How to write Aggregate functions for tables and lists as If I can write them many problems in my reports will be solved. I tried writng it in the filters but I got an error saying Aggregate functions are not allowed for tables and lists. Can any one help me in this regard?????
View 4 RepliesHi, need help in this statement here. I have three tables here, i.e. Sales, SalesItem, & SalesPmt. I want to display a grid that shows the Total Bill and Total Payment amounts.
My try is like this: SELECT SalesNo, SUM(Price*Qty) AS TotalBill, SUM(Payment) AS TotalPayment FROM ... GROUP BY....
No syntax error or whatever found, but the result of the total amounts is incorrect.
Say the data of the respective table below:
SalesItem
No
Qty
Price
1
1
5.00
2
2
12.00
3
4
3.50
SalesPayment
No
Amount
1
10.00
2
5.00
But the result I get from the above query is:
TotalBill
TotalPayment
86.00
45.00
Total Bill should be 43.00 and Total Payment should be 15.00.
Apparently the problem is due to the fact that I and querying on multiple tables. The correct total payment amount was multiplied by the number of rows of sales items (15.00 x 3), while the correct total bill amount was multiplied by the number of rows of sale payments (43.00 x 2).
So, what is the better way of writing this query?
Hello,
I`ve created a table in a list that is grouped by years. Result is a Report, that consists of several years (List grouped by years, each containing the table with the data of the year).
Now I want to aggregate some numbers of the table on each page (year) of the list.
The sum()-function - doesn't matter which scpoe I use - always aggregates only the values of the actual list (Year), not considering the years before.
Can anyone help?
Thanks a lot -

I have a table that is used for employee evaluations. There are six questions that are scored either 1, 2, 3, 4, or 5. I want to tally the responses on a page, but I wonder if I can do it without 35 separate calls to the database (I also want to get the average response for each question). I know I can do "SELECT COUNT(intWorkQuality) AS Qual1 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '1' " and then "SELECT COUNT(intWorkQuality) AS Qual2 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '2' " and so on. But can I somehow do the aggregating at the page level, and just refer back to a datasource that uses a generic statement like "SELECT intWorkQuality, intDepend, intAnalyze, intWrite, intOral, intCompatibility FROM dbo.Summer_Project_Req"? If I can, I am not sure what type of control would be best to use or what syntax to use to write the code-behind. I would like the results to be displayed in a grid format. Thanks in advance for your help.

Hi..
I'm doing a jsp with database using sql.. I'm trying to get the max of score group by name from this table:
Table record
id_no. . . .name. . . . .score
. . 1 . . . . .Philip . . . . .10
. . 2 . . . . . Jane . . . . .12
. . 3 . . . . . John . . . . .15
. . 4 . . . . . Anna . . . . .11
. . 5 . . . . . Jane . . . . .16
I use the code:
query = "select name,max(score) from record group by name";
resultset = stmt.executeQuery (query);
However, there is an error. It says, SQL Exception: Column not found
I've checked several tutorial sites and the codes there are the same command that I use. I've also tried using other aggregate functions like the sum, still the same error comes out..
Why is that so? What should I do?
Thanks a lot..
I'm trying to migrate an app. from Access to SQL Server, and find that Transact-SQL does not support LAST/FIRST functions. Is there any alternative to these?
Below is the Access SQL statement:
SELECT Last(tblZoneNameString.Val) AS strZoneName, tblZoneNameString.TagIndex
FROM tblZoneNameString
GROUP BY tblZoneNameString.TagIndex
HAVING (((tblZoneNameString.TagIndex)>0));
I'm using the data environment of VB 6.0 to create data reports.
In Oracle you can use a nested aggregate function in a select query like MAX(SUM(Field)). Can I do this in SQL? If so, how?
thanx
Hi everyone,
I have a database with the following tables:
- programmer
- software
- studies(name, splace, cost, course)
I would like to find out which school has the max. nr. of students, but my query - SELECT splace FROM studies HAVING count(name) = (SELECT max(count(name)) FROM studies) - doesn't works, becouse MSSQL doesn't supports nested aggregat functions.
What should I do? Please help me, thanks in advance.
Something a little different: C# on SQLTeam!
It's basically just cobbled together using the aggregate function and TVF in the StringUtilities sample as a starting point.

