爲SQL Server Select語句

Question

你好，我需要從一列得到兩種類型的值，該聲明應顯示爲遵循，

Select bid-id 
from bid 
where status = 'Expired' 

爲Successful和

Select bid-id 
from bid 
where status ='Unsold' 

爲Failed，每一個訂購datename(mm, date)。

有人可以幫助我如何使這兩個陳述在同一個陳述中運行嗎？

Answer 1

試試這個：

SELECT 
[bid-id], 
CASE WHEN Status = 'Expired' THEN 
    'Successful' 
WHEN Status = 'Unsold' THEN 
    'Failed' 
END AS [Status] 
FROM 
    [bid] 
ORDER BY datename(mm, date) 

如果您需要在單獨的列值，使用：

SELECT 
(SELECT [Bid-id] FROM [bid] WHERE Status = 'Expired' ORDER BY datename(mm, date)) AS [Successful], 
(SELECT [Bid-id] FROM [bid] WHERE Status = 'Unsold' ORDER BY datename(mm, date)) AS [Failed] 
FROM 
[Bid]
