Aggregate Issue

Jan 26, 2008

Hi, I am wanting to query the identifier field via the MAX function.

eg.

need to retrieve the BookID of the greatest Book Price

Code:

SELECT BookID,MAX(BookPrice)
FROM Book

this errors, with:

Column 'BookID' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

I realise there are other ways such as referencing back on the same table eg.

Code:

SELECT BookID FROM Book WHERE BookPrice = (SELECT MAX(BookPrice) FROM Book)

but was hoping would be a more direct way, is there a specific direct use of MAX for this purpose or another SQL command?

Analysis :: Calculated Member From Aggregate And Non-aggregate Factors

Sep 22, 2015

I have 2 Dimensions in SSAS (see below end), I want to create a calculated member, named

This_Year_Billable_Objective_Count, with its formula = BillableLastYear*(100+ BillableObjective)/100.

The first factor, BillableLastYear is a number, aggregated (sum) from child units.

The second factor, BillableObjective is a percent number (for example 28 means 28%), it's not aggregate. It's an dependent value for each unit.

How can I calculate This_Year_Billable_Objective_Count for each unit?

\ able 1
SELECT [UnitKey]
,[UnitID]
,[UnitName]
,[Unit2Name]
,[Unit3Name]
,[Unit4Name]

[Code] .....

Using Aggregate

Mar 24, 2008

I have a table that has 4 colums (id,projectno,date,price)
i want to make a select that returns the sum per project no
i used this query
select projectno,sum(pice) as sum
from supplier
group by projectno

but i want to include additional columns like id and date for the result
but its giving this message:
Column 'supplier.id' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

is there a better way to do so without joining the main table with the upper select query?
Best Regards

Aggregate On An Aggregate

Sep 25, 2007

I need to get the sum of a field that already has an aggregate function (MAX) performed on it. I am using the following query

Code Snippet
SELECT "tI"."ItemID", MAX("vSS"."ShortDesc") "Short Description",
MAX("tPCT"."FreezeQty") "Freeze Qty", SUM("vSS"."QtyOnHand") "Current Qty",
"tPCT"."BatchKey"
FROM ("vSS" "vSS"
INNER JOIN "tI" "tI"
ON "vSS"."ItemKey"="tI"."ItemKey")
LEFT OUTER JOIN "tPCT" "tPCT"
ON "vSS"."ItemKey"="tPCT"."ItemKey"
WHERE "vSS"."ItemID" = '3002954'
GROUP BY "tI"."ItemID", "tPCT"."BatchKey"

It yields the following results

ItemID
Short Description
Freeze Qty
Current Qty
BatchKey

3002954
SET, WRENCH HEX METRIC
-33
129
42221

3002954
SET, WRENCH HEX METRIC
51
129
42244

3002954
SET, WRENCH HEX METRIC
-31
129
42250

I need to SUM the maximum freeze quantity values per item ID. Therefore for this record, I need the following results:

3002954 SET, WRENCH HEX METRIC -13 129

Can this be done via a subquery? Any assistnance would be greatly appreciated?

Thanks,
DLee

Help With Aggregate Query - Can't Get It Right!!

Jun 17, 2007

Hi,
I have we have a client who gives their invoices in a flat file format, we import it into a SQL Server table.
Nothing is normalized – everything is repeated in every record. The fields are:
customerNumberInvoice_numberPO_numberQtyDescriptionLine_numberLine_totalFreightTaxInvoice_date
So an if an order has 10 line items, the header information (invoice number, PO number, ivoice date) are repeated on each of the lines
I am writing a query to show the following
Order number, Invoice total, Date
select invoice_no, sum(line_total + freight + tax) as invoiceTotal, customerNumber, Invoice_date from invoices group by invoice_no, Invoice, customerNumber
This works great - for each invoice I get the invoice number, InvoiceTotal, and Date
Then I was asked to add the PO Number – this is where I can’t get it right.
When I added “PO_number�? to the query, I got two lines for each invoice
select invoice_no, sum(line_total + freight + tax) as invoiceTotal, customerNumber, Invoice, PO_number from invoices group by invoice_no, Invoice, Sold_To_Cust_No, PO_number
Please help - I need to end up with: invoice_no, invoiceTotal, customerNumber, Invoice_date and PO_number (sequence does not matter)
Thanks

Aggregate Functions

May 14, 2008

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.

