我有這個查詢...

select * from selection_value where id = 14702
14702
14704
14724

14808

現在我知道這行不通，我只是想知道按此順序獲取所有這些ID的數據的最佳方法是什么？

這可能嗎？

Answer 1

使用IN ：

SELECT * FROM selection_value WHERE id IN (14702, 14702, 14704, etc.) ORDER BY id

* 編輯：*

要保留您的特定訂單，請創建一個新表：

CREATE TABLE2 (id INT IDENTITY(1,1), id_number int)

在此表中，按照需要對數字進行排序的順序添加數字。 然后，您可以使用類似以下查詢的方式按特定順序提取ID：

SELECT selection_Value.* FROM selection_value JOIN Table2 ON selection_Value.id = table2.id_number ORDER BY Table2.id

Answer 2

您可以使派生表的值在一個列中匹配 ，而在另一列中它們的順序匹配 -將其聯接到表中並通過排序列進行排序。

  select *
    from (
         select 1 ord, 14702 value union all
         select 2, 14704 union all
         select 3, 14724 union all
         select 4, 14710 union all
         select 5, 14738
         ) x
    join selection_value t on t.id = x.value
order by ord;

Answer 3

使用帶有逗號分隔值的IN子句。

select * from selection_value where id IN (14702,14703, so on) ORDER BY ID

Answer 4

您的問題並不十分清楚，但也許：

SELECT * FROM selection_value 
WHERE id IN
      (SELECT id FROM table ORDER BY id ASC)

剛剛指出您的訂單（您的查詢是否需要從另一個表中提取數據？）：

select * from selection_value where id IN (14702,14702,14704,14724,14710,14738,14717,14719,14719,14738,14722,14721,14724,14725,14706,14730,14708,14731,14715,14708,14749,14752,14754,14755,14757,14795,14753,14760,14761,14759,14762,14763,14785,14764,14765,14785,14766,14768,14796,14771,14772,14774,14776,14764,14780,14781,14767,14784,14785,14786,14788,14789,14790,14791,14785,14772,14792,14796,14785,14797,14798,14799,14800,14802,14778,14803,14758,14765,14762,14781,14785,14786,14808,14793,14805,14807,14808)

Answer 5

只需將您的問題粘貼到notepad ++中，在正則表達式模式下執行以下搜索和替換操作即可：

• \\ r->''
• \\ n-> \\ nunion all \\ nselect * from selection_value，其中id =

瞧！
