If the insert fails, the problem will be reported to the user in a rather unfriendly way (see Figure 13-13). This is typically the result of not specifying valid values. In a more polished application, you would use validators (as shown in 8) and provide more useful error messages. If the insert operation is successful, the page is updated with the new author list.

Summary

The previous example performed its database work using a dynamically pasted-together SQL string. This off-the-cuff approach is great for quickly coding database logic, and it s easy to understand. However, it has two potentially serious drawbacks: Users may accidentally enter characters that will affect your SQL statement. For example, if a value contains an apostrophe ( ), the pasted-together SQL string will no longer be valid. Users might deliberately enter characters that will affect your SQL statement. Examples include using the single apostrophe to close a value prematurely and then following the value with additional SQL code.

At this point, any client that binds to our service will be able to access the service object itself and call methods on it. We will go into this in greater detail in the next chapter.

The second of these is known as SQL injection attack, and it facilitates an amazingly wide range of exploits. Crafty users can use SQL injection attacks to do anything from returning additional results (such as the orders placed by other customers) or even executing additional SQL statements (such as deleting every record in another table in the same database). In fact, SQL Server includes a special system stored procedure that allows users to execute arbitrary programs on the computer, so this vulnerability can be extremely serious. You could address these problems by carefully validating the supplied input and checking for dangerous characters such as apostrophes. One approach is to sanitize your input by doubling all apostrophes in the user input (in other words, replace ' with " ). Here s an example:

Dim authorID As String = txtID.Text.Replace("'", "''")
