Aggregate (SUM) A Column And Then Use The Result?
May 7, 2007
Hi,
I am importing some data from Excel. I have to SUM one of the columns, and then use the result of the sum to calculate the percentages of each row. How can I use the Aggregate to give me a total of a column, so that i can use the total in another task and use formulas to calculate the percentages? i have tried to use multicast and join, but I get an extra row with the sum, which is not what I want; I want to use the sum for all the data.
Thanks

Ok, for a bunch of cleanup that i am doing with one of my Portal Modules, i need to do some pretty wikid conversions from multi-view/stored procedure calls and put them in less spid calls.
currently, we have a web graph that is hitting the sql server some 60+ times with data queries, and lets just say, thats not good. so far i have every bit of data that i need in a pretty complex sql call, now there is only one thing left to do.
Problem:
i need to call an aggregate count on the results of another aggregate function (sum) with a group by.
*ex: select count(select sum(Sales) from ActSales Group by SalesDate) from ActSales
This is seriously hurting me, because from everything i have tried, i keep getting an error at the second select in that statement. is there anotherway without using views or stored procedures to do this? i want to imbed this into my mega sql statement so i am only hitting the server up with one spid.
thanks,

The actual schema I'm working against is proprietary and also adds more complication to the problem I'm trying to solve. So to solve this problem, I created a mock schema that is hopefully representative. See below for the mock schema, test data, my initial attempts at the query and the expected results.
-- greatly simplified schema that makes as much sense as the real schema
CREATE TABLE main (keyvalue INT NOT NULL PRIMARY KEY, otherdata VARCHAR(10));
CREATE TABLE dates (datekeyvalue INT NOT NULL, keyvalue INT NOT NULL, datevalue DATE NULL, PRIMARY KEY(datekeyvalue, keyvalue));
CREATE TABLE payments (datekeyvalue INT NOT NULL, keyvalue INT NOT NULL, paymentvalue INT NULL, PRIMARY KEY(datekeyvalue, keyvalue));
[Code] ....
Desired results:
SELECT 1 AS keyvalue, 'first row' AS otherdata, '2015-09-25' AS nextdate, 30 AS next_payment
UNION ALL
SELECT 2, 'second row', '2015-10-11', 150
UNION ALL
SELECT 3, 'third row', NULL, NULL
I know I'm doing something wrong in the last query and I believe another sub-query is needed?
Let me answer a few questions in advance:
Q: This schema looks horrible!
A: You don't know the half of it. I cleaned it up considerably for this question.
Q: Why is this schema designed like this?
A: Because it's a 3rd-party mainframe file dump being passed off as a relational database. And, no, I can't change it.
Q: I hope this isn't a frequently-run query against a large, high-activity database in which performance is mission-critical.
A: Yes, it is, and I left out the part where both the date and the amount are actually characters and have to pass through TRY_CONVERT (because I know how to do that part).

I've put a SelectCommand with an aggregate function calculation and AS into a SqlDataSource and was able to display the result of the calculation in an asp:BoundField in a GridView; there was an expression after the AS (not sure what to call it) and that expression apparently took the calculation to the GridView (so far so good).
If I write the same SELECT statement in a C# code behind file, is there a way to take the aggregate function calculation and put it into a double variable? Possibly, is the expression after an AS something
that I can manipulate into a double variable? My end goal is to insert the result of the calculation into a database.
What I have so far with the SelectCommand, the SqlDataSource and the GridView is shown below in case this helps:
<asp:GridView class="gridview" ID="GridView2" runat="server" AutoGenerateColumns="False" DataSourceID="lbsgalDataSource">
<Columns>
<asp:BoundField DataField="Formulation" HeaderText="Formulation" SortExpression="Formulation" />
<asp:BoundField DataField="lbs" HeaderText="lbs" SortExpression="lbs" />
<asp:BoundField DataField="gal" HeaderText="gallons" SortExpression="gal" />
<asp:BoundField DataField="density" HeaderText="density" SortExpression="density" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="lbsgalDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT
a.Formulation,
SUM (a.lbs) AS lbs,
SUM ((a.lbs)/(b.density)) AS gal,
( ( SUM (a.lbs) ) / ( SUM ((a.lbs)/(b.density)) ) ) AS density
FROM Formulations a INNER JOIN Materials b
ON a.Material=b.Material WHERE Formulation=@Formulation GROUP BY Formulation">
<selectparameters>
<asp:controlparameter controlid="DropDownList1" name="Formulation" propertyname="SelectedValue" type="String" />
</selectparameters>
</asp:SqlDataSource>

