Adding new assembly and functions

1. Check if there is any previous assembly exists. If there is any, then remove it.

SELECT
        SCHEMA_NAME(O.schema_id) AS [Schema], O.name,
        A.name AS assembly_name, AM.assembly_class,
        AM.assembly_method,
        A.permission_set_desc,
        O.[type_desc]
FROM
        sys.assembly_modules AM
        INNER JOIN sys.assemblies A ON A.assembly_id = AM.assembly_id
        INNER JOIN sys.objects O ON O.object_id = AM.object_id
ORDER BY
        A.name, AM.assembly_class

2. Copy dll file to server (eg: F:\Parvez\Msdn.SqlRegex.dll')

3. Create assembly in database.

                    create assembly "Msdn.SqlRegex" from 'F:\Parvez\Msdn.SqlRegex.dll'

4. Create sql object using that assembly.

5. Check created objects

   SELECT

        SCHEMA_NAME(O.schema_id) AS [Schema], O.name,
        A.name AS assembly_name, AM.assembly_class,
        AM.assembly_method,
        A.permission_set_desc,

        INNER JOIN sys.objects O ON O.object_id = AM.object_id
ORDER BY
        A.name, AM.assembly_class
