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.
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, Tom Anderson Software Engineer Custom Business Solutions
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">
I have a column that has an expression with a runningvalue in it, a "Carrying Cost" for each month. I need to create another column that aggregates the monthly Cost. I can't to do a Runningvalue on the Runingvalue. I can't even do a Sum on the Runningvalue.
Hi,Suppose I have a table containing monthly sales figures from my shopbranches:Branch Month Sales-----------------------London Jan 5000London Feb 4500London Mar 5200Cardiff Jan 2900Cardiff Feb 4100Cardiff Mar 3500The question I am trying to ask is this: in which month did each branchachieve its highest sales? So I want a result set something like this:Branch Month----------------London MarCardiff FebI can do a "SELECT Branch, MAX(Sales) FROM MonthlySales GROUP BY Branch" totell me what the highest monthly sales figure was, but I just can't figureout how to write a query to tell me which month corresponded to MAX(Sales).Ideas anyone?Cheers,....Andy
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.
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
Can someone please help me with a better way to format the following query. This works, but I know it is hidious.
Code Snippet
select
convert(varchar, processed, 101) as Date, count(o.id) as [# Orders], sum(distinct a.runnercount) as [# Runners], sum(o.total) as [$ Gross], sum(o.fee) as [$ Fees], (sum(o.total)-sum(o.fee)) as [$ Net]
from [order] o join (select convert(varchar,processed,101) as date, count(*) as runnercount from orderitem oi inner join [order] o on o.id = oi.orderid where typeofextraid = 4 group by convert(varchar,processed,101)) a on convert(varchar,processed,101) = a.date
where statemented = @statemented group by convert(varchar, processed, 101) 2 tables: Order and OrderItem. I need the sum of a specific record type from the OrderItem table along with all the other aggregate columns group by day.

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
BEGIN
DECLARE @N1 FLOAT
DECLARE @N2 FLOAT
SET @N1 = ( SELECT DEGERI FROM PARAMETRE WHERE PARAMETRE_ADI='N1')
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,
SUM(BASKAN_TEKLIF) AS YILI,
((100+@N1)*SUM(BASKAN_TEKLIF))/100 AS YIL1,
((100+@N1)*(100+@N2)*SUM(BASKAN_TEKLIF))/10000 AS YIL2
FROM GELIR AS G WHERE YIL = @YIL GROUP BY KOD1, KOD2, KOD3, KOD4 WITH ROLLUP

I am trying to create an aggregate table where the value is a rolling sum. Type a on date 1 is the sum of the values in the main tbl. Type a on date 2 is the sum of values for type a on date 1 and date 2. Is this possible? I have been trying update t sql with sum(case where date <= date) statements but can't get it to run.
create table main_table (type nvarchar(10), date int, datavalues int); insert into main_table values('a', '1',3); insert into main_table values('b', '1',4)
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.
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?
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?
I am trying to display component usage in January for the past year, if I want to display the year in different column, what should I do? eg. component_id component_description qty_used_on_2005_Jan qty_used_on_2006_Jan C58B0BDD tape drive 2 3 Currently I am using this sql: select cast(year(date_complete) as varchar(10)) + ' Jan' as Year, component_id, component_description,sum(component_qty) as total_qty_used from view_jobComponent where month(date_complete) = 1group by component_id, component_description, cast(year(date_complete) as varchar(10)) + ' Jan'order by component_id, component_description which I will get something like this: Year component_id component_description total_qty_used 2005 Jan C58B0BDD tape drive 22006 Jan C58B0BDD tape drive 3
How can I make this stored procedure concept work:
----------------------------------------------- Create Procedure MyProc @MyValue varchar(5) As Declare @ColumnName as varchar(11) Set @ColumnName = 'Price_' + @MyValue Select Sum(Price) As @ColumnName --???? From MyTable where Item = @MyValue Return -----------------------------------------------
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 clustered index in a table. this column is of datatype date. how can i retrieve the following?:
select [date], valueColumn from myTable where [date] = '2000-01-03' and ('2000-01-03'+1) and ('2000-01-03'+2)
My Goal ist to retrieve 3 values of valueColumn of 3 subsequent days, calculate the average of this 3 values and insert this average in a third colum called [average3days].
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?
I am firing a query like:SELECT TaskName, StartDate FROMTasksWHERE StartDate >= '01-Aug-2003'Now the result comes as:TaskName StartDate--------------------------Task1 01-Aug-2003Task5 10-Oct-2003etc.Now what I want is this:Sl. No. TaskName StartDate----------------------------------1 Task1 01-Aug-20032 Task5 10-Oct-2003How do I get the Sl. No. field (it does not exist in the table).Can I do it?-surajit
