MVC :: Validating Primary Key Which Is Identity?
Sep 14, 2010I am following this tutorial : [URL]
I am where you "Create" an entry in the table, i have deleted the Id field, as Id is my primary key, and Is Identity = Yes, Identity Increment = 1, Identity Seed = 1.
When i hit the create button, the Id value is being validated, giving an invalid error. If i add the Id column back to the page, and fill in any number and click create, the entry is added to the database, with the Id value incremented (the typed in value does not matter). I believe this must have to do with the Movies.Designer.cs... but not sure how to fix it. Id should not be validated as it auto-incraments, but the model is looking for a Id value..
Retrieve Identity Value From Inserted Record's Primary Key?
Mar 14, 2011i cannot retrieve the new identity value from an inserted record(via DataAdapter.Update) in my DataRow.
I'm using a strong typed Dataset as DAL. The table i want to update is joinded with other tables in the SelectCommand, hence the designer cannot automatically generate the insert-/update-/delete-commands and also it cannot "Refresh the DataTable" automatically. [URL]
I've tried to set AutoIncrement=true/false on the primary-key's DataColumn but the result is the same: last MAX-ID+1 instead of the actual ID the database generated(SQL-Server 2005 EP; pk datatype:int, Is identity:yes, Identity Increment:1).
This will be the wrong value f.e if another instance of the application inserted a record that the first instance yet not knows and therefore generates an ID that already exists.
To retrieve the new identity from db i've appended following to my insert-command's CommandText:
;SELECT CAST (SCOPE_IDENTITY() AS int) AS newIdRMA
Also i've tried to add an Output-Parameter to it's parameter-collection:
This is part of my code that updates the database and sets the new ID(that doesn't work):

View 5 RepliesSQL Server :: Dropping Primary Key On A Table?
Mar 29, 2011I 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?

SQL Server :: Show Primary Key Value In Web Form?
Nov 12, 2010I was wondering has anyone ever had a requirement to show the Primary Field Id value in a form when it Loads? I notice that in SQL Server there is no visible value assigned to the Primary column until you enter the data in all the fields and then move to the next row. Is this value stored somewhere internally so that I can show it on the webform to the user?
