Question

I want to calculate a boolean expression like this

((('a' or 'b') AND ('c' or 'd') AND ('e' or 'f')) IN (SELECT COLUMN1 FROM...))

(‘a’, ‘b’… are all strings)

Of course if I write a query like that, SQL Server will throw error because ‘a’, ‘b’… are not boolean type.

Can anyone help me to write a shorter query to calculate that expression than below one:

((('a' in (select..)) or (('b' in (select...)))
AND ((('c' in (select..)) or (('d' in (select...)))
AND ((('e' in (select..)) or (('f' in (select...)))

Thanks.

`EDIT: add more infor about my query`

This is my query (of course it didnot work)

SELECT ID, Name, Addr, PhoneNumber, Descr FROM CusInfo 
WHERE Type_ID = 'type_01' 
AND `((('a' or 'b') AND ('c' or 'd') AND ( 'e' or 'f')) IN (SELECT Cri_ID FROM CusCri WHERE CusCri.Cus_ID = CusInfo.ID))`

All I want is to calculate (('a' or 'b') AND ('c' or 'd') AND ( 'e' or 'f')) IN (SELECT Cri_ID FROM CusCri WHERE CusCri.Cus_ID = CusInfo.ID) as a boolean.

Try (updated, following amended question):

SELECT ID, Name, Addr, PhoneNumber, Descr FROM CusInfo i
WHERE Type_ID = 'type_01' AND 
      3 = (select count(distinct case when c.Cri_ID in ('a','b') then 1
                                      when c.Cri_ID in ('c','d') then 2
                                      when c.Cri_ID in ('e','f') then 3
                                 end)
           from CusCri c
           WHERE c.Cus_ID = i.ID and c.Cri_ID in ('a','b','c','d','e','f') )
