So i am trying to convert some of my searches from joins to appendcol to improve performance but I am running into some problems.
I can't figure out how to create a table in this question- so just read the first row like Field=A, Baseline=100, Week1=103, Week2=105
Field Baseline Week1 Week2
A 100 103 105
B 50 54 56
C 20
Originally- I was using join to pull in baseline because baseline is based on historical trends, while week1 and week2 are the most recent weeks. To improve performance- I want to change to using something else, but when I use appendcol- field value C is pulled in based on the historical baseline even when they don't have values in week1 and week2.
I only want to display the baseline for A and B because they have data in week1/2. Is there anyway to control this with appendcols?
This is a very simplified example so I need a somewhat generic solution or idea.
Thanks for the help!
