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 have 3 drop down lists on a form that collects data from a visitor.
Each DDL shows a list of Music Genre and the User can make up to 3 choices ( 1 selection from each DDL)
I want to loop through the DDL´s and Insert the GenreId (int) and UserId (Guid) into a Junction Table called
UserGenre which has UserId and GenreId as Primary Keys.
In C sharp - How can I loop through and get each DDL selected value (If chosen) from the form and insert to table?

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 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:

lblMsg.Text = "Records Existed"

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?

Conseptually what I'm doing is simple, and technically it may even be simple, but I'm still rusty. Here's what I'm trying to do:
I have a webform that allows the user to enter a new record, and in there I have also included a couple FileUpload controls. Upon clicking the "Save" button, I'm saving the details entered into one table (ITEMS), and also inserting the FileUpload details (path, id, upload_user) into another table ATTACHMNTS). Because one ITEM can have many attachments, I needed to split the tables up. So on save, I need to save the ITEM, save the ATTACHMENT, and then also put the ITEM_ID in the ATTACHMENT table. I'm second guessing myself because I think all I'd have to do is after I do the ITEM insert, do a SELECT MAX on the ITEM table and hold the newest (MAX) id in a variable and then use it in the ATTACHMENTS update. I'm not 100% on this because there IS a chance that someone else could save a few milliseconds later and I'll link the wrong ITEM. See my delima?

Suppose we have a website with 10,000 viewers each second. And we want to insert the viewer's information to the SQL database. So we must insert 10,000 records to the SQL each second. And it may take long time to do.
My question is: How can we decrease this process.

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...
