I think this should be a simple query but I am not getting the results I am looking for.
I have two tables, each with a single column of data containing Purchase Order numbers.
I need to find if a number exists in the first table but not in the second table.
The query I used was:
Select PONUM
from PS,AV
where PS.PONUM <> AV.PONUM
I basically end up with all of the rows from PS.PONUM
I am an ACCESS novice. I can do this in Excel but the number of rows (160000) is too much to handle in Excel.
