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

DataSource Controls :: Import Excel Sheet To Sql Server Existing Table?
I'm trying to import a excel file, one sheet, to an sql server. I already have the table created, so i just wanted to fill the columns.
The problem is when i import the excel file, it always creates me a new table, when all i wanted, was just fill the existing table with the data of the file.
The table in the database has just one more column then the the excel file. The extra column is the ID (counter - identity).
I couldn't make the counter in the excel file, because this table will receive lots of excel files, so the counter wouldn't be right.
I already tried using "Integration Services Project", but it doens't work. I followed every steps of a web page i found, but when i run the project it still gives an error [URL]
PS- i know that i can always copy the data from the table created to the desired table, but i don't want to do that.

DataSource Controls :: Way O Insert Statement Conflicted With Column Foriegn Key Constraint
I have a stored procedure which i pass a number of parameters into. One of these parameters is staffNo (only passed this in because i couldn't execute the query without it). The thing is this field can be Null, but when trying to pass null into it it comes up with an Foreign Key conflict. staffNo is a foreign key within the table i'm inserting the data into.This is the error i get:"INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'PropStaffFK'. The conflict occurred in database 'DewMountain', table 'TblStaff', column 'staffNo'. The statement has been terminated. The 'PropertyAdvert' procedure attempted
to return a status of NULL, which is not allowed. A status of 0 will be returned instead. "
