Aspx page to get rid of the second record. 7. Click the Insert button to insert the record. This time, the data context called the stored procedure to add the record, instead of the dynamic SQL that was generated before. ReturnValue)); } The first method takes an ENTUserAccount object as a parameter and calls the second method, passing the properties as parameters. The second method takes a parameter for each parameter of the stored procedure. It then calls the ExecuteMethodCall of the DataContext object.
The Select method, with no parameters, returns a list of these objects; and the Select method, with the id parameter, returns a single instance of this type of object. I didn’t add abstract methods for the Insert and Update methods because they will be different for each class (because I use the pattern of passing in each field, rather than the object, to insert or update a method). I use this pattern so that if I add a field, I can change the signature of the Insert and Update methods and let the compiler tell me where to fix the calling code.
Another disadvantage of the DataReader is that it is only a one-way communication vehicle for passing data back to the caller. You cannot use a DataReader to pass data into the DAL to update the database. By definition, a DataReader is read-only, so if you choose the DataReader as the vehicle for passing data back to the caller, you need a different vehicle for passing data into the DAL. Another disadvantage to the DataReader is that it is not strongly typed and each field must be cast to its correct type by the user of the DataReader.
