SQL count statement

Table DIPApplication has 'x' records -- and
Agent_ID can be represented in many of these records, i.e. Data Entry ser stamp in record.
want to be able to produce a sql result where I can return:

[Agent_ID], [how many times DIPProcessed] from Sept 1st 2009

e.g. how many records that have DIPProcessed=1 associated with Agent_ID from Sept 1st 2009

list all unique Agent_ID's in table, along with the sum of their respective DIPProcessed

how do I write this type of query please?

Table:  DIPApplication  
Agent Ref.:  Agent_ID  (various int id's)
DIP Processed:   DIPProcessed = 1 (means processed)
DateTime:  DateTimeStamp  (DateTime)

(using SQL Server Management Studio interface)

I can get the entire number of DIP's Processed as follows:

SELECT COUNT(*)
FROM DIPApplication
WHERE DIPProcessed=1

Just need to expand this query as described above.

you mean:
SELECT Agent_ID  , COUNT(*) 
FROM DIPApplication
WHERE DIPProcessed=1
group by Agent_ID

angelIII: yes, excellent 100% correct results.  thank you.

could I ask please 1 more thing related to above -- if I want to cross-reference that with another table.  i.e. to retrieve the Agent's name instead of just Agent_ID number value (more meaninful when reading)


Table: StaffMember
Agent_ID [int]
Agent Name: DisplayName  [nvarchar]

SELECT app.Agent_ID , a.displayname , COUNT(*) 
FROM DIPApplication app
JOIN agent a
  on a.agent_id = app.agent_id
WHERE app.DIPProcessed=1
  and app.DateTimeStamp >= convert(datetime, '2008-09-01', 120)
