帮忙看下这个存储过程（在线等）

上面的存储过程在Sql   Server   2005中是正常的，在Sql   Server   2000中提示错误“第   39   行:   '% '   附近有语法错误。”
大家帮忙看看啊，谢谢

------解决方案--------------------
EXEC %%ExtendedPropertySet().AddValue()

Sql2000是不支持这样的用法的，CLR是Sql2005的新功能
------解决方案--------------------
在Sql Server 2005中也报错：
Msg 102, Level 15, State 1, Procedure sp_addextendedproperty, Line 39
Incorrect syntax near '% '.
