Using aggregate rollup data

I am using a query for totals using group by with roll up.  The query looks like this:

SELECT COALESCE(CAST(A.TopicID AS varchar(2000)), 'Report Total:') as 'Conference', COUNT(*) AS 'Number of Entries', A.TopicName, SUM(A.Amount) AS Sum FROM vwApplication A INNER JOIN Topic B ON A.Topic = B.Topic INNER JOIN ConfCity C ON B.ConfCityFK = C.ConfCityKEYID WHERE MoneyReceived = 1 AND Amount > 0 GROUP BY A.TopicID WITH ROLLUP

dataset = Conference              #entries                   Sum
                       44                               4                            4500
                       45                                5                            4600

I would like to pull the name associated with this TopicID Column

Any help with this would be greatly appreciated.

inluce topic name in the group by:

GROUP BY A.TopicID, A.TopicName

Open in new window

SELECT  ISNULL(CAST(A.TopicID AS VARCHAR(2000)), [Report Total:]) AS [Conference] ,
        ISNULL(A.TopicName, '') [Topic Name] ,
        COUNT(*) AS [Number of Entries] ,
        SUM(A.Amount) AS Sum
FROM    vwApplication A
        INNER JOIN Topic B ON A.Topic = B.Topic
        INNER JOIN ConfCity C ON B.ConfCityFK = C.ConfCityKEYID
WHERE   MoneyReceived = 1
        AND Amount > 0
GROUP BY A.TopicID , A.TopicName
        WITH ROLLUP

I tried that and I got repeats

In Oracle adding brackets in the GROUP BY sequence would remove the unwanted rows - might work in mssql:

SELECT  ISNULL(CAST(A.TopicID AS VARCHAR(2000)), [Report Total:]) AS [Conference] ,
        ISNULL(A.TopicName, '') [Topic Name] ,
        COUNT(*) AS [Number of Entries] ,
        SUM(A.Amount) AS Sum
FROM    vwApplication A
        INNER JOIN Topic B ON A.Topic = B.Topic
        INNER JOIN ConfCity C ON B.ConfCityFK = C.ConfCityKEYID
WHERE   MoneyReceived = 1
        AND Amount > 0
GROUP BY (A.TopicID , A.TopicName) /* small tweak */
        WITH ROLLUP

Actually, I am confused.  

1. You have added A.TopicName so we can only assume that TopicName is already in the VIEW.  Were you intending the TopicName to come from the Topic table instead?  

2. In order to help you, we need to see the contents of the VIEW vwApplication.

3. Please add the appropriate aliases to the columns in the WHERE clause.

I believe you are seeking something like this:
Conference    Topic Name                                  Number of Entries   Sum
11510         Regulation and Function of Small GTPases        1               1015.00
11531         Proteases in Hemostasis & Vascular Biology      1               1450.00
11637         Hematologic Malignancies                        1               1465.00
11807         Membrane Organization by Membrane Scaffolds     1               1300.00
Report Total:                                                 4               5230.00

Open in new window


try this:
SELECT    
          ISNULL(CAST(A.TopicID AS VARCHAR(2000)), [Report Total:]) AS [Conference] 
        , ISNULL(A.TopicName, '')                                   AS [Topic Name] 
        , COUNT(*)                                                  AS [Number of Entries] 
        , SUM(A.Amount)                                             AS Sum
FROM    vwApplication A
        INNER JOIN Topic B ON A.Topic = B.Topic
        INNER JOIN ConfCity C ON B.ConfCityFK = C.ConfCityKEYID

/* you really should have aliases against the following fields */        
WHERE   MoneyReceived = 1 
        AND Amount > 0
        
GROUP BY GROUPING SETS(
        (A.TopicID , A.TopicName)
        )

I tried several variations and can see what this is trying to accomplish, but it will not work.  Thank you for your help with this.

Repeats means that if I am grouping by topic number, I should not see the same topic number in my results more than once.  The columns in the where clause are in the vwApplication.  They arent important.  What is important is that I get the topicname associated with the topic number when using rollup.  I think portletpauls solution will work but the syntax is incorrect.

acperkins,

I added parens and that did not work.

1.  No the topicname is in the vwapplication.  I had the join in the query cause I copied and pasted from another query.  The join can be cut from the query and it will work the same.

2. All of the columns I am referencing are in the view

3.  The where clause does not matter either

That was not me (but see below)

I think portletpauls solution will work but the syntax is incorrect.
Actually the syntax is perfectly correct (I just tested it) at least if you are using SQL Server 2008, as to whether the output is correct, I honestly have no idea as I am not following you at all.  If you would like to supply the schema for all the tables, a SQL Script that populates then with some sample data and tell us what is the expected output, I would be happy to take a second look.

I added parens and that did not work - I then propoed "GROUPING SETS" instead
SELECT    
          ISNULL(CAST(A.TopicID AS VARCHAR(2000)), [Report Total:]) AS [Conference] 
        , ISNULL(A.TopicName, '')                                   AS [Topic Name] 
        , COUNT(*)                                                  AS [Number of Entries] 
        , SUM(A.Amount)                                             AS Sum
FROM    vwApplication A

GROUP BY GROUPING SETS(
        (A.TopicID , A.TopicName)
        ) 

Open in new window

If this isn't working, please identify what version of MSSQL you are using.

If the output isn't meeting some formatting requirement please show us what the query does produce and what you expect the output to be

I tried your proposed solution to use grouping sets, but got a syntax error near SETS.  I am using SQL SERVER 9.0.5069.

Correct SQL Server 2005 does not support that syntax.
