DataSource Controls :: Select Distinct With Where Clause Don't Work?
May 2, 2010
I'm using asp.net login on a SQL Database.
I have 12 users in my User tabel - one of the user I don't want to have in my select (the user is an admin).
I tried this:
[Code]....
I also tried:
WHERE (dbo.aspnet_Roles.RoleName <> 'Administrators')
Both time it took the user into the table....
If I instead try this
WHERE (dbo.aspnet_Roles.RoleName = 'Administrators')
I get only one row (as expected).
What is wrong with the above sql statement - why can't I get 11 users and not them all (12 users)?

<
asp:LinqDataSource
ID="LinqDataSourceSM"
runat="server"
ContextTypeName="SalesIntranetSolution.DataClasses.salesIntranetDataClassesDataContext"
OrderBy="reportTo"
Select="new (reportTo)"
TableName="cubeSalesRepRollups">
</asp:LinqDataSource>
Does somebody know how I can modify this LinqDataSource to select distinct records only?

there are multiple rows with same SubContact_No and with same value of some columns. for a single column I am firing query like
Select distinct (Financial_Status) from mtblSub_Contract where SubContract_No=@SubContract_No";
it's working fine.... (it's ok with a Single column)
But Now I need multiple columns value so how to query for this.
Select distinct (Financial_Status, colums2, column3) from mtblSub_Contract where SubContract_No=@SubContract_No"; is not working
So how to do that.

I would like to select a distinct query based on three fields and display the rest of the fields. For example,
I have firstname, lastname, address, city, state and zip, but I only want to use the distinct on these fields first and last name. However when i use the distinct function I get a distinct on all the selected rows. I just want to distinct firstname and lastname and display the other fields. for example,
Mary Smith New York
Mary Smithy New York
Mary Smith Maine
I would like the result to be:
Mary Smith New York
Mary Smithy New York
I don't care about Mary Smith Maine, because i am only using the distinct for "Mary Smith" firstname and last name and showing the city.

Iīm a newbie at .NET and Iīm trying to solve how to run a datagrid with parameters. I know how to do where clauses with controls and today I managed to solve how to have a where clause at UserID within a SelectingEvent.BUT, I canīt run them both in the same time. I want to run a query based on the month in a dropdownlist and the UserID. Each one individually works.Why canīt this be done? Is the onselect statement ignoring the other parameter? I donīt get any errors.The ASPX (in VB.net) code is:
<%@ Page Title="" Language="VB" MasterPageFile="~/Site.master" AutoEventWireup="false" CodeFile="IndividuellBonus.aspx.vb" Inherits="Income_IndividuellBonus" %>
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" Runat="Server">

This is not giving me the wanted results.
Two models:

Each ContentVersion is linked to Content through the ContentID.
I want to select all "Content" where UserID = X, then for each selected "Content" I want the latest "ContentVersion".
The return type should be of type <IQueryable>ContentVersion.

I am having difficulties using a variable in the "where" clause:
declare @shift_started as datetime
set @shift_started = (SELECT *
FROM OPENQUERY(ADS_RGWP_SERVER, 'SELECT MAX(shift_started) as shift
FROM salestkt AS STK
WHERE NOT EXISTS(SELECT *
FROM SHFTDATE AS SD
WHERE SD.shift_started = STK.shift_started)'))
SELECT *
FROM OPENQUERY(ADS_RGWP_SERVER, ' sum(case when customer_type = ''Inter-Company'' then qty_shipped_today else 0 end) as intercompany_qty,
sum(case when customer_type = ''Charge'' then qty_shipped_today else 0 end) as outside_qty
FROM salestkt
WHERE shift_started ='" & @shift_started & "' ''')
Getting error:
Incorrect syntax near ' & @shift_started & '.

This is something I can easily do in SQL, but I'm pretty new to LINQ and haven't been able to find an answer online.
I need a LINQ query that returns two values; the first a distinct value and the second the count of the first value. This is filtered by a parameter. Here is my table:

I have an SqlDataSource query that should use an input parameter for multiple integer values, like:
select * from table1 where TableID IN (1,2,3,4,5)
->
select * from table1 where TableID IN (@IDValues)
How do I do that ? Default parameter settings won't work, returning "invalid integer value" . I suppose that parameter should be passed as some kind of array that SQL recognizes as multiple integer values , but what's the correct way of setting this ?

I have a GridView that's currently bound to an ObjectDataSource. I would like to see if it's possible to instead bind it to an EntityDataSource. However, I need to be able to apply custom filters to it.
One of the filters corresponds to a bit / boolean property in the database / EntityDataModel. It has 3 possible selections:

How can I accomplish the same thing in an eSQL Where clause? There is no COALESCE function, is there an equivalent?

I am using Linq to SQL. Tables have timestamp columns and I am using regular Linq methodology in ASP.NET MVC.I do use detached entities and always try to do updates without first querying the database for the original entity. To update an entity I use context.Attach(entity, true) followed by context.SubmitChanges() and all is fine. The sql statement that gets executed looks like:

Here is the query I have now which returns over 2 million records:
[Code]....
This works, but the result is littered with many rows that contain the same SSN. So how do I return only one row for each ssn? I cant use distinct because all of the other columns are already always different, this would return the same as above.
