Managing CLR Integration Assemblies

업데이트: 2005년 12월 5일

Managed code is compiled and then deployed in units called an assembly. An assembly is packaged as a DLL or executable (.exe) file. While an executable file can run on its own, a DLL must be hosted in an existing application. Managed DLL assemblies can be loaded into and hosted by Microsoft SQL Server 2005. SQL Server requires you to register the assembly in a SQL Server database using the CREATE ASSEMBLY statement, before it can be loaded in the process and used. Assemblies can also be updated from a more recent version using the ALTER ASSEMBLY statement, or removed from SQL Server using the DROP ASSEMBLY statement.

Assembly information is stored in the sys.assembly_files table in the database where the assembly has been installed. The sys.assembly_files table contains the following columns.

Column Description

assembly_id

The identifier defined for the assembly. This number is assigned to all objects relating to the same assembly.

name

The name of the object.

file_id

A number identifying each object, with the first object associated with a given assembly_id being given the value of 1. If multiple objects are associated with the same assembly_id, then each subsequent file_id value is incremented by 1.

content

The hexadecimal representation of the assembly or file.

The following table lists the topics in this section.
