Return sum of 2 subsets to single SqlDataReader?

Hi,

As far as I understand the ListView-Control and the DataPager-Control, they work like this: The ListView gets its datarows from its data source, then the DataPager causes the ListView to display only a subset of those rows.

So what, when I want to use custom databinding for the ListView, that *already* gets the certain subset from SQL-Server (for better performance). Can I and how can I use the DataPager then?

Thanx, S.

Hi.

I have the below SQL which works just fine:

SELECT     Message, CreateDate, AccountId, AlertTypeId
FROM       dbo.Alerts
UNION
SELECT     TOP (100) PERCENT Status, CreateDate, AccountId,
                          (SELECT     10 AS Expr1) AS AlertTypeId
FROM         dbo.StatusUpdates
WHERE AccountId = PassedInParameter
ORDER BY CreateDate DESC

I have been going about trying to convert the above into a LINQ method and am having problems with return types.
As the above SQL illustrates, I am querying two distinct LINQ tables - Alerts and StatusUpdates -
and then attempting to perform a Union on them. In order to do the union in LINQ, I have to have agreeing types. So, I
am using "var" to make the results of "alerts" and "updates" generic before the union.  

public IList GetStatusUpdatesAsAlertsByAccountId<T>(Int32 accountId)
        {
            using (WorkbookDataContext dc = _conn.GetCont

 i have a stored procedure which returns three tables to a dataset ..... now i need to merge all three tables to a single table from d same dataset 

like dataset1 has table1 table2 and table3 .... i want all the three tabels to be merged into dataset1 itself .... instead of three diffrent tables so that i can show all three table data in a single datagrid  as a compact data and combination of 3 tables from d single dataset.....

can some1 help me please.....

I am trying to run a stored proc from this function. When I run it thorugh the debugger I can see that myReader.HasRows = true and myReader.FieldCount =14.

But the control does not go in the loop while (myReader.Read()) where I am trying to read Version field returned by the stored proc.

Pls check me code and suggest correction. Thank You.

private static int Get_CaseInfo(string CaseNum)
        {
            int Ver = 0;
            String myConn = ConfigurationManager.ConnectionStrings["DBConnectionString"].ToString();
            SqlConnection conn = new SqlConnection(myConn);
            SqlCommand cmd = new SqlCommand();
            cmd.CommandType = System.Data.CommandType.Text;

            SqlDataReader myReader = null;
            String stmt1 = "EXEC [REPORTS].[CaseInfoByCaseNo_Get] @CaseNo = '" + CaseNum + "'"; 
            cmd.CommandText = stmt1;
            cmd.Connection = conn;
            try
            {
                conn.Open();
                myReader = cmd.ExecuteReader();
                while (myReader.Read())
                {
                    Ver = (int)myReader["Version"];

                }
            }
            catch (Exception)
            {
                throw;
            }
            return Ver;         
        }

I have a simple asp with the following code.  When I access this page directly (via browser) everything works fine:  the xml object shows up fine.  When I call this page via VBA (excel), the ResponseText method of the 

XMLHTTP object returns the below code unexecuted.  Anybody knows what's going on?  thanks.

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>



<%
     
    
    Response.Buffer = True
    Response.ContentType = "text/xml"

    Dim oDataXML As Object                    'Custom Data XML passed in by caller.

    On Error Resume Next

    'Load the XML passed into the request.
    oDataXML = Server.CreateObject("Microsoft.XMLDOM")
    oDataXML.Load(Request)

    Dim sResult As String
    sResult = "<?xml version=""1.0""?>"
    sResult = sResult & "<OrderProcessed>"
    sResult = sResult & "<Status>test</Status>"
    sResult = sResult & "<OrderID>111</OrderID>"
    sResult = sResult & "</OrderProcessed>"
    Response.Write(sResult)
    Response.End()

I am using fluent NHibernate with WebForms and I am trying to build a page where I allow a user to post a status update on their profile page and I a using a .asmx WebService to post the data to the database and then returnig a StatusUpdate instance to the page to be used by jQuery. I have a couple problems.

1) First off when I return a string from the WebService(i was testing) the textbox where the user enters their status doesnt empty the contents. And since the page doesnt refresh even if I manally clear out the textbox and put in something else, it still posts the previous status to the database again. How do I fix this?

2) Secondly, when I return the StatusUpdate Object from the Webservice I cant the results to display anything. Like I sad, Im using jQuery to make an AJX call to the WebService.

Here is my code:

User Profile Page:

<p>
Status: <asp:Label ID="status" runat="server"></asp:Label><span style="font-size:.7em;"><asp:Label ID="statustime" runat="server"></asp:Label></span><br />
<textarea id="statusBox" rows="3" cols="40"></textarea><br />
<input type="button" value="Update Status" onclick="SetStatus(); return false;

Rich clients employ many of the features and conveniences of the operating system they run on, and the list of these features has been growing since the dawn of the PC. But as apps have migrated to the Web, the trend towards increasing client-side functionality has ground to a virtual halt. There are several reasons for this; chief among them are security and deployment problems. But that's all about to change. With the .NET Framework, you can participate in building the distributable rich client of the future. In this article, the author enumerates the pertinent features of .NET that will allow you to build safe, easily deployable controls. The features discussed include managed code, code access security, versioning control, Windows Forms classes, and isolation.

Front-end developers frequently want to add functionality to the presentation tier of an n-tier architecture, but such requests can require changes on all tiers just to get the data and present it. This process can be made easier and more flexible by using SQL Server stored procedures to automate the delivery of data in XML format from the database to the front-end components. In the component presented here, stored procedures are invoked by XML strings, XML is returned, converted using XSL, and presented to the client in HTML. The technique supports rapid changes yet doesn't sacrifice the n-tier approach. This approach can be used with either SQL Server 7.0 or SQL Server 2000.
