Sql Server CLR Functions

Question

While writing a CLR function Sql Server can we use namespaces ?

namespace SomeName1.SomeName2
{
   public static class SomeClass
   {
       [SqlFunction]
       public static SqlString SomeMethod(SqlString input)
       {
          // ....
       }
   }
}

If so, then how do we call this function from SqlServer. In other words how do we call CLR functions from SQL Server with namespaces?

Answer 1

Yes, you absolutely can:

CREATE FUNCTION SomeMethod(@input VarChar(200))
RETURNS VarChar(200) WITH EXECUTE AS CALLER AS

EXTERNAL NAME [SomeName1.SomeName2].[SomeName1.SomeName2.SomeClass.SomeMethod]

Where [SomeName1.SomeName2] in the first part is the assembly as named in SQL Server, and the rest ([SomeName1.SomeName2.SomeClass.SomeMethod]) is the fully qualified function name, including the namespace.

Incidentally, if you deploy from Visual Studio it handles a lot of this for you.
