SQL Server - IN clause with multiple fields

Question

Is it possible to include in a IN clause multiple fields? Something like the following:

select * from user
where code, userType in ( select code         


        

Answer 1

How about this instead:

SELECT user.* FROM user JOIN userType on user.code = userType.code AND user.userType = userType.userType

Answer 2

select * from user
where (code, userType) in ( select code, userType from userType );

Answer 3

I don't think that query is quite portable,it would be safer to use something like

select * from user
where code in ( select code from userType ) and userType in (select userType from userType)

Answer 4

Only with something horrific, like

select * from user
where (code + userType) in ( select code + userType from userType )

Then you have to manage nulls and concatenating numbers rather than adding them, and casting, and a code of 12 and a usertype of 3 vs a code of 1 and a usertype of 23, and...

So there ya go: a solution that doesn't use joins or exists.. and a bunch of reasons why you shouldn't use it ;)

Answer 5

You could use a form like this:

select * from user u
where exists (select 1 from userType ut
              where u.code = ut.code
                and u.userType = ut.userType)

Answer 6

I had to do something very similar but EXISTS didn't work in my situation. Here is what worked for me:

UPDATE tempFinalTbl
SET BillStatus = 'Non-Compliant'
WHERE ENTCustomerNo IN ( SELECT DISTINCT CustNmbr
             FROM tempDetailTbl dtl
            WHERE dtl.[Billing Status] = 'NEEDS FURTHER REVIEW'
              AND dtl.CustNmbr = ENTCustomerNo 
              AND dtl.[Service] = [Service]) 
  AND [Service] IN  ( SELECT DISTINCT [Service] 
             FROM tempDetailTbl dtl
            WHERE dtl.[Billing Status] = 'NEEDS FURTHER REVIEW'
              AND dtl.CustNmbr = ENTCustomerNo 
              AND dtl.[Service] = [Service]) 

EDIT: Now that I look, this is very close to @v1v3kn's answer