How do I aggregate a column by concatenation?
/*
SQL Server 2000 datbase
I have 3 tables.
A "client" table.
A "call history" table.
And a "call detail" table.
The "client" table contains data about individual clients.
The "call history" table contains data about calls to or from the clients in the "client" table. (This is a one-to-many relationship of client-to-history interactions.)
The "call detail" table contains detail data about a particular "call history" entry. (This is also a one-to-many relationship of history-to-detail entries.)
*/
Code:
DECLARE @Client TABLE (ClientID INT PRIMARY KEY, ClientName VARCHAR(100))
INSERT INTO @Client
SELECT 1 [ClientID], 'Client A' [ClientName]
UNION ALL SELECT 2, 'Client B'
UNION ALL SELECT 3, 'Client C'
UNION ALL SELECT 4, 'Client D'
SELECT c.ClientID, c.ClientName

I am trying to get a culmulative Bitwise OR operation on a column by query - rather than using a CLR function.
The problem is shown below:
CREATE TABLE #Operations (
PK INT NOT NULL IDENTITY(1,1),
UserName VARCHAR(50) NOT NULL,
UserProcess VARCHAR(50) NOT NULL,
ServerOperation VARCHAR(50) NOT NULL,
Permission INT NOT NULL );
[Code] ....
So Far I've tried SUM - wrong results, and STUFF - which doesn't seem appropriate for bitwise operation - neither give useful results.
-- SUM Operation - fails
SELECT DISTINCT
UserName,
ServerOperation,
SUM(Permission) AS Permission
FROM #Operations
[Code] ....
It may be possible to materialise the permissions each time one is changed (e.g. by to use a cursor ), however I would prefer a query or function or combination to generate the result.

Loc Value Time
A 3 1AM
A 8 2AM

When we collapse the Loc group I want to show the Max vlaue and the time it
occurred.
A 8 2AM

What is the expression for the Time column of the table to ensure
the time of the maximum value is shown?

I am no expert in sql, but I keep stubbling on this problem:I have a table t1 with 2 columns (a,b)I have a table t2 with 2 columns (c,d)I need to delete all records from t1 which have the same value (a,b)than the value of (c,d) in all records in the t2 table.I oracle, this is simple:delete from t1where (a,b) in (select c,d from t2)because Oracle has support for this syntax. Dont remember how they callit. But this is not support in sql server. So I have to resort to:delete from t1where a + '+' + b in ( select c + '+' + d from t2)Of course, a,b,c,d must be varchar for this to work. Basically I fake aunique key for the records. Is there a better way to do this?Thanks

create a sequential aggregate of a column using sum in tsql.
I want a column that will sum up all hours work by transaction date.
for example
Monday my hours work will be 8 and therefore my total transaction hours will be 8.
Tuesday my hours work will be 8 but I want the total hours of my total transaction hours to 16.
Wed my total hours work will be 5 and I want the total hours of my total transaction hours to 21. etc.
Select myname, weekday, hours worked, Totalhours_ToDate =Sum(hours worked) from table

How can do this. Because my stored function contains same clause except colums name.So I want to use column name as a parameter but how can send column name and use it like Sum(parameter) function .
my procedure like this:
ALTER PROCEDURE [dbo].[ORNEK10]
@YIL VARCHAR(4),
@TEKLIF_TURU VARCHAR(255)
AS

