如何在查询中反转通过/失败状态列？

Question

我有一张桌子：

sid   sname   status
101    abc    pass
102    cda    fail
103    fgh    pass
104    hij    pass
105    jqk    fail
106    lfj    fail

我希望输出为：

sid   sname   status
101    abc    fail
102    cda    pass
103    fgh    fail
104    hij    fail
105    jqk    pass
106    lfj    pass

Answer 1

select 
    sid, 
    sname,
    case
        when status = 'pass' then 'fail'
        when status = 'fail' then 'pass'
        else null
    end as 'status'
from tableX

Answer 2

UPDATE Table
SET Status = CASE Status WHEN 'pass' THEN 'fail' ELSE 'pass' END
GO
SELECT *
FROM Table
GO

或者：

UPDATE Table
SET Gender = IIF(Gender = 'pass', 'fail', 'pass')
GO
SELECT *
FROM Table
GO
