In the modified example, TestGetValue() returns a true or false to indicate a success or failure when parsing a number. If a true is returned, the parameter val will point to a valid number; otherwise, val should be not be used. Some of you might have caught that my use of Parse() and TryParse() is not very creative. The method TestGetValue() could have been reduced to a single line: bool TestGetValue(string buffer, out int val) { return int.TryParse(buffer, out val); }

Next, use Solver to forecast the average December yearly precipitation total for all cities. Assume a yearly precipitation combined average of 3 inches, with no monthly precipitation totals of less than 1 inch or more than 10 inches.

A UNIQUE field is allowed to accept NULL values, in which case it can only accept one NULL value. Indexes are automatically created on UNIQUE and PRIMARY KEY columns.

Default state is a useful technique to guard against exceptions that developers often ignore. When developers are writing their code, they will often return null when things don t work out. Using null is not a bad idea, but it adds unnecessary baggage. For example, consider the following code: class DefaultStateWrong { string[] Tokenize(string buffer) { return null; } public void IterateBuffers(string buffer) { string[] found = Tokenize(buffer); if (found != null) { for (int c1 = 0; c1 < found.Length; c1++) { Console.WriteLine("Found (" + found[c1] + ")"); } } } } The problem in this example is Tokenize(), which is a method used to convert the parameter buffer into a series of string tokens. Using safe exception coding, if the data could not be parsed, you could throw an exception, or you could return a null value indicating that the buffer could not be parsed. The caller code knows that there is the possibility of a null value when calling Tokenize(), and thus has an if block to check for the null value. The if block is defensive coding, but it also adds complexity because you need to verify for a null value. What if Tokenize() were a bit smarter and decided to return an empty array to indicate an empty result set The logic of this is not incorrect, because the caller expects either a result set with items or a result set with nothing in it. If a dramatically bad parsing error has occurred, the only recourse is to throw an exception. Here is the rewritten code:

Each column in a table has a particular data type. By looking at the previously shown Figure 4-8 with the Department table, it s clear that DepartmentID has a numeric data type, whereas Name and Description contain text. It s important to consider the many data types that SQL Server supports so that you can make correct decisions concerning how to create your tables. Table 4-1 isn t an exhaustive list of SQL Server data types, but it focuses on the main types you might come across in your project. Refer to SQL Server 2008 Books Online, which can be freely accessed and downloaded from http://msdn.microsoft.com/sql, for a more detailed list.

class DefaultStateRight { string[] Tokenize(string buffer) { return new string[0]; } public void IterateBuffers(string buffer) { string[] found = Tokenize(buffer); for (int c1 = 0; c1 < found.Length; c1++) { Console.WriteLine("Found (" + found[c1] + ")"); } } } In the rewritten code, Tokenize() returns an empty array that, when iterated using a for loop, will cause zero iterations. This is exception-safe code with improved readability. But what happens if Tokenize() does throw an exception With Tokenize() throwing an exception and the lack of a try/catch block in IterateBuffers(), it looks like IterateBuffers() is written incorrectly. However, IterateBuffers() is not written incorrectly, because Tokenize() will throw an exception only if something really problematic has occurred. A big problem is beyond the scope of the IterateBuffers() method, and thus needs to be handled at a higher level. Think of it as the situation where you have a criminal case and the local municipal court automatically delegates the case to the provincial or state level, because those courts are equipped to deal with such a case.

Note Table 4-1 was created with SQL Server 2008 in mind, but these data types exist in older versions of
