Aggregate Function/Ambiguous Trouble
Nov 18, 2007
I'm a newb and this has been giving me a trouble for a while.
Code Block
SELECT class.classcode, classname, instrFirst, instrLast, csDay, CONVERT(nvarchar(30), csStart, 8), CONVERT(nvarchar(30), csEnd, 8)
FROM class, class_section, instructor
WHERE class.classcode = class_section.classcode
Group By className
Order By classname, csNum;
Msg 8120, Level 16, State 1, Line 1
Column 'class.classCode' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
class and instructor and class_section are their own tables but classcode and instrID are foreign keys on the class_section table. If anyone can explain this as clearly as possible that would be great (the help examples are usually too complicated)

Problem 1:
Suppose I have a table
T( A, B, C, D, E )
I want to retrieve D, E for all rows which have minimum C when we do a group by on A and B. The query would look something like
SELECT D, E FROM T HAVING C = MIN( C ) GROUP BY A, B
Unfortunately, SQL server gives the error that D, E are not in a group by clause. One way is:
SELECT T.D, T.E
FROM
T,
(
SELECT A, B, MIN( C ) AS F FROM T GROUP BY A, B
) AS T1
WHERE
T.A = T1.A AND
T.B = T1.B AND
T.C = T1.F
What I want to know is whether there is a simpler way of doing this or not, kinda like the first illegal query.
Problem 2:
Suppose in the query
SELECT A, B, CASE WHEN C = 'A' THEN 1
WHEN C = 'B' THEN 2 END ORDER
I want to do MIN( ORDER ). The simple way would be
SELECT A, B, MIN( CASE WHEN C = 'A' THEN 1
WHEN C = 'B'' THEN 2 END )
But this gives an error. There is a way:
SELECT T.A, T.B, MIN( T.C ) FROM
(
SELECT A, B, CASE WHEN C = 'A' THEN 1
WHEN C = 'B'' THEN 2 END AS C
) AS T
but I want to know if there is a simpler way to do this (kinda like the first illegal query).

Does anyone know how to make a query and use an aggregate function? This is my current code...any help would be great.
"SELECT tblTopic.Topic_ID, tblTopic.Subject, MAX(tblThread.Message_date) AS MessageDate, tblThread.Message FROM (tblThread INNER JOIN tblTopic ON tblThread.Topic_ID = tblTopic.Topic_ID) WHERE (tblThread.Message_Date LIKE '%' + @fldGenus + '%' GROUP BY tblTopic.Topic_ID, tblTopic.Subject, tblThread.Message">
Also, How can i limit the query to only bringing up 5 records?
I'm trying to get a datagrid to show the 5 most recent forum posts for a particular category.

Hey everyone, I'm looking for a way to insert a count of a set of records into a table and then read that table and produce an XML file from that dataset. The problem that I'm coming across is that when you do this type of query you have to specify one of the values from the table and then get a count for the number of records of that particular range of values.
The table that I am trying to get the data from will look something like this:
ItemID ModuleID Description ......1 2869 blah blah blah2 2869 blah blah blah3 2869 blah blah blah4 2690 bit bit bit5 2690 bit bit bit6 2690 bit bit bit
So I count the 2869's and 2690's and place the ModuleID and the count of the ItemID's in another table.
Then I need to extract the data from the table and put it into an XML file that is readable by the ReadXML method in ASP.NET.
So far I've got the SPROC to do only one record at a time but I would like one that does the whole table rather than one at a time using a parameter.

and this is the error message:

An aggregate may not appear in the set list of an UPDATE statement.
Can someone tell me how to get round this please?
Many thanks

hi there,
I have a query that works on sybase and want to make it also works on SQL Server.
The problem is that in this query I 'm using a subquery in an aggregate function.
It seems that SQL Server unlike Sybase doesn't support the use of subquery in aggregate function.
How can I overcome this problem.
Thanks,

I am working on a view in SQL Server 2005.
I am trying to get a list of the number of sessions each user had by user. I tried doing it this way, but
SELECT userid, MAX
((SELECT COUNT(DISTINCT sessionId) AS SESSIONCOUNT
FROM dbo.Sessions AS OD
HAVING (sessionId = O.sessionId))) AS MAXSESSION
FROM dbo.Sessions AS O
GROUP BY userid
but it throws an error 'Cannot perform an aggregate function on an expression containing an aggregate or subquery.'
Is there an elegant solution for this?

