I would like your assistance in converting some if-statements into set analysis if possible.
if(fruit = 'Apple', sum(field1)+sum(field2),
Is something like this possible to refactor into set analysis?
If-statements are slow, and I'd like to make my app faster by moving it to set analysis.
Set analysis is used mostly for selection, not conditional logic. If you'd like to avoid nested IFs then I'd change your statement to:
Pick( WildMatch(fruit, 'Apple', 'Orange') + 1, (sum(field1)+sum(field2)+sum(field3)) * 3, sum(field1)+sum(field2), (sum(field1)+sum(field2)) * 2 )
Explanation: Pick returns 1 if apple, 2 if orange, 0 if not matched. Adding 1 will make it 2 if apple, 3 if orange, 1 if not matched. Pick will select the item corresponding to the 1, 2 or 3 result.
So, it's essentially the equivalent of a Case or Switch statement.
Hope this helps.