I have a select statement like this:
"SELECT AVG(Price) FROM prices GROUP BY Category"
Which of course returns a list of average prices.
I want to get a sum of that list, something that would work like this:
"SELECT SUM(SELECT AVG(Price) FROM prices GROUP BY Category)"
That code doesn't work, but that's what I want it to do and I'm not sure how to do it.
Thanks!
Hi.Just as we have AVG(COLUMN_NAME) and MAX(COLUMN_NAME) how can I writemy own variation of a such a function. If I can appreciate how to dothis,then I hopefully I can write a MEDIAN(COLUMN_NAME) type function or amore general function like a 10% percentile function with syntax suchasPERCENTILE(COLUMN_NAME,25).Regards JC......

Hi there,
I'm probably just being thick but is there a way to use conditional statements within aggregate functions? I'm trying to do something along the lines of the following -
Code:
SELECT SUM(
CASE
WHEN Currency='GBP' THEN TotalAmountCharged
ELSE TotalAmountCharged/1.45
) as total
from bookshop_orders
where year(OrderDate) = 2004 and month(OrderDate) = 9
TIA

Howdy,I need to write an update query with multiple aggregate functions.Here is an example:UPDATE tSETt.a = ( select avg(f.q) from dbo.foo f where f.p = t.y ),t.b = ( select sum(f.q) from dbo.foo f where f.p = t.y )FROM dbo.test tBasically I need to get some aggregate statistics about the rows offoo and store them in rows of t. The above statement works fine...butnote how the two subSelect's have the exact same WHERE clause. Thisscreams at me to combine them...but how? I would like to havesomething like this in my query:SELECT avg(f.q), sum(f.q) FROM dbo.foo f WHERE f.p = 2...and somehow store the results in t.a and t.b. Is there any way todo this?Thanks before hand!
View 6 Replies View RelatedHi Guys,
I am having trouble with a particular query that is beyond my scope of understanding.
Basically I need to pull sales records based on the following criteria:
I have CustomerID, InvoiceNumber, ContractEndDate, MobileNumber, etc..
Customers recontract their mobile phone plans through us, and we have a new sales record for each time they recontract.
For example, CustomerNumber 123 has recontracted 3 times..
once on 2006-01-01, then on 2007-02-12, and finally on 2008-02-15..
So they have a 12 month contract each time.. then come in to recontract it.
So.. a customer has a single Customer Detail record, but may have many sales records attached. And a customer may have several sales for the SAME mobile phone number.
Currently to pull ALL sales records for all customers, my query is this:
Code:
SELECT xxx.CustomerID AS xxx_CustomerID,
xxx.Invoice AS xxx_Invoice,
yyy.PhoneType AS yyy_PhoneType,
yyy.PlanType AS yyy_PlanType,
yyy.ContractEnds AS yyy_ContractEnds,
yyy.MOB AS yyy_MobileNumber
FROM dbo.SaleControl xxx INNER JOIN dbo.SaleDetails yyy ON xxx.Invoice = yyy.Invoice
WHERE yyy.ContractEnds IS NOT NULL
AND xxx.CustomerID IS NOT NULL
We want to get a list of customers that we can call to recontract, based on the ContractEnd field.
However, we want UNIQUE mobile phone numbers, with the LATEST ContrtactEnd date.
So, Customer 123 has 6 sales, for 2 unique Mobile numbers, the sql may be like:
Code:
SELECT MAX(yyy.ContractEnds) AS LatestCED, yyy.MOB
FROM dbo.SaleControl xxx INNER JOIN dbo.SaleDetails yyy ON xxx.Invoice = yyy.Invoice
WHERE xxx.CustomerID='123'
GROUP BY yyy.MOB
Now, this works fine, and of course if i remove the WHERE clause, it collects all unique mobiles, with latest ContractEnd date for each, for all customers. (Customer 123 displays 2 mobile numbers, each with the LATEST ContractEnd date)
BUT i need this information ALONG WITH the other fields (xxx.CustomerID, xxx.Invoice, yyy.PhoneType, yyy.PlanType) and i have tried a few ways of doing it, but can't get my head around it..
Keep getting errors about Aggregate functions and Group By clause, and i understand why i am getting them, just cant think of any alternative query.
Can anyone please help me!
Thanks guys,
Mick

