Editing a Derived Column Transformation Expressions in SSIS  2008 r2 SSIS package

Hi,
I have the following Derived Column Expression in a  Data Flow Transformation in an SSIS package
[MSTUB-xInt_Only-Rev-Dt] == "00000000" ? NULL(DT_WSTR,10) : SUBSTRING([MSTUB-xInt_Only-Rev-Dt],5,4) + "-" + SUBSTRING([MSTUB-xInt_Only-Rev-Dt],3,2) + "-" + SUBSTRING([MSTUB-xInt_Only-Rev-Dt],1,2)

Open in new window

This (I THINK)  replaces  values == "00000000" with NULLs
I now want to filter out “0 0 0 0” values also.
How do I amend the expression to accommodate this? Is it possible to add some kind of “OR”  to it?
Any guidance appreciated, thanks

Is it possible to add some kind of “OR”  to it?

That's indeed possible.  The OR in SSIS expressions is a double pipe: ||

So your expression would be something like this:

[MSTUB-xInt_Only-Rev-Dt] == "00000000" || [MSTUB-xInt_Only-Rev-Dt] == "0 0 0 0" ? NULL(DT_WSTR,10) : SUBSTRING([MSTUB-xInt_Only-Rev-Dt],5,4) + "-" + SUBSTRING([MSTUB-xInt_Only-Rev-Dt],3,2) + "-" + SUBSTRING([MSTUB-xInt_Only-Rev-Dt],1,2)