DECLARE @N2 FLOAT

SET @N2 = ( SELECT DEGERI FROM PARAMETRE WHERE PARAMETRE_ADI='N2')
SET NOCOUNT ON;
--I want to avoid using if statements for Sum() function
IF(@TEKLIF_TURU='BASKAN_TEKLIF')
SELECT TOP (100) PERCENT KOD1, KOD2, KOD3, KOD4, dbo.ORNEK10AD(KOD1, KOD2, KOD3, KOD4) AS ACIKLAMA,

I have a simple query like:
select max(PTR_DATE)
from MPR_portfolio_transactions
group by PTR_SYMBOL
and this is working fine, but if I add an extra column with another field like:
select max(PTR_DATE) , PTR_SHAREBALANCE
from MPR_portfolio_transactions
group by PTR_SYMBOL
Then I get an error message like:
Column 'MPR_portfolio_transactions.PTR_SHAREBALANCE' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
How can I get round to this?

I have a specific variation on the standard 'Column Invalid' question: I have this query that works fine:
SELECT vd.Question ,
csq.Q# ,
csq.Q_Sort ,
csq.Q_SubSort ,
AVG(CAST(vd.Response AS FLOAT)) AS AvgC ,
vd.RType
[Code] ....
When I add this second average column like this:
SELECT vd.Question ,
csq.Q# ,
csq.Q_Sort ,
csq.Q_SubSort ,
AVG(CAST(vd.Response AS FLOAT)) AS AvgC ,
[Code] ....
I get the error: Column 'dbo.vwData.Response' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
Clearly things are in the right place before the change, so I can only assume that the OVER clause is my problem. Is this just not possible?

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?

I have a brain teaser for you all.
The end result: I need one of the columns in my result set (col2) to have a preceeding apostrophe (i.e., '001234 ).
The problem: I am building my query as a string and then using the EXEC() function to execute it. For example:
SET @strSQL = 'SELECT col1, col2 FROM mytable'
EXEC(@strSQL)
Just to tame any answers that might not be directed to the specific question, the query Must be built as a string and then executed.
I have been unable to obtain the solution and I am wondering if it is even possible?

Simple example would look like that in MS SQL
SELECT 'a' AS (SELECT language_name FROM language WHERE language_id = 1)
So that the display is
English
a
as we assume that
SELECT language_name FROM language WHERE language_id = 1
returns only English
I have tried to that with a variable but it does not work
declare @that as varchar(15);
set @that = (select language_name_u from language where language_id = 1);
select 'a' as @that
LOL
I just tried another way as i was going to post
declare @that as varchar(15);
set @that = (select language_name_u from language where language_id = 1);
select 'a' as "@that"
and it worked!
Posting anyway so people might answer with a better solution with no variable
Thanks a lot

Using @MyValue = 23 should make the Sum(Price) column name 'Price_23'. It's not working. What am I doing wrong?

Is there a way to ignore a column/variable when the whole result set for the applied filter (where) is null?
Not all clients have data for every variable, i.e. some variables are client specific. There are too many variables and clients to amend the select query every time so I just want to ignore a col if its null.
I hope that makes sense (my inability to describe it might explain my inability to find anything related to it!)
The next step would be to run all clients' data in one go using, I believe, a cursor, but one step at a time!

I have a query where one or more of the columns returned is a resultfrom a subquery. These columns get their own alias. I want to filterout the rows containing NULL from the subqueries but it just won'twork. When running columnAlias IS NOT NULL i just get the error"Invalid column name 'columnAlias'.This is the query:SELECT k.UserId, k.Lastname, k.Firstname,(SELECT kscr.answer FROM Results kscr WHERE kscr.UserID =k.UserID) AS myColumnAliasFROM Users kWHERE myColumnAlias IS NOT NULL)When running without the WHERE clause, I get the following results:UserId Lastname Firstname myColumnAlias113 Norman Ola jepps820 Karlsen Kjell830 Pens Jens juubidooWhat I want is to get rid of UserId=820. What am I doing wrong?
