TSQL排序依據 - 硬編碼值列表

Question

我有一個查詢返回其他記錄狀態列。記錄狀態欄有多個值，如：「活動」，「刪除」，等等

我需要按結果「活動」，然後選擇「刪除」，然後等...

我目前正在創建CTE來帶來每一組記錄，然後是UNION ALL。是否有更好的動態方法來完成查詢？

謝謝

Answer 1

欲瞭解更多情況值，你可以這樣做：

WITH StatusOrders 
AS 
(
    SELECT StatusOrderID, StatusName 
    FROM (VALUES(1, 'Active'), 
       (2, 'Deleted'), 
       ... 
       n, 'last status')) AS Statuses(StatusOrderID, StatusName) 
) 
SELECT * 
FROM YourTable t 
INNER JOIN StatusOrders s ON t.StatusName = s.StatusName 
ORDER BY s.StatusOrderID; 

Answer 2

你可以在這裏

ORDER BY CASE WHEN Status = 'Active' THEN 0 ELSE 1 END ASC 

使用CASE，但如果你有status更多的價值，並要排序Active然後DELETE

ORDER BY CASE WHEN Status = 'Active' THEN 0 
       WHEN Status = 'Deleted' THEN 1 
       ELSE 2 
     END ASC

WITH 
cteRiskStatus 
AS 
(
SELECT RiskStatusID, RiskStatusName 
FROM (VALUES(1, 'Active'), 
       (2, 'Draft'), 
       (3, 'Occured'), 
       (4, 'Escalated'), 
       (5, 'Closed'), 
       (6, 'Expired'), 
       (7, 'Deleted')) AS RiskStatuses(RiskStatusID, RiskStatusName) 
) 
SELECT * FROM cteRiskStatus
