The problem with this is that the missing dates are, well, missing.
Maybe this will help get you started on your quest. Let me know if you
need the missing dates for certain or if these queries are incorrect.
Note: Most people in this newsgroup would argue against storing fStock
in tbl2 at all since it can be calculated.
