SELECTING A CASE VALUE ???

  • Hi

    I am using the following to retrive a clients "secure" name if alias-type of 004 exists.

    Problem I have is if the client has more than one alias type(001,002, 003) they all show up

    What I need to do is if a client has an alias code of 004 then use that no matter how many they have

    if they don't have an oo4 and have multiple say 003's then use the client name ..

    Thanks

    SELECT CASE

    WHEN at.CODE = '004'

    THEN a.FName + ' ' + isnull(a.MName, '') + ' ' + + a.lname

    ELSE c.FName + ' ' + ISNULL(c.MName, '') + ' ' + c.LName

    END AS Tag_Data

    FROM Client AS C

    LEFT JOIN

    -- Note the order of the clausing here. It causes an

    -- inner join to the rest of the tables BEFORE the

    -- outer join is included.

    Client_To_Alias_Collection AS AC

    INNER JOIN Alias AS A

    ON AC.OID_Link = A.OID

    INNER JOIN Alias_Type AS AT

    ON AT.OID = A.Alias_Type_Moniker

    ON c.oid = ac.oid

    AND A.EXPDate IS NULL WHERE c.OID = '12345'

  • Not much in the way of details to work with here. I took a shot in the dark. See if this gets you close.

    select * from

    (

    select ROW_NUMBER() over(partition by c.ClientID order by case when at.CODE = '004' then 1 else 0 end) as RowNum,

    CASE

    WHEN at.CODE = '004'

    THEN a.FName + ' ' + isnull(a.MName, '') + ' ' + + a.lname

    ELSE c.FName + ' ' + ISNULL(c.MName, '') + ' ' + c.LName

    END AS Tag_Data

    FROM Client AS C

    LEFT JOIN

    -- Note the order of the clausing here. It causes an

    -- inner join to the rest of the tables BEFORE the

    -- outer join is included.

    Client_To_Alias_Collection AS AC

    INNER JOIN Alias AS A

    ON AC.OID_Link = A.OID

    INNER JOIN Alias_Type AS AT

    ON AT.OID = A.Alias_Type_Moniker

    ON c.oid = ac.oid

    AND A.EXPDate IS NULL WHERE c.OID = '12345'

    ) x

    where x.RowNum = 1
