Compare this month's data to last month's

Tags: Microsoft, SQL Server, 2005
Hi Experts,

I am in the process of creating a query in SQL Server Mgt. Studio ( SQL Server 2005 ).  I am trying to compare accounts gathered from certain criteria for the current month and the previous month and I only want the records not found in the previous month's subset.  The code below attempts to do this, but the subquery at the bottom returns more than one row.  The spec I have been given will ultimately move to production with no parameters and must be done in one query.   I have also determined that subtracting 1 day from the field last_stmt_date gives me the last day of the previous month, which is the stmt_date I will use to get last months' data.  Thanks.

Scott
