How can I reference records outside the two date parameters?

Question

Hi all,
I have a query that fetches records based on the two date parameters defined (Startdate and Enddate).
If the Startdate is 2014-12-01 and the Enddate is 2014-12-12, I want to pull records outside these two date parameters, that is      2014-09-01 and 2014-11-30.
I want to add up the records from  2014-09-01 and 2014-11-30 and include them in one of the columns in my report.
I tried using this query:
 SUM(CASE WHEN FilteredIncident.Statuscodename IN ('QUEUED', 'ASSIGNED') AND (EnteredOn >= '2014-09-01' AND EnteredOn<= @StartDate) THEN 1 ELSE 0 END) AS OpenRecords
Please help with any ideas..thanks

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you probably need to read and download the PDF for:

There is no such crap as a “status_code_name” in RDBMS. It has to be a “<something in particular>_status”; think about how silly that data element name is! Want to keep going and have a “status_code_name_value_id”? LOL! 
The name “Filtered_Incident” is also wrong. Tables are sets, so unless you have only one element in this set, the table name should be a plural or (better) collective name. But a better question is why  did you split out “Filtered_Incidents” from “Incidents”?
Would you also split “Male_Personnel” and “Male_Personnel” from “Personnel”? 
Get a book on data modeling and learn some basics.

Having no DDL and no sample data makes this hard. Does your boss make you program without any documentation, DDL, etc? This spec is vague; you say to do a total, but show a count, etc. 
One of the many nice things about DATE data types is that the BETWEEN predicate works with them, so you can quite writing 1960's BASIC predicates with primitive logic operators. 
Here is a guess: 
SELECT SUM(CASE WHEN incident_date BETWEEN '2014-09-01' 
           AND @report_start_date THEN 1 ELSE 0 END)
       AS open_record_cnt 
  FROM Incidents
 WHERE incident_status IN ('QUEUED', 'ASSIGNED')
    AND incident_date <= @report_end_date;
