I am a novice at working with queries and need some quick
help in getting a few queries for a project.
I have 3 primary fields that I will be working with
[CircuitID], [BillFromDate], [BillToDate].

I need queries that will pull overlaps in billing dates
for [CircuitID], gaps in billing dates for [CircuitID],
Ex. [CircuitID] BG4890X874 [BillFromDate] 3/1/03,
[BillToDate] 4/18/03
[CircuitID] BG4890X874 [BillFromDate] 4/1/03,
[BillToDate] 4/30/03
** [BillToDate] extended into April**

ex. [CircuitID] BG4890X874 [BillFromDate] 3/1/03,
[BillToDate] 3/31/03, [BillFromDate] 5/1/03, [BillToDate]
5/31/03. Missing billing for the Month of April.

I also need a query for will find the date range between
[BillFromDate] and [BillToDate] days more than 30 days
per billing period.
Ex. 4/1/03 - 5/15/03 45
Thank you
 
You might try queries whose SQL looks something like those embedded below.