If you use Coalesce with Count will it return all values even when null? Reason I pose this question to you is that I am running the below query and am getting escalated results than what should be returned. 1st stop on the debug train is how does Coalesce handle it....for example Boston should return only 143 but the query retunrs 194 for Boston?
Code:
Select
Count(NumOnsite),
originatingCity,
Coalesce(Convert(varchar(4000),NewspaperNames), Convert(varchar(4000),MagazineNames)) As PaperNames
From readytoshipOffsite
Group By originatingCity, Coalesce(Convert(varchar(4000),NewspaperNames), Convert(varchar(4000),MagazineNames))

Hello,
I want to count how many occurences their is of each date that is returned by my sql query. I am not sure how to add the aggregate function code to my query I know how to just tell it to count all records, but not to tell it to count for each group of dates. For example I want it to count how many times 5/6/08 shows up in the returned results and so on. Here is my query I currently have. Any help would be greatly appreciated! Thanks!
The enc_timestamp is my date field.
Select a.template_id, a.enc_timestamp, a.created_by, b.first_name, b.last_name, b.last_name +', ' + b.first_name as fullname
From template_audit a
Join user_mstr b on a.created_by = b.user_id
GROUP BY a.template_id, a.enc_timestamp, a.created_by,b.first_name, b.last_name
Having a.template_id IN (543,3172,3031,3030,3134,3135,3171,1401,1937,3985,3173,2320,57,849,1775,1400,1747,3695,3957,3750,3954,3027,3241)

Hi guys,
Does anybody know a convenient way to return the product of a column, similar to something like the 'sum' function?
If I have a table of form id-date-value, I'd like to do something like:
select id, date, product(val)
If not, does anyone know of a way one could structure this as a subquery?
If all else fails, I suppose I'll have to resort to a loop or cursor, but I'd rather not.
Any help would be much appreciated.

I am trying to use the following syntax and it is saying I can't use an aggregate function in a subquery. I can't use a GROUP BY in this case because if another field in the project table (such as status) is different, that project will show up twice.So in this case I am using this syntax to show the most recent quote within the project.
SELECT PROJECT.*, QUOTE.QuoteDate, QUOTE.QuoteCode
FROM PROJECT LEFT JOIN QUOTE ON PROJECT.ProjectID = QUOTE.ProjectID
WHERE QUOTE.QuoteDate=(SELECT Max(Q.QuoteDate) FROM QUOTE Q WHERE Q.ProjectID = PROJECT.ProjectID);
My goal here is to show the most recent quote within each project (there can be multiple revisions of a quote within each project). I want to show other fields such as the status of the quote, but if the status is different between quotes, the GROUP BY on that field will cause it to be listed more than once. All I want to show is the most recent quote for each project.

Hi,
I've the following query:
select F_Mode, Issue_Count, Sum(Issue_Count) as IssueSum, milestone from rpt_fact_Paretos
Group By F_Mode having milestone = 'SDS'
Sample Data:
F_Mode Issue_Count milestone
Fail1 5 SDS
Fail2 6 SDS
If the above query is executed, the resultset is:
Fail1 5 5 SDS
Fail2 6 6 SDS
Question: I'm not getting the SUM of Issue_Count. I agree that I'm using F_Mode as Group By and hence the result. But if I use milestone as Group By I won't get all the F_Mode in the result set.
I'm looking for a result like this:
Fail1 5 11 SDS
Fail2 6 11 SDS
How can I achievce this?
Thanks in advance,
SD

I don't know if this is the right forum.
I have a MS ACCESS table like this:
ID - Col1 - Col2
Number - Yes/No - Yes/No
=====================
1 - Yes - No
1 - No - No
2 - No - No
2 - Yes - No
2 - Yes - Yes
I would like to create a view that groups BY ID and combines the boolean columns into 1 value using OR:
ID - Col1 - Col2
=====================
1 - Yes - No
2 - Yes - Yes
Is there an aggregate function for this in T-SQL? If not, how can I solve this?

