The outer CASE expression rst uses a pivoting technique to check whether a 0 value appears in the group, in which case it returns a 0 as the result. The ELSE clause invokes another CASE expression, which also uses a pivoting technique to count the number of negative values in the group. If that number is even, it produces a +1; if it s odd, it produces a 1. The purpose of this calculation is to determine the numerical sign of the result. The sign ( 1 or +1) is then multiplied by the product of the absolute values of the numbers in the group to give the desired product. Note that NULLIF is used here to substitute zeros with NULLs. You might expect this part of the expression not to be evaluated at all if a zero is found. But remember that the optimizer can consider many different physical plans to execute your query. As a result, you can t be certain of the actual order in which parts of an expression will be evaluated. By substituting zeros with NULLs, you ensure that you ll never get a domain error if the LOG10 function ends up being invoked with a zero as an input. This use of NULLIF, together with the use of ABS, allows this solution to accommodate inputs of any sign (negative, zero, and positive).

Attributes are a .NET feature with no direct Java equivalent. For a Java developer new to C#, attributes may well be one of the hardest language features to appreciate. However, knowledge of attributes is essential to use the .NET Framework for anything but the most trivial programs. Attributes are a generic mechanism for associating declarative information (metadata) with program elements. This metadata is contained in the compiled assembly, allowing programs to retrieve it through reflection at run time. Other programs, particularly the common language runtime (CLR), use this information to determine how they should interact with and manage program elements. There are many predefined attributes in the .NET class libraries, but the power and flexibility of attributes stem from the fact that they are classes. Custom attributes can be created by deriving a class from the abstract base class System.Attribute. This provides a metadata mechanism that is extensible beyond the scope of the default .NET class libraries. This section looks first at how to assign existing attributes to elements of code and then at how to define custom attributes. We don't discuss all the attributes included in the .NET class libraries; these will be discussed throughout the rest of the book in sections relevant to their purpose.

You could also use a pure mathematical approach to handle zeros and negative values using the following query:

SELECT groupid, CAST(ROUND(EXP(SUM(LOG(ABS(NULLIF(val,0)))))* (1-SUM(1-SIGN(val))%4)*(1-SUM(1-SQUARE(SIGN(val)))),0) AS INT) AS product FROM dbo.Groups GROUP BY groupid;

The mechanisms used to access attribute metadata at run time are covered in 12, "Reflection."
