LEFT JOIN RegMem
ON Members.MemID = RegMem.MemID
WHERE SDate = #" & Format(dteSDate, "yyyy-mm-dd") & "#;"
I'm assuming that you are using Access...
LEFT JOIN is the one that selects everything from the first table and just the records from the second table with the matching field specified, right?
What's the difference between an INNER and OUTER JOIN?
I am using access. I didn't know you could use functions like IIF and IsNull in statements like that. I'll give it a try - thanks.