Hey,
I am running into trouble performing a second join on a column while using aggregate functions over that table.
What I think is happening is that the aggregate values (sum, avg, count) are being multiplied because I am joining on the same table a second time, but I don't know how to fix or avoid this problem.
Here's the query:
---
SELECT
CAST(ro.xing_tc_no AS INT) AS loc_id,
SUM(ro.total_fatal) AS tot_fatal,
SUM(ro.total_serious) AS tot_serious,
SUM(ro.total_minor) AS tot_minor,
COUNT(ro.report_no) AS tot_accidents,
AVG(ro.NO_OCCUPANTS) AS num_occupants
FROM
UserHotspots uh
LEFT JOIN rods_k_crossing AS rkc
ON rkc.location_id = uh.CrossingID
LEFT JOIN rods_occurrence AS ro
ON rkc.tc_location_nbr = ro.xing_tc_no
GROUP BY
ro.xing_tc_no
---
The second join is also performed on rods_k_crossing and that is when the sums, avgs, and counts get multiplied. If I take that second join out the numbers come out fine.
Thanks for any help!

I currently have the following query:
Quote:
select distinct a.memberFirstName, a.memberLastName, c.ChapterName, d.divisionName,
count(f.memberID) as numMembers
FROM Members a
INNER JOIN groupLeaders b
ON a.memberID = b.memberID
Inner JOIN Chapters c
ON c.chapterID = b.chapterID
LEFT JOIN divisions d
ON d.divisionID = c.divisionID
Inner Join groupsOfEight e
ON e.groupLeaderID = b.groupLeaderID
Inner Join groupOfEightMembers f
ON f.groupOfEightID = e.groupOfEightID
Group BY a.memberFirstName, a.memberLastName, c.chapterName, d.divisionName
Order By divisionName, numMembers
This query returns me the names of all of my Group Leaders, their Chapter, Division, and the number of members they have selected to be in their group.
Now, instead of the number of members in each Group I would like to know the total number of Members in each division to appear in the count.
[NOTE: All chapters have a division, linked by a divisionID in the "Chapters" table -- I need to get a count of all the "ChapterMembers" [chaptermembers is a table also] that are in the Division.
Here is the query I started to build before I ran into serious trouble:
Quote:
select a.divisionName, count('c.memberID') as numMembers
From Divisions a
Inner Join Chapters b
On b.divisionID = a.divisionID
Inner Join chapterMembers c
ON c.chapterID = b.chapterID
Left Join Members d
ON d.memberID = c.memberID
LEFT Join groupLeaders e
On e.memberID = d.memberID
Group By a.divisionName
This particular query returns only the DivisonName and the number of Members in the division as expected. However, when I try to select the information for the GroupLeader (first & last name) I am forced to add memberFirstName to the Group By statement which changes my Count...
Have I done an okay job of explaining the problem?
The goal here is to select all of the GroupLeaders first & last name, their chapterName, divisionName, and the total number of members in the division.
Thanks for any advice!

Here is the example:
I have two tables. One has Projects with the total amt of hours worked on the project itself. The other is an Employee_Projects table with individual rows of hrs per employee worked on the above referenced projects.
I need to SUM all the hrs from the Employee_Projects table and GROUP BY project number, then UPDATE the Projects table with the sum of hours where the Project Number from table A matches the Project Number from table B.
Of course, you cant use an aggregate function in an UPDATE clause, so what would be the easiest way to do this??
Any help would be much appreciated.

it gives me my expected output
mtr_5120,0,0,0,0

mtr_5160,0,0,0,0
etc........
now i want to get the min of each column name like so
select @columnname,min(mtr_5120),0,0,0
from temp_prt ------> this works for min(mtr_5120)
mtr_5120,34.5,0,0,0
now I want to generalize so I try to pass in the variable name and I do the following
select @columnname,min(@columnname),0,0,0
from temp_prt
(the columname (@columnname) exists in the table temp_prt)
but now i get an error
Msg 8114, Level 16, State 5, Line 29
Error converting data type varchar to decimal.how can i pass the colunmame into the min and max functions or is that at all ppossible. I also tried the following:
select @columnname,'min(' + @columnname + ')',0,0,0
from temp_prt
but i get the same error

1001 15 5
1002 35 7
1002 10 10
1003 50 30
1004 47 15
We can sum up the quantity with sum function in sql
SELECT SUM(Quantity) FROM OrderTable
How can I get the total quantity without using any aggregate functions?
