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?

I have a database table that stores a list of friends. The table can store many friends and there can be duplicates, for example - John is James' and davids' friend. John will be in the table twice but will be linked to the others via another data-member. What i dont want is james to be down as johns friend twice in the table. I'm doing a small social network and this is possible by james accepting john as his friend twice. Is there anything to check if there are 2 columns identical?

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:

On inserting record, I want to check that for example if a user enters a telephone number for any record is already in the database then it should validate that the number already exists in table and you cannot enter a duplicate value.
Then if user will provide some other telephone number then he allows to insert record.
For insertion of record I used ObjectdataSource.
User will enter telephone number in a simple textbox.
I may want to inform that I am working in asp.net2.0 and also not allowed to use any third party control or ajaxtoolkit.

I have a formview and inside it there are two textboxes taking integer as input.I put a condition that if both textboxes are empty then user should be notified that "Please put value in any one of the textbox".It is working very fine.From database side DBA checked that if user input any integer value in any one of the two textboxes and if it is already found in database then there is no insertion.The problem is that everything is working fine and i checked in the database that the record is also not inerting due to duplicate check but user is getting message that "Record inserted successfully."How to stop this message and how to notify user that you have entered duplicate value and transaction should also not been done. Means all inputs should be there rather than clearing textboxes that could be done when "Record Inserted."

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:

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...
