选择sql server的语句

Question

您好我需要从列中获取两种类型的值，该语句应显示如下，

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

为Successful和

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

为Failed，每个按datename(mm, date)排序。

有人可以帮助我如何使这两个陈述在同一个声明中运行吗？

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)

如果您需要单独列中的值，请使用：

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]
