Validation

Hi everybody, I am extracting two columns named SAMPLE_ID and TEST from an oracle table. Now i need to do a validation based on the condition:
If SAMPLE_ID<>Previous_SAMPLEID or TEST<>PREVIOUS_TEST Then
Sequence=0 Else Sequence=Sequence+1.
Sequence will be a new column which i have to generate. Now, can you guys let me know as to how i should deal with the If statement above. Do i need to write a subroutine?
Thanks

Add Five stage variables
Code: Select all
samplVar1(definition)- If LINK.SAMPLEID = samplVAR2 then 1 else 0
samplVar2(definition)- LINK.SAMPLEID
testVar1(definition)- If LINK.TEST = testVar2 then 1 else 0
testVar2(definition) - LINK.TEST
sequence (definition) - If samplVar1 = 0 or samplVar2 = 0 then 0 else sequence+1

You could also explore "RowProcCompareWithPreviousValue" routine to achieve it.

As you want to remember the past value of sequence better to write a subroutine :
Please send a test data, I want to know the column position in your file

No routine is required in this case. This scenario can be handled perfectly and Krazykoolrohit gave a demo on that.
If your absolutely have to use a routine, then go for narasimha's suggestion. No need to re-invent the wheel.
My 2 centy!

On the lighther side, if weels have not been re-invented we would have struck with

Very funny ganesh123. Thats not called re-invention. Thats called enhancement.

Re-invention is alwayz done for Enhancement purpose only.

Hi all thanks much for the solution and suggestions. It is not absolutely necessary for me to use the necessary subroutine. KrazyKoolRohit's idea did work excellently.
Thanks once again :D
