SSIS package and using a Lookup tranformation

I am currently working on a SSIS package and using a Lookup tranformation to output a value.

Lookup transformation uses a custom query as follows but the query returns mulitple results.

select * from (SELECT Account_Main_Financial_Id,
Account_Main_Start_Code,
Account_Main_End_Code,
Account_Main_Financial_Level_Nbr
FROM cdr.Account_Main_Financial
WHERE Account_Main_Financial_Id > 0
AND current_usage_ind = 1
) [refTable]
WHERE 4390 BETWEEN [refTable].[Account_Main_Start_Code] AND [refTable].[Account_Main_End_Code]
AND [refTable].Account_Main_Financial_Level_Nbr =
( SELECT MAX(Account_Main_Financial_Level_Nbr) FROM cdr.Account_Main_Financial
WHERE [refTable].Account_Main_Financial_Id =Account_Main_Financial_Id )

Account_Main_Financial_Id Account_Main_Start_Code Account_Main_End_Code Account_Main_Financial_Level_Nbr
1 0 4999 2
2 0 9999 1
20 4000 4499 3
47 4390 4399 4

I tried to use a parameter to resolve this issue but parameters in a sub query are not permitted in the custom query?

select * from (SELECT Account_Main_Financial_Id,
Account_Main_Start_Code,
Account_Main_End_Code,
Account_Main_Financial_Level_Nbr
FROM cdr.Account_Main_Financial
WHERE Account_Main_Financial_Id > 0
AND current_usage_ind = 1
) [refTable]
WHERE ? BETWEEN [refTable].[Account_Main_Start_Code] AND [refTable].[Account_Main_End_Code]
AND [refTable].Account_Main_Financial_Level_Nbr =
( SELECT MAX(Account_Main_Financial_Level_Nbr) FROM cdr.Account_Main_Financial
WHERE ? BETWEEN [Account_Main_Start_Code] AND [Account_Main_End_Code] )

Esentially, I need to return the Max(Account_Main_Financial_Level_Nbr) so that only Account_Main_Financial_Id=47 is returned.

Unfortunately, its not 1=1 and there are multiple rows being returned. Is there an easier way to do this?

Many thanks in anticipation.

Something like this perhaps:

SELECT  a.Account_Main_Financial_Id,
        a.Account_Main_Start_Code,
        a.Account_Main_End_Code,
        d.Account_Main_Financial_Level_Nbr
FROM    cdr.Account_Main_Financial a
        INNER JOIN (SELECT  Account_Main_Financial_Id,
                            MAX(Account_Main_Financial_Level_Nbr) Account_Main_Financial_Level_Nbr
                    FROM    cdr.Account_Main_Financial
                    GROUP BY Account_Main_Financial_Id
                   ) d ON a.Account_Main_Financial_Id = d.Account_Main_Financial_Id
WHERE   a.Account_Main_Financial_Id > 0
        AND a.current_usage_ind = 1
        AND 4390 BETWEEN a.Account_Main_Start_Code AND a.Account_Main_End_Code

Thanks for your solution but when executing, still get multiple rows returned;

Account_Main_Financial_Id Account_Main_Start_Code Account_Main_End_Code Account_Main_Financial_Level_Nbr
1 0 4999 2
2 0 9999 1
20 4000 4499 3
47 4390 4399 4

If all you want is a single row returned then do something like this:

;WITH MyCTE AS (
    SELECT  Account_Main_Financial_Id,
            Account_Main_Start_Code,
            Account_Main_End_Code,
            Account_Main_Financial_Level_Nbr,
            ROW_NUMBER() OVER (ORDER BY Account_Main_Financial_Level_Nbr DESC) Row
    FROM    cdr.Account_Main_Financial a
    WHERE   Account_Main_Financial_Id > 0
            AND current_usage_ind = 1
            AND 4390 BETWEEN Account_Main_Start_Code AND Account_Main_End_Code
             )
SELECT  Account_Main_Financial_Id,
        Account_Main_Start_Code,
        Account_Main_End_Code,
        Account_Main_Financial_Level_Nbr
FROM    MyCTE
WHERE   Row = 1

That works a treat in Query Analyser but not in the SSIS Lookup Transformation; Advanced > Modify the SQL Statement.

Any way to incorporate this into the Lookup transformation?
