Hi All,

Needed a logic in transformer for the below scenario. i shouldn't use pivot stage. and needed in datastage and not using unix.

I/P data:
Account_numb Name Total
123 ABCDEF 123456789
345 GHIJKLMN 987654321

O/P data:
Account_numb Name Total
123 AB 123
123 CD 456
123 EF 789
345 GH 987
345 IJ 654
345 KL 321
345 MN NULL

Thanks in Advance,

Try using loop variables (if you are on 8.5 or above version of datastage) in the transformer stage to get the required output

You could try looping option in transformer stage to convert every single row to multiple rows based on our requirement.

You could use @ITERATION <= 3 as looping condition.

Thanks

Is there any logic without @Iteration and looping functions. can we implement using stage variables?

Thanks

What have YOU tried?

What are your Business Requirements? Specifically wondering about the rules for the "Name" and "Total" field chopping up you seem to be doing but that's always a hard call to make when someone posts completely made up "example" data with no requirements. Right now it doesn't make all that much sense - every two characters from Name match up to three characters of Total?

And as asked before, what have you tried so far? What issues are you facing?

i'm not sure on approach. trying to see anything can be done

Put three constraint links in transformer for 123,456,789...Then funnel them into one link with three records.

Why 3? I don't see anything that notes it will always / only be three, matter of fact the second set of data shows 4 occurrences.

Fine. Again - what are your Business Requirements / transformation rules? Explain in words how to perform the splitting of the two columns so that people can stop guessing what you need done.

You have to divide the data based on constraints. These should be as many as the maximum number of divisions. So if there are 4 maximum rows then 4 constraints. Then funnel these constraint links to collect them into rows.

Hi HemaV,

The scenario can be solved by using loop variable.

In iteration-

@ITERATION <= Len(Reference.col2) /2

Take 2 loop variables-
Derivation LoopVariable
If @ITERATION <=1 Then LV1 Else LV1 +2 LV1(initialize with 2)

If @ITERATION <=1 Then LV2 Else LV2 +3 LV2(initialize with 3)

Output Derivation-

Derivation ColName

Col1 Col1
Right(Left(Reference.col2, LV1),2) Col2
If len(StripWhiteSpace(Right(Left(Reference.col3, LV2),3))) <3 Then "" Else Right(Left(Reference.col3, LV2),3) Col3

Sounds fun. How many guesses are we allowed? Is there a prize?

Oh yes... a very special prize. <wink,wink>
