I have a left table and a right table. I'm left joined on field X. I want all field X values and if there isn't a corresponding field X value in the right table, then I want nulls. I have 3 where clauses on the right table, but I included "Or Is Null" on each of them. This has always worked 100% fine when I've done it in other DBs, but for some reason it's not working here. One of the criteria is based on a field from a form, but as I said, I've used this identical logic before and it works fine. Anyone every encounter something similar? Thanks in advanced.