Aggregate Sum Query, Need Help

I have two tables tb1 with item and qtyOnHand and a second table tb2 with item and qtyOrdered I am trying without success to make this happen;select sum (onHand-Ordered) from (select sum (qtyOnHand) from tb1 where item = RD35 group by item) as onHand, (select sum (qtyOrdered) from tb2 where item = RD35 group by item) as OrderedI kind of gathered it would work based on this http://weblogs.asp.net/jgalloway/archive/2004/05/19/135358.aspxI have also tried this;select tb1.item from (select sum (qtyOnHand) from tb1 where item = RD35 group by item) as onHand, (select sum (qtyOrdered) from tb2 where item = RD35 group by item) as Ordered, sum (onHand-Ordered) as available from tb1 where tb1.item = RD35Any ides, there are multiple rows of each item in each table tb1 is inventory with several different locations and tb2 is an orders table.

Stream Aggregate

Jul 24, 2001

What I'm trying to solve:
I have an application that generates SQL queries, and sometimes uses
DISTINCT where the result set has no dupe rows. In terms of database
resources, I'm trying to figure out if it's worth it to change to app to be
smart enough to not use DISTINCT where it won't serve any purpose, or
whether to let it do the DISTINCT and save added complexity to the query
building application. I.e. what is the cost of DISTINCT where there are no
dupe rows?

What I want to know:
Can someone explain how the stream aggregate operator actually goes about
doing its work?

Does this always create a temp table for sorting and discarding duplicates
(for DISTICNT)? If the answer is "no or sometimes", how does it do so in
the case where a temp table is not involved? I noticed the the estimated
I/O for this operator was zero for some queries I wrote agains pubs. Does
this mean that the optimizer believes the temp table needed will fit
in-memory and creates it in-memory? Or does the estimated I/O figure not
included disk writes for work tables?

tia for any info
Bill

Aggregate Navigator

Jan 20, 2000

Hello,

I was told that on Oracle there's something called an Aggregate Navigator which should be capable of changing the table you're addressing in a query to another table (with aggregate data) and in this way optimize performance in a data warehousing environment.

Is there anything similar in MS SQL Server?

Use Aggregate Values

Jun 6, 2003

Hi all,

I have a table with the following fields:

carrier,calc_date,ind_id,rcf

I need to run a query to get the following result(by carrier and for each calc_date, calculate the percentage of all individuals who have rcf greater than 0.73):

carrier,calc_date,count of ind with rcf > 0.73, count of all individual, percentage of individuals with rcf's greater than 0.73.

does anyone have an idea of how to achieve that result?

Thanx

Aggregate Problem

MS Access provides FIRST and LAST aggregates to select the first and last values from a group.

Qualifying What Goes In An Aggregate

Jun 15, 2006

Greetings!

I'm hoping for a little insight for a novice.

Here's what I have:

1 table that looks like this...

Code:

rep_id answer
1 2
1 1
2 1
3 0
3 1
3 1
4 2

What I want is a recordset returned as ... (columns that tally the 1s and 2s respectively with the rep's id#)

Code:

rep_id total1 total2
1 1 1
2 1 0
3 2 0
4 0 1

What I can do so far is get individual recordsets returned for either total1 or total2 but not together.

Here's what I'm using for these...

Code:

SELECT rep_id, COUNT(answer) as total1
FROM myTable
WHERE answer = '1'
GROUP BY rep_id

and

Code:

SELECT rep_id, COUNT(answer) as total2
FROM myTable
WHERE answer = '2'
GROUP BY rep_id

So how do I form a SQL statement that will combine the 2 columns I have created into 1 joined by the rep_id?

To make it a little stickier there may be some nulls in the existing answers but hopefully that is not going to bung me up.

Any help will be thankfully received!!!

The Aggregate For Several Fields In Same Row?

Jun 11, 2007

I need to find an aggregate for several fields in a row
e.g. Max(date1, date2, ..., dateN)

I can pass this to a delimited string,
pass the string to an UDF that returns a table
and run Max(tablefield) on that UDF

Unfortunately I can only get this working for 1 delimited string at a time

Ideally I would want to include the function in a SELECT statement, e.g. something like

SELECT t1.a, dbo.MaxOfFieldValues(t1.d1+','+t1.d2+...+','+t2.dN )
FROM t1

I got it working with the following two udfs, but I am sure visitors here have solved this a bit smarter:

