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?

Using vb.net/asp.net 2005 and sql server mgmt studio 2005.
I am querying sql server db and returning unique records, no duplicates when I return the records in sql server mgmt studio.
However when I bind the dataTable that I return it is showing multiple duplicates, meaning I see each record appear 8 times in the gridview, has anyone seen this or know what I'm doing wrong?
My code below:

removing duplicate rows from datatable or (dataset) by columnd ID (unique). Below function is working but I would like to edit/adjust the remaing (former) duplicate row's value, not the ID value btw.
Example:
ID name sport
-------------------------------
356 John Football
357 Johny Hockey
357 Johny Hockey
358 mike Soccer
should be:
ID name sport
--------------------------------------------------------------
356 John Football
357 Johny newFoo Hockey
358 mike Soccer
Public Function RemoveDuplicateRows(ByVal dTable As DataTable, ByVal colName As String) As DataTable
Dim hTable As New Hashtable()
Dim duplicateList As New ArrayList()
For Each drow__1 As DataRow In dTable.Rows
If hTable.Contains(drow__1(colName)) Then
duplicateList.Add(drow__1)
Else
hTable.Add(drow__1(colName), String.Empty)
End If
Next
For Each dRow__2 As DataRow In duplicateList
dTable.Rows.Remove(dRow__2)
Next
Return dTable
End Function

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 cant for the life of me see why. I have just also noticed that when i add the claim the first time it adds the duplicate entry, if i press the button again it only adds the entry once, if i refresh the page add the info again, 2 entries, click add again 1 entry?

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
7 Zach Modan
I need the query to filter.........
ID FirstName LastName
1 Zach H Hoffman
2 Zach Hoffman
3 Troy Hoffman
6 Jony Hoffman H
7 Zach Modan
I hope this example will give you clear idea..... I need SQL Query to perform this

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:

I have 2 divs with 2 nested divs in them. Let's say div1 contains div11 and div12 and div2 can also contain div11 and div12. I know that this is not normally allowed but I am using jTemplates and they do allow you to print the div11 and div12 twice or more on the same page. The HTML looks like this:
<DIV1>
<DIV11>Some text</DIV11>
<DIV12>Some text</DIV12>
</DIV1>
<DIV2>
<DIV11>Some text</DIV11>
<DIV12>Some text</DIV12>
</DIV2>
How do I ensure that I only have one div with the unique ID loaded on the page, so I don't get in any duplicate DIVs. The result should look like this:
<DIV1>
<DIV11>Some text</DIV11>
<DIV12>Some text</DIV12>
</DIV1>
<DIV2>
Some other text
</DIV2>
Is there any way to check for a duplicate ID in either jQuery/javascript language and remove all but one using each or some other method?

When I run my above code shows error as follows Column 'Remarks' does not belong to underlying table 'Table1'. The above error shows in the below function as follows :
DataTable dt = new DataTable();
dt = (DataTable)ViewState["Remarks"];
dt = dt.DefaultView.ToTable(true, "Dropdown", "Remarks");

Duplicate Data in Gridview and Updating textbox in DetailsView

I'm getting duplicated rows of data showing up in my GridViews. I have two GridViews, each showing different data. I'm using SQL queries to retrieve the data from 2 database tables (1 query pulls from one table and the other query pulls from a second table, but references the first table in the WHERE clause). The GridViews were not duplicating data until after I added the Data Binding code to each GridView event handler and the button click event handler (outside of the GridView). I double checked my SQL queries by running them in TOAD and did not get any duplicated rows. So the issue is not with the SQL queries. It appears to be the GridViews causing it, or the Data Binding, or combination of those two, but I'm not sure what it is.Has anyone heard of or seen this? If needed, I can post my VB code and GridView code.
