Web Forms :: How To Best Handle Unique Constraint During Data Insert Or Update

May 11, 2009

I have a table that have a field that I put in Unique constraint key set to yes. When the user click the insert button, I got the following error:

Violation of UNIQUE KEY constraint 'IX_emailGroups'. Cannot insert duplicate key in object 'dbo.emailGroups'.
The statement has been terminated.
Description:Exception Details: System.Data.SqlClient.SqlException: Violation of UNIQUE KEY constraint 'IX_emailGroups'. Cannot insert duplicate key in object 'dbo.emailGroups'.
The statement has been terminated.

What is the best way to handle unique errors as shown above? By the way, I'm using SqlDataSource control for my data insert. Should I handle this error in my C# code behind or through store procedure? Or, should I turn on AutoPostBack and then check the database if the recently entered data is unique or not by checking the database? I want an easy way to handle this.

SQL Server :: Dropping Primary Key On A Table?

Mar 29, 2011

I am working on a database with about twenty tables. In one of the tables "Customers" their is a column with

a primary key. Call it "CustomerNumber".

The problem is that we log customers from multiple vendors and so we might have the same customer number, but from different vendors. So really this would be a perfect situation where we could set up the primary key to be a composite key consisting of the Vendor and CustomerNumber combination.

The integrity of the database is not very well maintained because the Primary Key CustomerId is never used as a secondary key in any of the other tables.

So here is my question. Instead of making a primary composite key, can I just drop the primary key all together?

This is one of those questions I really hate to ask, because typically I would never lean tword this drastic of a measure to solve a problem. Because of other situations I can't discuss this might be the best alternative. So would it be okay to drop the primary key constraint all together?
