SqlServer查询表名的备注（查询表名描述 MS_Description）

查询表名描述 MS_Description

  SELECT tbs.name 表名,ds.value 描述       
  FROM sys.extended_properties ds  
  LEFT JOIN sysobjects tbs ON ds.major_id=tbs.id  
  WHERE  ds.minor_id=0 and  
  tbs.name='ScheduleRecords';--表名

添加表的描述

EXECUTE sp_addextendedproperty N'MS_Description', N'菜单表', N'user', N'dbo', N'table', N'Menus', NULL, NULL;

更新表的描述

EXECUTE sp_updateextendedproperty N'MS_Description', N'菜单表', N'user', N'dbo', N'table', N'Menus', NULL, NULL;

查询表的外键

  SELECT tbs.name 表名,ds.value 描述      
  FROM sys.extended_properties ds  
  LEFT JOIN sysobjects tbs ON ds.major_id=tbs.id  
  WHERE  ds.minor_id=0 and   
  tbs.name='ScheduleRecords';--表名
  WHERE OBJECT_NAME(sysobjects.parent_obj)='Table Name'
