sql server use computed column

Is there a way to do this:

select Name, 
    (SELECT Max(reference) 
        from Rematch 
        WHERE Gender='M' and convert(varchar,getdate,103) = '08/10/2012'
    ) As MaxReferenceMale, 
    (SELECT Max(reference) 
        from Rematch 
        WHERE Gender='F' and convert(varchar,getdate,103) = '08/10/2012'
    ) As MaxReferenceFemale
WHERE (Gender='M' and Reference > MaxReferenceMale) Or 
    (Gender='F' and Reference > MaxReferenceFemale)

I realise there may be better ways of writing the query. Is it possible to refer to MaxReferenceFemale and MaxReferenceMale in the WHERE clause?

Answer 1

Stick a

SELECT * FROM (...) WHERE ...

around your query. You can use the aliased columns in your WHERE clause once it’s on the inside of the outer SELECT.
