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?

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?

I have code for inserting a record into the db, it works fine from the admin part of my website but when i put it on the customer side duplicate records are inserted into the db, any ideas?

I want to display all duplicate records in the table.My query has to fetch all the records which are duplicate(First Name or Last Name).Also I want the ability to also pull names where there might be a middle initial placed in the end of the first name field, (i.e., "Maria Z. " vs. "Maria") as well.
Table:
ID FirstName LastName
1 Zach H Hoffman
2 Zach Hoffman
3 Troy Hoffman
4 Shawn Livermore
5 Prem S
6 Jony Hoffman H

ID FirstName LastName
1 Zach H Hoffman
2 Zach Hoffman

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())
{

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?

I've got a linq to sql query that pulls data from 2 different tables and contains an or statement:
[Code]....
The problem I've got is that some queries match both sides of the or statement so it returns the same record twice.
How can I eliminate these duplicates quickly and easily?

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?

I have some duplication that I need to clean up. I wrote a SQL query that is supposed to return duplicate customers who are located in the same city and zipcode.
I have 2 questions regarding it:
1. Is the query syntax correct to find duplicate records by same city and zipcode, data is being returned but it just returns the same customer a few times?
2. I only need to do the GROUP BY clause for Fullname and City however it gives an error when the other columns are left out. The error is Address, State and Zip not being in the aggregate function or in the group by clause.
Adding all the remaining columns to the GROUP BY clause works.
Query is as below:

In my website their is a module in which I m retrieving the data from the student master table..
In my gridview their are 5 columns (Student Id,Student name,Roll no,and a checkbox column,Date Textbox column which is empty) in which the data is retrieved from student master table....
I m adding the date in the textbox which is out of the gridview and when i check the checkbox for each student the data is stored in another table in database with a status as present for the checked students and absent for the unchecked students...
What i want is dat when i check the student and i select the date for the student and the data is entered in new table after all this i wld not be allowed to make the attendance for the same student for the same date bt i wld be allowed to mark attendance for the same student for another date..
for example i check the checkbox for the student "Rohit" and entered the date 1/1/13 and rohit is stored with status present in the another table for date 1/1/13 and now he shld be disabled so dat i wld not be able to mark his attendance for the date 1/1/13 and prevent the duplication...Bt after dat i would be allowed to mark "Rohit's" attendance for the date 2/1/13...
means he should be disabled for the single date...

an attribute or some other setting. I am exporting the contents of a gridview to an excel spreadsheet. And for the most part it works great, with one minor annoyance, the export duplicates the entire gridview. In other words this is what I get:
Col1 | Col2 | Col3 | Etc | Col1 | Col2 | Col3 | Etc |
Code:
The GridView ASPX
<asp:GridView ID="GridViewList" runat="server"
BackColor="White" BorderColor="#E7E7FF" BorderStyle="Solid"
BorderWidth="1px" CellPadding="3" Width="100%" Font-Size="8pt"
