Need Expert Query Help
I need helping writing a query that I have had to write anything like before.
I have a table where I have to loop through the records and write out values where certain conditions are missing.
I am comparing the value of 2 fields in TableA with the Values of 2 Fields in TableB. IF there is a record in TableA that does not have both fields match to TableB then write out a row
Example below
TableA
Fields= AccountNumber,Month,Year
TableB
Field = Month,Year
if there is a record in TableA where TableA.Month <> TableB.Month AND TableA.Year<>TableB.Year then write out the TableA.AccountNumber
I thought this would be simple, but I am not getting the results I am looking for. Any experts out there to help would be greatly appreciated as I am new to learning about complex query writing.
Thanks so much

You will have to join tables on AccountNumber and compare the two conditions on Month,Year.
select * from a
join b
on a.accountnumber=b.accountnumber
where A.Month <> B.Month AND A.Year<>B.Year
