SQL Exclude Field from GROUP BY in results but use in WHERE - tsql

Question

Pretty simple table:
CREATE TABLE [dbo].[Recognitions](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Submitter_CH_id] [int] NULL,
[Submitter_Last_Name] [varchar](50) NULL,
[Submit_Date] [datetime] NULL,
Submitter_CH_id Submitter_Last_Name Submit_Date
50 Prokupek 2014-04-01 00:00:00.000
50 Prokupek 2014-04-07 00:00:00.000
50 Prokupek 2014-04-01 00:00:00.000
50 Prokupek 2014-04-07 00:00:00.000
215 Conklin 2014-04-07 00:00:00.000
215 Conklin 2014-04-07 00:00:00.000
130 Catron 2014-04-07 00:00:00.000
136 Jardee 2014-04-07 00:00:00.000
247 Emken 2014-04-07 00:00:00.000
What I need to do is get a count of all the submissions made with in a certain date range grouped by recipient_ch_id. My app allows the user to enter the date range, so it needs to be part of the query results for my app to use it.
I need the results to be grouped by Submitter_CH_id. So something like this:
SELECT TOP (100) PERCENT Submitter_CH_id, Submitter_First_Name, Submitter_Last_Name, Submitter_Email, Submitter_Department,
Submit_Date AS [Last Submit], COUNT(Submitter_CH_id) AS [Total Submit]
FROM dbo.Recognitions
GROUP BY Submitter_First_Name, Submitter_Last_Name, Submitter_Email, Submitter_Department, Submitter_CH_id, Submit_Date
ORDER BY Submitter_CH_id
What I would like is the following:
Submitter_CH_ID Submitter_Last_Name Total Submissions
50 Prokupek 4
215 Conklin 2
130 Catron 1
... but because I also have to include Submit_Date in my GROUP BY the results instead show the count per ID per unique date (which it has to of course), so I get something like this:
Submitter_CH_ID Submitter_Last_Name Total Submissions
50 Prokupek 2
50 Prokupek 2
215 Conklin 1
215 Conklin 1
130 Catron 1
Any thoughts? This is MS SQL 2008. Thanks very much.

Answer 1

use a sub query.... like this:
select Submitter_CH_ID, Submitter_Last_Name, count(ID) AS [Total Submissions]
from (
select ID, Submitter_CH_ID, Submitter_Last_Name
from dbo.Recognitions
where date >= #start_date and date <= #end_date
) T
GROUP BY Submitter_CH_ID, Submitter_Last_Name
yay sub-queries!

Answer 2

I am guessing that you feel that you need Submit_Date in the GROUP BY clause because you're including it in the SELECT clause, because you're filtering by this value in the returned results. If that's correct, you can delete the field from your SELECT and GROUP BY lists if you instead filter in this query:
SELECT
Submitter_CH_ID, Submitter_Last_Name, COUNT(*) AS Submissions
FROM
Recognitions
WHERE
Submit_Date BETWEEN #StartDate AND #EndDate
GROUP BY
Submitter_CH_ID, Submitter_Last_Name
ORDER BY
Submitter_CH_ID
