DeliveryShip' as tbname
    FROM DeliverySlip WHERE DeliverySlip.Driver 
    REGEXP 'Test123/' AND DeliverySlip.Accomplished='0' 
    ORDER BY DeliverySlip.Driver REGEXP '/[[:digit:]]' ASC
) DUMMY_ALIAS3

Answer 2

SELECT * FROM (SELECT PickupSlip.Driver, 
SUBSTRING_INDEX(PickupSlip.Driver, '/', -1) AS orderindex, 
SUBSTRING_INDEX(PickupSlip.Driver, '/', 1) AS thedriver,
WHERE PickupSlip.Driver 
REGEXP '{$driverget1}/' 
AND PickupSlip.Accomplished='0') DUMMY_ALIAS1
ORDER BY (orderindex+0) ASC

這是我確定的代碼。
