I am trying to find duplicate statements that are entered in 1 month but the data entry may be off a day.  
Example: Statement Dates are 01/31/14, 02/28/14, 02/28/14, 03/30/14
          or  Statement Dates are 01/31/14, 02/28/14, 03/05/14, 03/30/14

I should only have 1 statement a month.  I wanted to try to create a field to convert the statement date to Month format, then look for duplicates in the month.

Fields:  
AccountID (Account Number)
StatementDate (Statement Date)

I tried:
Expr1: Format([StatementDate],"mmm")

try this query

select AccountID,Count(Format([StatementDate],"yyyymm")) As Expr1,Count(Format([StatementDate],"yyyymm")) As expr2
from tableName
where Count(Format([StatementDate],"yyyymm"))>1
Group by AccountID,Count(Format([StatementDate],"yyyymm"))


or

select AccountID,Count(Format([StatementDate],"yyyymm")) As Expr1,Count(Format([StatementDate],"yyyymm")) As expr2
from tableName
Group by AccountID,Count(Format([StatementDate],"yyyymm"))
having Count(Format([StatementDate],"yyyymm"))>1

from tableName
where Count(Format([StatementDate],"yyyymm"))>1
Group by AccountID, Format([StatementDate],"yyyymm")


or

select AccountID,Count(Format([StatementDate],"yyyymm")) As Expr1,Count(Format([StatementDate],"yyyymm")) As expr2

The first one had "Cannot have aggregate function in WHERE clause (Count(Format([StatementDate],"yyyymm"))>1

The second one worked, thanks.

The results give me the # of statements in expr1 and expr2:

AccountID      Expr1      Expr2
125555                  3               3
567891               2          2


Is there a way to show the Month duplicated or should I just hide 1 of the fields?