Hi,
Assume there is no sale with over 2000 units, the first query returns no row while the latter returns 1 row with a null value. I am not questioning the result, I would like to understand conceptually what semantic difference between the Sql99 analytic function and regular aggregate function makes the result different in this case.
select sum(Quantity) over() from orderdetails where Quantity > 2000
select sum(Quantity) from orderdetails where Quantity > 2000
thanks in advance,

I have report showing sales by Vendor. I need to list all the vendors with Monthly Total>5000 and combine the rest as "OTHER VENDORS"
Vendor is a Group in my report, so I tried to put an expression as a Group on:
=IIF(Sum(Fields!Mth_1_Sales.Value)>5000,Fields!Vendor_No.Value,"OTHER VENDORS")
I've got an error: "aggregate functions cannot be used in group expressions"
How do I get Vendors with Sales < 5000 into "OTHER VENDORS" ?

Are groups within a list or table forced to be kept on the same page (if possible)? If so, is there any way around this?
My problem is a report with a list with 3 tables inside the list. All tables show details associated with the grouped individual. The size of one list item can be slightly smaller than half a page or over. When the report can not fit two list items on one page, it starts a new page and leaves unwanted white space.
I have tried:
adding a rectangle
adjusting width, margins, etc.
not using lists, only tables nested within tables
to check for page breaks, I adjusted the page size to 8.5 X 20. Same thing occurs, as many lists as possible on one page without splitting between pages.Thanks for any guidance.

I have three tables:
1) Contract - columns ContractNo and ContractName
2) SalesTransactions - multiple rows for each contract - relevant columns: ContractNo, InvoiceDate, Value
3) CostOfSaleTransactions - multiple rows for each contract - relevant columns: ContractNo, TransactionDate, Cost
How do I write a SELECT statement to produce rows containing:
ContractNo
ContractName
Sum of Value for ContractNo between @FromDate and @ToDate
Sum of Cost for ContractNo between @FromDate and @ToDate
Not all Contracts have either Sales or CostOfSales Transactions in the relevant date range and so one or both totals can be zero.
I've written something like:
SELECT CT.ContractNo, CT.ContractName, sum(CT.Value) as TotalValue, Sum(CS.Cost) as TotalCost
FROM Contract CT
INNER JOIN SalesTransactions ST ON CT.ContractNo=ST.ContractNo
INNER JOIN CostOfSaleTransactions CS ON CT.ContractNo=CS.ContractNo
WHERE (ST.InvoiceDate BETWEEN @FromDate AND @ToDate) AND (CS.TransactionDate BETWEEN @FromDate AND @ToDate)
GROUP BY CT.ContractNo, CT.ContractName
The TotalValue and TotalCost figures I get are much higher than expected. I presume this is something to do with the JOINs or WHERE clause. Please can you advise how I get the correct values?
I have created the following view:
Create view vwOrderItemTotal2
AS
SELECT ItemName, fkMenuItemID, Sum(Quantity) as [SumOfMenuITems] FROM OrderItems GROUP BY fkMenuItemId, ItemName
When I present my data in a GridView, it works fine. For example, several orders for milk are returned as a summary quantity of 26 gallons in a single row of the GridView like this:
26 Milk
Now I need to filter my data by OrderDate and Zipcode. I created this new view:
Create view vwOrderItemTotal5
AS
SELECT Orders.Zipcode, Orders.OrderDate, OrderItems.ItemName, OrderItems.fkMenuItemID, Sum(Quantity) as [SumOfMenuITems]
FROM Orders INNER JOIN OrderItems
ON Orders.OrderID = OrderItems.fkOrderID
GROUP BY fkMenuItemId, ItemName, Zipcode, OrderDate
When I present my data in a Gridview using the new view I get a GridView with multiple rows for milk where each order has its own row like this:
1 Milk
5 Milk
6 Milk
6 Milk
3 Milk
1 Milk
4 Milk
But I want the data presentation in one row for each ItemName (e.g. Milk) as with my first view. Can I adjust my new view to achieve this, or should I stick with my first view (vwOrderItemTotal2) and adjust the Select Command in my SqlDataSource (hasn’t worked yet).
I think that what I want is for the returned data to be grouped by fkMenuItemId only, but the sql server admin won’t let me create a view without including the other fields in the Group By clause. Thanks for any help provided in solving this.
