为SQL Server Select语句

Question

你好，我需要从一列得到两种类型的值，该声明应显示为遵循，

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

为Successful和

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

为Failed，每一个订购datename(mm, date)。

有人可以帮助我如何使这两个陈述在同一个陈述中运行吗？

Answer 1

试试这个：

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

如果您需要在单独的列值，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]
