This solution might seem awkward at first glance . You create a separate stored procedure with a single static query for each possible combination of inputs . Then, GetSortedShippers can act as a redirector . Simply use a series of IF/ELSE IF statements to check for each possible combination of inputs, and you explicitly invoke the appropriate stored procedure for each . Sure, it is a bit long and requires more maintenance than the previous solution, but it uses static queries that generate optimal plans . Note that each query gets its own plan and can reuse a previously cached plan for the same query . To test the procedure, run the following code:

CLR Stored Procedures
SQL Server 2008 allows you to develop CLR stored procedures (as well as other routines) using a .NET language of your choice . The previous chapter provided background about CLR routines, gave advice on when to develop CLR routines versus T-SQL ones, and described the technicalities of how to develop CLR routines . Remember to read Appendix A for instructions on developing, building, deploying, and testing your .NET code . Here I d just like to give a couple of examples of CLR stored procedures that apply functionality outside the reach of T-SQL code . The first example is a CLR procedure called GetEnvInfo . This stored procedure collects information from environment variables and returns it in table format . The environment variables that this procedure will return include: Machine Name, Processors, OS Version, CLR Version . Note that to collect information from environment variables, the assembly needs external access to operating system resources . By default, assemblies are created (using the CREATE ASSEMBLY command) with the most restrictive PERMISSION_SET option, SAFE, which means that they re limited to accessing database resources only . This is the recommended option to obtain maximum security and stability . The permission set options EXTERNAL_ACCESS and UNSAFE (specified in the CREATE ASSEMBLY or ALTER ASSEMBLY commands, or in the Project | Properties dialog box in Visual Studio under the Database tab) allow external access to system resources such as files, the network, environment variables, or the registry . To allow EXTERNAL_ACCESS and UNSAFE assemblies to run, you also need to set the database option TRUSTWORTHY to ON . Allowing EXTERNAL_ACCESS or UNSAFE assemblies to run represents a security risk and should be avoided . I will describe a safer alternative shortly, but first I ll demonstrate this option . To set the TRUSTWORTHY option of the CLRUtilities database to ON and to change the permission set of the CLRUtilities assembly to EXTERNAL_ACCESS, run the following code:
USE CLRUtilities; -- Database option TRUSTWORTHY needs to be ON for EXTERNAL_ACCESS ALTER DATABASE CLRUtilities SET TRUSTWORTHY ON; -- Alter assembly with PERMISSION_SET = EXTERNAL_ACCESS ALTER ASSEMBLY CLRUtilities WITH PERMISSION_SET = EXTERNAL_ACCESS;
