However, primary key information is not included in the implicitly created schema unless the Data Adapter.
When the Sql Data Adapter fills a Data Set, it creates the necessary tables and columns for the returned data if they do not already exist.
You can use an output parameter of a stored procedure that performs the insert action, or you can use the Sql Data Adapter object's Row Updated method.
The simplest way to get the value of an IDENTITY column is to set up the identity value as an output parameter of a stored procedure and use the Sql Data Adapter to map that value back to the column in the Data Set.
However, in some cases, the application or the user needs to know the IDENTITY column's assigned value as soon as you add the row to the database.Listing 1, page 20, shows a stored procedure that inserts an employee record into the Northwind database's Employees table and returns the identity field of Employee ID as an output parameter.The most important point to notice about this stored procedure is the use of the SCOPE_IDENTITY() function, which retrieves the identity value SQL Server assigns, then sets that value into the @Identity variable that the stored procedure returns.Row Updating, Address Of On Row Updating Remove Handler r Adapter.
