.net - More Effecient SQL For Retrieving Thousands Of Records On A Vew?

Oct 5, 2010

I am using Linq to Sql as my ORM and I have a list of Ids (up to a few thousand) passed into my retriever method, and with that list I want to grab all User records that correspond to those unique Ids. To clarify, imagine I have something like this:

List<IUser> GetUsersForListOfIds(List<int> ids)
{
using (var db = new UserDataContext(_connectionString))
{
var results = (from user in db.UserDtos [code]....

Essentially that gets translated into sql as select * from dbo.Users where userId in ([comma delimmited list of Ids])I'm looking for a more efficient way of doing this. The problem is the in clause in sql seems to take too long (over 30 seconds).

Error Filling Dataset During Load Event

May 9, 2012

I am new to asp.net and I'm trying to build my first web page, but when I try to fill a dataset at the page load event I get an error: object reference not set to instance of object. I've done this many times in vb.net. I can't figure out how to step through my code like I do when I'm creating a desktop app, so I don't know exactly where it's failing. I like to be able to see the values of things as it goes through the code.

Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Label2.Visible = False
Dim dsCheckExisting As New System.Data.DataSet()
dsCheckExisting.Clear()
Dim adLookup As New OleDb.OleDbDataAdapter
adLookup.SelectCommand = New OleDb.OleDbCommand

ADO.NET :: Insert New Records In Tables From Dataset To Database?

Aug 27, 2010

I have 2 tables in SqlServer 2008.

Table1: T1id, SomeData

Table2: T2id, T1id, SomeData

I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns
T1id in both tables.

Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.

I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".

DevExpress Generates Thousands Of Lines Of ASP Code / How To Reduce The Code,

Nov 24, 2010

After insert a grid or any other tool into an aspx page it generates enough code for that tool(for ex.): <dx:ASPxGridView ID=ASPxGridView1 runat="server"></dx:ASPxGridView>...

But,after adding any property to this control (like Show group Panel) it generates more than 3000 lines of code in aspx page () and after adding any other tool the code is increasing in a enormous way...

How can I reduce the code, maybe there is a property(settings) in DevExpress option...
