I have to following Linq query, where I look for some different timestamps in an DB:
[Code]....
My problem is that I would like to filter the query, to only return entries, where OutOfOrderStart and OutOfOurderEnd is from the same row. How can I accomplish this?
I have a table with Id, Name,...IsActive, etc. If user wants to delete a record from the user, he/she should update the field IsActive to false. I am able to acheive this functionality using the below steps,
1. Query the database for the row which is to be updated.
2. Update the property IsActive to false.
3. Submit the changes to the database.
This way i am successful. But i have a query here is that, when we execute steps 1 and 3, there will be two trips to the database for getting the required object and again updating the same object to the database.
Is this not a performance hit having multiple calls to DB for a simple operation.?
Do we have any other go, where in within a single call to database, can i update a field of row?

My question is that, for each control the Stored Procedure called or not? If it is yes then it is time consuming and I need to use LINQ to DataSet or LINQ to Object rather than to call SP for each control. What is difference between LINQ to DataSet and LINQ to Object?
Existed MyControl1.Controls.OfType<RadioButton>() searches only thru initial collection and do not enters to children.
Is it possible to find all child controls of specific type using Enumerable.OfType<T>() or LINQ without writing own recursive method? Like this.

IEnumerable<Customer> filteredCustList = from customer in custObject
select customer;
filteredCustList;
}
GridView2.DataSource = utilLinqClass.GetCustomers();
GridView2.DataBind();
(no errors at build time or at compile time) Error I am getting is: An attempt to attach an auto-named database for file App_Dataaspnetdb.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

I created a database on SQL Server 2005 developer edition with MS SQL Server Mangement Studio Express. Now I created code that accessess a stored procedure named 'pS_TableData'. However I have one problem the code raises an exception "Could not find stored procedure 'pS_TableData 'Letters''."the code looks like this:
[Code]....
Note I am using (for now) the same connection that I used to create my database so in essence my web site is the administrator. I tried a simple SELECT from a table with the same connection and it raised no exceptions!When I run EXECUTE ps_TableData 'Letters' in SSMS it has no . I also tried EXECUTE ps_TableData 'Letters' as the command paramated for SqlCommand but it had the same effect
I have to write a stored procedure to get the biggest two values out of three in three different columns in the same table.
I have a table , for instance,
total marks1 - column1 ( eg values - 1000)
total marks2 - column 2 (eg values - 500)
total marks3 - column 3 (eg values - 800)
i have to get (return the value) 1000 and 800.
best Way to find out if record exists?

View 3 RepliesI have a Windows 2003 test server hosting an asp.net 2.0 application and Sql Server 2005 running as Sql Server 2000(80).During a recent a security review we decided that it wasn't such a hot idea to use sql authentication with an sysadm user as the database user for the asp.net application. Having done a bit of reading (http://msdn.microsoft.com/en-us/library/ms998258.aspx#pagguidelines0001_dataaccess) I decided to use a lower privilege database user account and windows authentication.Starting from scratch I created a new custom service account (http://msdn.microsoft.com/en-us/library/ms998297.aspx) and assigned this to the process identity for the application pool.I then created a new database login and user for this account. I added the db_datareader and db_datawriter roles to this user and I also granted EXECUTE permissions for user defined stored procedure and functions. However when I started the application I got this error 'User does not have permission to perform this action.Cannot find the object 'AspNet_SqlCachePollingStoredProcedure', because it does not exist or you do not have permission.' - after a quick hunt I found thishttp://forums.asp.net/p/1487216/3493362.aspx and followed the advice herehttp://msdn.microsoft.com/en-us/library/system.web.caching.sqlcachedependencyadmin.aspx and granted the user CREATE TABLE and CREATE PROCEDURE permissions.Still no joy - after digging around and looking at sql profiler I found what I believe to be the offending piece of sql:
/* Create notification table */
...sql
/* Create polling SP */
..more sql
..finally
GRANT EXECUTE ON dbo.AspNet_SqlCachePollingStoredProcedure to aspnet_ChangeNotification_ReceiveNotificationsOnlyAccess
My understanding is that to issue 'GRANT EXECUTE' the user must db_owner or db_secadmin. Indeed it all works fine if I give the service account user login the db_owner role.This sql is caused by: SqlCacheDependencyAdmin.EnableNotifications(ConnectionString), this is called once and once only by the application start event.Is there a work around for this? I would like to use the lower privilege account as per best practice but this issue is making it tricky.
I think that type of data types is really smart.and hope some can help me with something more.I could not find any links about it.Right now, I can only make a getdata (), which shows all data:
