Hi,
I am trying to replace  the following  string pattern
0 0 0 0

Open in new window

with NULLs  in an SSIS Data Flow. In a Derived Column Transformation I have entered the following expression
[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)

Open in new window

but the pattern is still getting through.
Any help appreciated. Thanks

Here is  the input and output to the transformation task
and the expression in the task used to filter this column
[MSTUB-xInt_Only-Rev-Dt] == "00000000" || [MSTUB-xInt_Only-Rev-Dt] == "0 0 0 0" || [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)

tried this also, result is the same as above
[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)

USing TRIM solves the issue
TRIM([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)