ALTER Function [dbo].[MaxOfFieldValues]
(
@ListOfValues varchar(8000)
, @delimiter varchar(10) = ','
)
RETURNS VARCHAR(8000)
AS
BEGIN
--Need to get the maximum changedate first
--pass the fields as one value (a delimited string)
--and calc the max
declare @result varchar(8000)
declare @remainder varchar(8000)
set @remainder = @ListOfValues
declare @NoOfItems int --items = delimiters +1
SET @NoOfItems = (len(@ListOfValues) - Len(Replace(@ListOfValues,@delimiter,''))/Len(@ListOfValues))+1
declare @counter int
set @counter =1
set @result = dbo.TakePart(@remainder,@delimiter,@counter)
WHILE @counter <= @NoOfItems
BEGIN
set @counter = @counter + 1
IF @result < dbo.TakePart(@remainder,@delimiter,@counter)
BEGIN
SET @result = dbo.TakePart(@remainder,@delimiter,@counter)
END
END
RETURN (@result)
END

ALTER FUNCTION [dbo].[TakePart]
(
@param varchar(8000)
, @delimiter varchar(10)
, @NumPart int
)
RETURNS varchar(8000)
AS
BEGIN
--Note: maybe smarter to whack the delimiter to the end of the string to avoid the IF statement
declare @result varchar(8000)
declare @remainder varchar(8000)
declare @counter int
set @result = ''
set @remainder = @param
set @counter = 1
WHILE @counter < @Numpart
BEGIN
SET @remainder = SUBSTRING(@remainder,CHARINDEX(@delimiter,@remaind er,1)+Len(@delimiter),8000)
SET @counter = @counter +1
END

IF @counter > (len(@param) - Len(Replace(@param,@delimiter,''))/Len(@delimiter))
BEGIN
SET @result = @remainder
END
ELSE
BEGIN
SET @result = LEFT(@remainder,CHARINDEX(@delimiter,@remainder,1) -1)
END

RETURN @result
END

Regarding Aggregate Conditions ..

Nov 29, 2007

Hai frns small help needed.

I have a table called sample and i have the following requirement. i.e i need sum(credit) group by ssn no.

One special condition is as follows:

For each distinct ssn if "flag" has the same CX value,then out of all the records with the same CX value, the highest "credit" value is added to the sum for that "ssn" and the rest are ignored.
If while adding "credit" to the sum and if "credit" value is equal to zero then "sum" value is used for summing else "credit" value is used.
Can any one help me out in trying this logic. I have tried but i could'nt able embed the conditions inbetween the Sql statetment.

Here is the query is used

select * from sample

idssncreditflagsem
11010C90
21014C93
31014.5C92
41013.5C11
51024.2C33
61030C12

select ssn,flag,sum(case credit when 0 then sem else credit end) as sum from sam2
group by ssn,flag

ssn flag sum_val
101C13.5
103C12.0
102C34.2
101C98.5

The above output is wrong one.

Expected output

101 4.5+3.5=8.0
102 4.2
103 2.0

Any help would be appreciated

Aggregate Comparisons??

What I want to do is report on users who have logged on to the software using someone else's workstation (i.e. logged on to more than one workstation).

Here's some sample stuff to play with

DECLARE @logins table (
loginName char(20)

)

--Insert test data. Please note that loginName and ntUsername are rarely the same

SELECT 'Bob', 'Bob', '20070102' UNION
SELECT 'Bob', 'Amy', '20070103' UNION --Bob has logged on using 2 different NT accounts
SELECT 'Cal', 'Cal', '20070102' UNION
SELECT 'Cal', 'Amy', '20070102' UNION --So has cal
SELECT 'Dom', 'Dom', '20070102' UNION
SELECT 'Dom', 'Dom', '20070102'

Any ideas? I just can't think of the logic needed to get what I want.

Any extra info needed - just ask!

Aggregate Functions..

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?

First, It should get all items from @ItemHistory where WHERE DateSold >= '1/10/2007' AND DateSold < '1/11/2007'
and then checks if corresponding items are found in @ItemStock,
and then returns all the ItemID where sum(@ItemStock.Quantity) < sum(@ItemHistory.Quantity)

Thank You.

Here is the DDL and DML

DECLARE @ItemHistory TABLE (
ItemID INT,
Quantity INT,
DateSold DATETIME )
INSERT INTO @ItemHistory
SELECT 12, 18, '2007-01-10' UNION ALL
SELECT 12, 18, '2007-01-10' UNION ALL
SELECT 26, 12, '2007-01-10' UNION ALL
SELECT 28, 06, '2007-01-10' UNION ALL
SELECT 29, 06, '2007-01-10' UNION ALL
SELECT 30, 06, '2007-01-10' UNION ALL
SELECT 31, 06, '2007-01-10' UNION ALL

SELECT 32, 12, '2007-01-10' UNION ALL
SELECT 33, 01, '2007-01-10' UNION ALL
SELECT 33, 06, '2007-01-10' UNION ALL
SELECT 36, 01, '2007-01-10' UNION ALL
