how to use convert for an alias name of column in case statement

    Hi experts,

    In the below case statement, the Salespersonflag column is being returned. when i use this case statement in a select and use that statement in a SSIS package i see the output column datatype for salespersonflag is DT_14. I want the case statement to return a DT_BOOL which is a bit datatype. can any one help me?

    CASE

    WHEN sp.[SalesPersonID] IS NULL THEN cast(0 as bit)

    ELSE cast(1 as bit)

    END AS [SalesPersonFlag]

    I have tried the below options but did not work.

    1. use cast/convert to the entire case statement.

    2. using cast for 1 and 0 values that are being shown as above.

    But the end result shown is as DT_14 in my package metadata. Appreciate your inputs on how to get the case statement returning a bit value.

    Thanks

    CAST(CASE

    WHEN sp.[SalesPersonID] IS NULL THEN 0

    ELSE 1

    END AS BIT)AS [SalesPersonFlag]
