Simple SQL for you SQL experts.
I have two fields (AccountNo, CheckNo). There can be more than 1 checkno that has the same value. It will have the same AccountNo. I would like a listing from mytable displaying AccountNo and CheckNo, as was as the count of how many times it exists.
Select Distinct AccountNo, CheckNo, Count(Distinct AccountNo, CheckNo) as Total
from MyTable

What you are after is GROUP BY
Select AccountNo, CheckNo, Count(*) as Total
from MyTable
group by AccountNo, CheckNo
