Problem querying SQL data

Posted By:      Posted Date: October 27, 2010    Points: 0   Category :ASP.Net
 

I entered the following C# code in my button-click event handler of a web form:

        DataClassesDataContext db = new DataClassesDataContext();

 

        Profile profile = db.Profiles.SingleOrDefault(p => p.Callsign == Textbox1.Text);

 

Both the 'Single' and 'SingleOrDefault' statements result in the following error message:

'System.Data.Linq.Table<Profile>' does not contain a definition for 'SingleOrDefault' accepting a first argument of type 'System.Data.Linq.Table<Profile>' could be found.

Also, is it permitted to refer to textbox text as the condition for selecting a row in the table?

weird problem of using multithread to querying sql server

  
Hi,   I'm working on a project which needs query the sql server many times to pull the statistics info. the whole process is very slow. so, I'm trying to use the multithread to do the work. However, I noticed one weird thing:   In the program, I need pull, say 10000 documents from the sql to local PC, then can do some analysis. Each document size is different. If I used 1 thread, say for document A whose size is 5MB, it will take about 20 seconds for the SELECT query returns the result. Now, if I used 10 threads, I found that it will take much longer time for SQL to return the SELECT query for document A, say maybe 90 seconds. I got the run time for the SELECT from the sql profiler.   Overall, the performance of multithread is very similar to single thread even I use 50 threads. I used the same code for another project, the only difference is that that project scrapes data from website and this project gets data from sql. The other project works very well when using multithread. so, I'm kind of believe that the multithread part code works fine.    Could this because some settings on sql server? some bandwidth limitation? any clues?   any help/suggestion will be appreciated.   thanks reader      

wpf charting column series data binding problem

  
I'm trying to build a chart using the columnSeries from the wpf toolkit and I appear to be having trouble with the data binding. Here is the xaml: <Grid>    <chartingToolkit:ColumnSeries Height="18" HorizontalAlignment="Left" Margin="188,169,0,0" Name="columnSeries1" VerticalAlignment="Top" Width="18" IndependentValueBinding="{Binding Path=Date}" DependentValueBinding="{Binding Path=Value}" /></Grid> In the code behind, I'm calling a stored procedure and putting the result in a datatable like this: string connString = ConfigurationManager.ConnectionStrings["string"].ConnectionString;            using (SqlConnection cn = new SqlConnection(connString))            {                DataTable dt = new DataTable("T1");                cn.Open();                SqlCommand cmd = new SqlCommand("T1_sp", cn);                cmd.CommandType = CommandType.StoredProcedure;                  SqlDataAdapter da = new SqlDataAdapter(cmd);                da.Fill(dt);                columnSeries1.ItemsSource = dt.DefaultView;                cn.Close();            } No error is being generated but I'm not getting a column chart either. If I take the same command and put it into a datagrid, it works fine. What do I need to do to get this into my column chart? If it helps,

XML data type in SQLSERVER 2000 for querying

  
Hello,   we’ve developed an application that uses a database with a XML data type column. It works fine with SQLSERVER 2005 an above, but we cannot create the structure in SQLSERVER 2000 because it doesn’t support that data type.   We’ve made some test with SQLXML 3.0 packet and SQLSERVER 2000 but it only adds pseudo-support to work with XML documents. We need to store XML documents into a column and then make selects using XPath sentences over that column. For instance: select * from users where description.exist('//info[@value = "francesc"]') = 1 Is there any way to achieve this using SQLSERVER 2000?? Thanks in advance! Francesc

Data Driven Subscription problem - sub runs slowly, has 40 errors out of 300, but report server trac

  
I have two report servers and a single separate SQL Server 2008 server hosting the data source database and the report server catalogues. There is a data driven subscription that runs off a sproc that returns 300 rows with email addresses for this report to be emailed to. The report itself contains around 30 subreports each with its own sproc to retrieve data. As the report is executing there are long pauses between the times when emails are actually sent out, and the subscription status will finally end with something like "Done: 300 processed of 300 total; 40 errors." I am not sure how to go about troubleshooting this problem. Details: I kicked it off at (say) 2:00 PM. Within 3 minutes in the report server execution log I saw 300 entries. There were exactly 300 people who should receive reports, so the master report should have executed 300 times and sent out 300 emails. So this looked good in the execution log. But when I checked report manager's status page for the subscription it was listed as processing 50 out of 300... Then all activity stopped, about 15 minutes some more reports started emailing out, and now I see there are around 590 rows in the execution log and maybe 97 emails sent out... Then finally I get a grand total of 846 rows in the execution log and a grand total of 260 of 300 emails sent out with 40 errors so 260+40=300 exactly. The time betw

Business Data Connectivity Services Problem

  
I'm having problems getting Business Data Services to work. When I go into: Central Administration -> Service Applications -> Business Data Connectivity Services I get the error 'keyset does not exist' I've been doing some reading and come to the conclusion it's something to do with authentication? We use NTLM authentication and I'm wondering if we need to set up sharepoint to use kerberos. Does anybody know about this problem? Thanks
