CREATE PROCEDURE AssignProductToCategory (@ProductID int, @CategoryID int) AS INSERT INTO ProductCategory (ProductID, CategoryID) VALUES (@ProductID, @CategoryID) Note that you don t do any verification here. If an error occurs (because the entered ProductID is not associated with any product or the ProductID, CategoryID pair already exists in the ProductCategory table), it is trapped at the upper levels, and the administrator is notified. Still, since we talked about the error-handling techniques, it s worth noting that you can make the stored procedure smart enough to do some validation before attempting to add the (ProductID, CategorID) pair to ProductCategory table. Following is a bulletproof version of the stored procedure that inserts the new record into ProductCategory only if the received ProductID and CategoryID values are valid and the pair doesn t already exist in the database: CREATE PROCEDURE AssignProductToCategory (@ProductID int, @CategoryID int) AS IF EXISTS (SELECT Name FROM Product WHERE ProductID = @ProductID) AND EXISTS (SELECT Name FROM Category WHERE CategoryID = @CategoryID) AND NOT EXISTS (SELECT * FROM ProductCategory WHERE CategoryID = @CategoryID AND ProductID = @ProductID) INSERT INTO ProductCategory (ProductID, CategoryID) VALUES (@ProductID, @CategoryID) We won t use this version in practice because we prefer to be notified in case an illegal association is attempted. MoveProductToCategory MoveProductToCategory is the stored procedure that moves a product from one category to another: CREATE PROCEDURE MoveProductToCategory (@ProductID int, @OldCategoryID int, @NewCategoryID int) AS UPDATE ProductCategory SET CategoryID = @NewCategoryID WHERE CategoryID = @OldCategoryID AND ProductID = @ProductID

CreateCommand creates a DbCommand object, sets some standard properties to it, and returns the configured object If you preferred to use a database-specific command object, such as SqlCommand, the code would have been a bit simpler, but in this case we prefer to have database-independent access code, as explained earlier in this chapter The CreateCommand method uses the steps presented earlier in this chapter to create a command object specific to the database implementation you re working with, wrap that instance into a generic DbCommand reference, and return this reference This way, external classes will be able to call CreateCommand to get an already configured with a prepared connection DbCommand object ExecuteSelectCommand is essentially a wrapper for DbCommand s ExecuteReader method, except it returns the results as a DataTable instead of a DataReader Using the DataTable ensures that the database connection is kept open as short as possible.

We can then subclass AdapterWrapper to create RateableWrapper, overriding the default getView() but otherwise allowing the delegated ListAdapter to do the real work:

In this method, you implement an errorhandling technique that guarantees that in case of an exception, the administrator is informed by email (if the application is configured to do so), the database connection is properly closed and the error is rethrown We decided to let the error propagate because this class is at too low a level to know how to properly handle the errors At this point, we re only interested in keeping the database safe (by closing the connection) and reporting any eventual error The best example of how a client class can use GenericDataAccess to work with the BalloonShop database is the GetDepartments method in the CatalogAccess class All the classes you ve added are static classes, which are composed exclusively of static members.
