If then else logic in transformer

[developeretl]

Hi,
I need to do transformation with if then else condition..... iam having input column with codes 1,2,3,4,5,6,7
I need to populate the " ab" if the input code 1,2,3 and if it is 4 ,5 then "cd" and if it is 6 ,7 then "ef"
i tried by writing if then else logic for every code. Can you please guide me with simple way of implementing the logic...

The simplest is writing the If Then Else with the output values that are related to less number of input columns.

Code: Select all

If InputColumn = 6 Or InputColumn = 7 Then 'ef' Else If InputColumn = 4 Or InputColumn = 5 Then 'cd' Else 'ab'

You can try something like

Code: Select all

If Index('|':yourField : '|', '|1|2|3|') > 0 Then 'ab' Else .......

Alternatively you can try

Code: Select all

If yourField > 5 Then 'ef' Else If yourField > 3 Then 'cd' .......

Code: Select all

Field("ab|ab|ab|cd|cd|ef|ef", "|", InLink.TheValue, 1)

Or use a lookup table in a Modify stage (lookup_string_from_int16() function).

... or just stick with the if-then-else logic posted.

Only other thing you might want to account for are values outside the 1-7 range. Justin Case.
