TSQL排序依据 - 硬编码值列表

Question

我有一个查询返回其他记录状态列。记录状态栏有多个值，如：“活动”，“删除”，等等

我需要按结果“活动”，然后选择“删除”，然后等...

我目前正在创建CTE来带来每一组记录，然后是UNION ALL。是否有更好的动态方法来完成查询？

谢谢

Answer 1

欲了解更多情况值，你可以这样做：

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

你可以在这里

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

使用CASE，但如果你有status更多的价值，并要排序Active然后DELETE

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

Answer 3

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
