SQL Server :: Sub Query In Cross Table Query To Create Statistics
Mar 2, 2011
I am trying to create statitics for game downloads and am having dificulty with a sub part of my query. the goup by command is not having the disired result and i think i have been looking at it too long to see what i am doing wrong. [Code]....
At the moment it is producing each result in many rows when only 4 rows should appear. its the download column that is doing it. needs to be sub queried or something to display total in relation to month,gameid,userid.
A follow up question concerning the DAL layer part .. The first question about dealing with large objectsI have one table (PlacesTable) that is connected by like 6 other tables (1:Many and Many:Many relations)
In my DAL should I put a big query that join the 6 tables + the m:m reference tables (btw it produces multiple data that I don't need Please refer to my old question) and place all the data in it's specific object property or, should I use a single query for each table and create an object for each fetched table .. and finally send those to the UI ?If I wasn't clear enough please let me know what I further information do you need to know!
I have a basic Linq query and what I need to do is query the DB then display the data in HTML.Typically I would bind this to a control but in this instance I need to actually generate the HTML in the code behind page.The Linq query is very basic something like this with Northwind:[Code]....
Instead of binding that to a gridview how can I write out the html... I'm sure I can use stringbuilder or smilar to create the html but I'm not sure how to get he data in the tables... foreach datarow in?
how to create sql query and display one element of that table in view? every example on the website demos controls that add big tables of data. that's useful like 10% of the time. how about displaying one element from a query?
By right clicking on my database i created a query in server explorer. But where are this query stored can't find them back. I should aspect that their is a folder query's like there is a folder tables but this isn't the case.
I am trying to display this query result in an aspx page.
It is very slow in loading. Here is the query. The inner query inside the outer quesry is the problem.(Please see the underlined part in the query) - (If I remove that part it is very fast.)
select
top 500
--This column is the issue ,Governing_Class=( case when exists (select top 1 tqc.class_code from t_quote_class tqc inner join t_quote_class_premium tqcm on tqc.class_code =tqcm. class_code where tqc.appid=pi.appid and tqc.class_code not in('8742' ,'8810','7380') order by tqcm.premium_amt desc ) then ( select top 1 tqc.class_code from t_quote_class tqc inner join t_quote_class_premium tqcm on tqc.class_code =tqcm. class_code where tqc.appid=pi. appid order by tqcm.premium_amt desc ) .........

I am a biggner in SQL DB . but i started a complicated and painfull work in SQL SERVER 2008. the problem convert Oracle hierarchical query to SQL query. the query
SELECT DISTINCT LEVEL LVL, SCH.NSCHEDULE_SL, SCH.NSCHEDULE_SL_FM, SCH.CSHED_CNAME FROM FA_SCHEDULES SCH WHERE LEVEL = 1 AND NSCHEDULE_SL_FM IS NULL AND NBRANCH_SL = 2 CONNECT BY PRIOR SCH.NSCHEDULE_SL_FM = SCH.NSCHEDULE_SL AND NBRANCH_SL = 2
I have partitioned a table and it has been partitioned according to an account id. ie also rows that have accountid =1 will be in A partition and all rows that have accountid = 2 will be in B partition. so now if i execute a query with where condition accountid =1 sql server will search only in A partition. Suppose if i add another condition to it ie where accountid=1 and place="aaa" will this query search only A partition or the entire table?
I have inherited a very old SQL Server Database for a live site, but have been asked to add a new table for invoice recording to it. Fairly easy to do for any new record added from now on, however I run into some issues with selecting older records.I need to find a way to select from 3 tables, see if a record exists in the new table and if not insert a new record to it.My stored procedue so far is (The new table is [Invoicing]:
I am looking for simple asp.net code example showing a simple webform task.
When user clicks a button, a stored procedure fires which runs an update-table query (not pulling any parameters from the user) and returns a count of the number of rows that were updated when the query was run.
Within my stored procedure I have the parameter @RowCount=@@ROWCOUNT.
All sample data I have found online has been C# or VB, but nothing that I can apply to my asp.net program.
Again, this is a simple task that for whatever reason I cannot find examples of online.
I'm using this code for creating and xml file out of a SQL2005 table:
[Code]....
Is there a way for me to create multiple xml files, one for every row, going by the primary key column, or do I have to create a separate query for each row?
I would also wondering what is the syntax for transforming this query into a stored procedure
In my query I want all departments and employees listed who work on a particular date. In addition, if the Department.Include_Unavailable is 'true' I want to create a row with the department and employees who work in that department even if they are not schuled to work. I will eventually list these employees as 'unavailable' but do not want to list all unavailable employees as unavailable. Only employees that work in departments that have Department.Include_Unavailable set to 'true'
I have one Store Procedure that generating report ..
For storing the data there , i used many temp. tables. There is many Select Query , little less insert and delete query.
Now if there is huge data around 1 lac in temp table my select query taking to much time and also may be insert and delete query
I added Primary key to all auto Increment Field in temp table. Also defined Clustered index on that primary key as unique Clustered index to improve the performance .
But there is not so much improvement in case of huge temp table.
Right now the whole Store Procedure is taking time to complete around 1.5 days or around 30 hours ..
So i want to increase the performance as much that it completes on nearly 3-4 hours.
I'm implementing a BLL layer and have a few questions. First, in my DAL, there is a contacts table, the select method is a sql query against a sql server 2000 database. The preview data returns everyting as expected. The query is
[Code]....
The BLL method is built like so
[Code]....
When using the BLL method to a gridview, the results of the subquery are not displayed. There are also other methods, each having a different where clause for ContactRole_ID and each is having the same issue of not displaying the subquery reult in the gridview. No error, but no data is displayed for the subquery either. Here is the templatefield of the gridview
[Code]....
Another item that is causing an error is in trying to update a record. Here is the DAL update method
[Code]....
And the BLL update method
[Code]....
The error says i have extra parameters, but have no clue where the extra parameters are being picked up. The error isObjectDataSource 'odsContacts' could not find a non-generic method 'UpdateContact' that has parameters: _ContactID, _Active, _ContactName, _Office, _VirtualOffice, _Pager, _Fax, _Home, _Cellular, _Email, _ContactRole_ID, Active, ContactRole_ID, ContactName, Office, Email, VirtualOffice, Pager, FAX, Home, Cellular.And the objectdatasource
