When you deal with an outside resource such as a database, you need to protect your code with a basic amount of error-handling logic. Even if you ve avoided every possible coding mistake, you still need to defend against factors outside your control for example, if the database server isn t running or the network connection is broken. You can count on the SqlDataSource to properly release any resources (such as connections) if an error occurs. However, the underlying exception won t be handled. Instead, it will bubble up to the page and derail your processing. As with any other unhandled exception, the

dependence, which means the table isn t in 3NF. The PlayerUrl column should be moved to the Player table for the whole database to be in 3NF. Normalizing a database will make it faster to sort and search through by reducing the chance of redundant data in the database. In particular, the database will need fewer indexes, which will improve the performance of INSERT, UPDATE, and DELETE queries. However, normalization can increase the complexity of joins required to retrieve the data. This, in some cases, may hinder performance. Sometimes, databases are denormalized to reduce the complexity of joins and to get quicker query response times (one of the reasons why fourth and fifth normal forms aren t often used). As always, you need to strike a balance between flexibility and speed. This is just another juggling act you ll encounter as you implement the Web site.

The way we are going to do this is by writing values to the web server environment in the Apache configuration. Using the Apache SetEnv direct, we are going to write a value that specifies the name of the configuration section to use, as well as the name of the settings file to use. We then modify the index.php bootstrap to read and use these values. These values don t have to be specified: if they are not included in the configuration, we will use a default settings file of settings.ini and a default configuration section of production.

user will receive a cryptic error message or an error page. This design is unavoidable if the SqlDataSource suppressed exceptions, it could hide potential problems and make debugging extremely difficult. However, it s a good idea to handle the problem in your web page and show a more suitable error message. To do this, you need to handle the data source event that occurs immediately after the error. If you re performing a query, that s the Selected event. If you re performing an update, a delete, or an insert operation, you would handle the Updated, Deleted, or Inserted event instead. (If you don t want to offer customized error messages, you could handle all these events with the same event handler.) In the event handler, you can access the exception object through the SqlDataSourceStatusEventArgs.Exception property. If you want to prevent the error from spreading any further, simply set the SqlDataSourceStatusEventArgs.ExceptionHandled property to true. Then, make sure you show an appropriate error message on your web page to inform the user that the command was not completed. Here s an example: protected void sourceProducts_Selected(object sender, SqlDataSourceStatusEventArgs e) { if (e.Exception != null) { lblError.Text = "An exception occurred performing the query."; // Consider the error handled. e.ExceptionHandled = true; } }
