Forms Data Controls :: Delete One Duplicate Record Of Many Duplicate Records

Mar 15, 2010

I have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.

I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:

I used the following query to load in duplicate records:

SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))

ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006

What is the query to delete single duplicate record instead of deleting all duplicate records?

Avoid Duplicate Items When Databound Control Gets Bound Twice?

Feb 1, 2010

How do you avoid duplicate bound items in this scenario: There's a databound control on a page (a DropDownList in this case, though I don't think it matters). It has AppendDataBoundItems set to "true". Somewhere in the code, a DataSource is set and DataBind is called. So this control is bound explicitly. You have a bunch of other things to bind on the page, so you call Page.DataBind.

Your databound control now has duplicate items in it. It was (1) bound explicitly, then (2) Page.DataBind bound it again. Since AppendDataBoundItems was true, the second bind appends to the first, and you end up with double the items. A couple limitations: The explicit call to DataBind on the control is done through some centralized code, and would be painful to change. i really need to bind the rest of the page in aggregate (via Page.Databind()) because there's too many other databound elements to do it individually without writing a ton of individual calls.

I need a method like... Page.DataBindExceptIfTheyHaveAlreadyBeenBoundDuh()

Forcing Https And Avoid Duplicate Urls Using IIS7 Url Rewrite Module

Feb 16, 2011

I need to force every request to https://www.mysite.com (always with https and www)

The site is hosted in GoDaddy and I need to do it via IIS7 URL Rewrite Module.

I've been able to do the HTTPS redirect with the following code:

<system.webServer>
<rewrite>
<rules>
<rule name="Canonical Host Name" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^mysite.com$" />
</conditions>
<action type="Redirect" url="https://www.mysite.com/{R:1}" redirectType="Permanent" />
</rule>
</rules>
</rewrite>
</system.webServer>

Test cases

http://mysite.com -> https://www.mysite.com OK
http://www.mysite.com -> https://www.mysite.com NOT WORKING

I guess the condition is not being satisfied when I enter www.mysite.com in the browser, so there's no redirect and the page serves as HTTP instead of HTTPS.

I think I just need to modify the condition pattern, but I have almost nothing regex knowledge and I need this asap.

Duplicate Records While Insertion Into Grid?

Mar 22, 2011

I have a page which consists of a grid and add new button. When the user clicks add new button he gets several fields to be entered. So, when he clicks submit I usually write a query which checks if there is an entry already in the database. In this case, I succeeded. However, my task is to also show the records identical and let the user decide to proceed or not.SO, I am not sure of how to proceed with this one. So, can anyone just help me in giving an idea on how to proceed with this one?

ADO.NET :: Duplicate Records Using Join In Linq To Entities?

Aug 5, 2010

I am having trouble with duplicate records. I tested .distinct() in several areas and nothing helps.

I got the search criteria from the PreviousPage. I then used this criteria to search QueryA.

I did a search using QueryA. I took the results, and put the IDs into an array.

I then did a search using QueryB, that matched the IDs in the array. QueryB is used for the ListView and to page records.

Using test records. QueryA results = 2 records. The array.length = 2. QueryB results = 3. ?

What am I doing wrong ?

Some of my Code:

myResults = (from r in QueryA
select r.ID).Distinct().ToArray();
totalrecords = myResults.Length; // = 2
using (ToHealthEN n = new ToHealthEN())
{

C# - SubSonic .Paged() Query Returns Duplicate Records

Feb 8, 2011

Using a SubSonic (2.2) SqlQuery object, I am querying a view that contains distinct rows from another table. The results of the query, however, contain multiple rows for certain rows in the view. It appears to be because of a join on a temporary table in the query generated to achieve paging. How can I avoid this duplication of rows?

Bonus points: I have to use the view because SubSonic can't do .Paged() and .Distinct() at the same time. Why not?

DataSource Controls :: Deal With Insertion Of Duplicate Records?

Jun 10, 2010

I need to write a sql script which will scan for records in a table (Table1) and thencopy the records found into a second table (Table2). Table2 has the same table structureas Table1Table 1 has a primary Key for the first column named CustIdI thought this would involve A simple sql statement like:

INSERT INTO Table2
FROM Table1
SELECT *

However I just realized that if A record already exists in Table2 and I try to inserta duplicate record into Table2, how should this be handled?Should I instead use an Update statement without a where clause?
