SSIS - Filter rows *and* add columns in script component

    Is it possible to have a transformation script component which filters rows as well as adding new output columns?

    I have a script component with "Output 0":

    • Exclusion Group = 1
    • SynchronousInputID = Script Component.Inputs[Input 0]
    • 2 x additional columns

    In my code I have:

    Row.newcol1 = "Value 1";
    Row.newcol2 = "Value 2";

    if (Row.oldcol1.Length <= 20)
    {
        Row.DirectRowToOutput0();
    }

    But I'm getting the errors:

    CS0229	Ambiguity between 'Input0Buffer.newcol1' and 'Input0Buffer.newcol1'
    CS0229	Ambiguity between 'Input0Buffer.newcol2' and 'Input0Buffer.newcol2'

    So I can filter rows *without* adding new columns and I can add new columns *without* filtering data.

    Is there a way to add columns *and* filter data without having to create a new set of output columns and copying over the inputs to the outputs?

    I don't know the answer, but may have an alternative solution.

    Use a Conditional Split to redirect rows which you do not want, by sending them to an unused output.

    Your Script Component can be simplified once this is in place.

    If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.
