Question

这是我的代码，它没有返回任何内容，我不知道如何处理这个案例...

Select distinct u.semail email, '' blank 
FROM user u inner join
     group g
     on u.hgroup=g.hmy
where u.binactiveuser = 0 and
      u.hgroup in (case when @application = 'Test1' then (Select hmy from group where ucode like 'pay%')
                          else case when @application = 'Test2' then (Select hmy from group where ucode in ('cc','vente','leas'))
                               else case when @application = 'Voy' then (Select hmy from group where ucode not like 'pay%' and ucode not in ('cc','vente','leas'))
                                    end
                               end
                     end)

我认为OR会起作用......

Select distinct u.semail email, '' blank 
FROM user u inner join
     group g
     on u.hgroup=g.hmy
where u.binactiveuser = 0 and
      (
       (@application = 'Test1' and u.hgroup in (select hmy from group where ucode like 'pay%'))
       or
       (@application = 'Test2' and u.hgroup in (Select hmy from group where ucode in ('cc','vente','leas')))
       or
       (@application = 'Voy' and u.hgroup in (Select hmy from group where ucode not like 'pay%' and ucode not in ('cc','vente','leas')))
      )

In和Case语句在Where中
