Hi
How do I solve this:
lets say I have a post code mapping files.
1 - 100 - Zone 1
101 - 200 - Zone 2 and so on.
Then I wanna add my input data that has a postalcode 75 - then it add's Zone 1 to that row.
Without having to do a join and then a filter... because i have millions of input rows and hundreds of mapping rows.
?
