DataSource Controls :: How To Create INDEX For A Table
Jan 10, 2010
I single table in SQL Server having 50 columns col_1 to col_50 having type varchar(MAX)..The table is having nearly 2 crore data into it which is unstructured i.e. just put in by bulk copy. I have to perform search operation on this table. How to index the table so as to make the search fast? or any other way to make the search fast.
Cannot create the clustered index 'RateViewIndex' on view 'NoteToPass.dbo.RateView' because the select list of the view contains an expression on result of aggregate function or grouping column. Consider removing expression on result of aggregate function or grouping column from select list.
<asp:sqldatasource id="SqlDataSourceX" runat="server" connectionstring="<%$ ConnectionStrings:MyConn%>" providername="System.Data.SqlClient" selectcommand="SELECT ItemNum, MIN(DateAdded) as [DateAdded] FROM Items WITH (NOLOCK) WHERE [DateAdded] between @DateFrom AND @DateTo
[Code]....
When I call select in codebehind, after 30sec it throws timeout expired SqlException:
[Code]....
again , this select took up to 3 sec to be executed. In application I tried to use SqlConnection and SqlTableAdapter instead of SqlDataSource, with the same query, and again it took up to 3 sec.
If I choose tighter interval (e.g '2011-01-20 00:00:00' - '2011-01-21 00:00:00') , there is no timeout exception, so I know that sqldatasource select is executed correctly. So the conclusion is that sql server is not using index while executing query sent from sqldatasource, but is using index whenever else. I have also checked the index statistics on sql server and it is like that. In profiler i can see slight difference between this two cases. As for SqlDataSource, in events table, in first column "EventClass" after 30 sec, there is this: "RPC:Completed" and application throws timeout. If i use SqlConnection and SqlTableAdapter then at the same place there is this: "SQL:BatchStarting" and "SQL:BatchCompleted" and application does not throws timeout(the index has been used).
what is so special on SqlDataSource connection, that Sql Server performs differently compared to other types of connections?
I'm assuming I need to use a pivot table from what I've found so far. However, every one that I've seen has not had the date setup like I have.
I have a Gridview on my page which I need to be populated like so
Date NCMR
1/1/10-1/31/10 #
2/1/10-2/28/10 #
I want to do this for 10 months... bottom record being the current month (or last month). I would also like the Date to format to January 2010 I used the above date format because that is how it is in the table. Basically, I need to know how to create the pivot table to search the table for 1/*/10, 2/*/10, etc
I have ASP.NET enviroment (C#) with SQL 2008 backend. I am using the ASP.NET membership provider. I need to create a table that contains member name, member role and third coumn (called "Registered for Conference"). I am using a button to initiate the action to call a stored procedure to write the selected value in the "Registered for Conference" column for the respective member.I know how to write the stored procedure, how to determine which user has processed their selection and how to write it to the "Registered for Conference" column of the table.I know that I can pull member name and member role with the following statement.
SELECT dbo.aspnet_Users.UserName, dbo.aspnet_Roles.RoleName FROM dbo.aspnet_Roles INNER JOIN dbo.aspnet_UsersInRoles ON dbo.aspnet_Roles.RoleId = dbo.aspnet_UsersInRoles.RoleId INNER JOIN dbo.aspnet_Users ON dbo.aspnet_UsersInRoles.UserId = dbo.aspnet_Users.UserId
I need to understand how to create the table that will contain the member name, member role and third coumn (called "Registered for Conference"). This table cannot be a static table. In other words, this table needs to refect any updates to roles or members
I have a strange issue. I have a XSD file where I have created some TableAdapters. When I have reopened the XSD file it seems like I am not able to create a new table adapter since all the options which will come when I right click on the XSD file are disabled. I have cross verified whether I am on debugging mode but...I was not..(I am not even able to drag and drop an adapter from the left toolbox menu either)I am getting the same issue when I open the same XSD file on somebody else machine but I am able to create TableAdaperts in other XSDs.Can somebody suggest me a solution for this
I have read up on uploading multiple images and storing them to a file but so far i am only able to store one image into both file and into database. The problem i have is that i don't know how to create the table to store more than one image?
I have an ID column (int) in my table which also needs to be a unique key.
last time I worked with a database (BD2), I set this as an autoIncrement feild and it would automaticaly 'deal with it' (ie, maintain the last used value somewhere and automaticaly used that value (after incrementing it) for any new row on the table).
How do I handle this in ASP.NET. Especially, as I try to add a new line based on form content when the user presses on a button (C#).
I have a table that contains item data. If the item is a particular type further information exists to describe the item. The additional information isn't that heavy however the number of records in relation to the main file will be quite small (less than 5%).
So I have 2 scenarios:1) Put the additional data in the main table and take tha hit on storage
2) Create an additional table and link the 2 together
If we were talking huge amounts of data I can understand that 2) would be the obvious choice but given the simplicity should 1) be a consideration?
If 2) is the answer - is it possible to create a dependency between the 2 tables when the item is 'that' particular type. In other words wnsure the addition data is populated for the required items and not others.
I am trying to use SqlDependencyCache buthave come across a problem that I wouldn't have thought was unique. We have a InformationDatabase which uses a combination of its own tables and views to other databases on the same server. One of these views points to our HRDataWarehouse database. My stored procedure obviously uses this view to get its information but because the table change is happening on the HRDataWarehouse table the notification is not being sent to my app and as a consequence the cache is not removed.
Is there a tidy way of doing this or do I need to create a trigger to update a table in my informationdatabase and then have a listener on this with a removecache callback delegate added to the cache object?
More specifically, i'm trying to create a stored procedure that displays data from a table if the date column in the table matches a specific day of the week. (IE. Monday, Tuesday, ect...)
I have not been able to create a function to take a long nvarchar (8000) with a delimeter to return the results in a table . I have a script version that works as a query. I plan to use the Function in a Select * FROM table WHERE FirstName IN dbo.ListOfItem(@InputList) Is the following posible in SQL Server 2005?What is wrong with syntax? Is there a better solution?

The goal, from internal department (user) perspective:A department wants to "upload" an excel spreadsheet of data (product, term, rate, etc) to SQL (this will be from the internal network). The data is then saved to a webpage location for that department to view and approve. Once "approved," this data is displayed on the live web servers (public-facing website which is two load balancing servers). Bonus:
The .NET application/SQL Server can send an email to the department reminding them to upload the latest rates (each weekday morning, then each Thursday afternoon) if rates have not yet been "approved."
From the development perspective, this is my general idea, but I may be wrong.There are three spreadsheets, each with one tab. The first spreadsheet is uploaded, and the .NET application puts it in a SQL table. I then need to display this table of data on a .aspx page for the department to approve before the .aspx page is pushed to the live web servers.
First, I need an interface for this department to upload Excel files. I need this application to save the data to SQL and display it in a .aspx page so that the department can look it over and approve it. The department needs a way to "approve" the page, and this action will push the data to the live web servers. Will this involve SQL data transformation services?
i am facing a problem to get a correct row index after i filter the data in table, it always keep the history row index in the table before i filter. i had a search button to filter the data in gridview,
I´m looking for some advice on how to create an table showing bookings, a table containing mon-sun on the horizontal axis and times at the vertical. The admin is able to edit each days bookable times (first bookable time, last bookable time) - The slottime is constant.
What I want is let the admin click on eacha cell to remove it/add it when removed. And other features as well, like create an booking for a customer.
What would be the easiest way to achive this, at the moment I use dynamic links since I cant get asp:buttons to work and the code to create an dynamic asp:table row by row and this produces some ugly code.
So any advice on how to achive such an "schedule".
