先看添加与删除字段描述

EXEC sys.sp_addextendedproperty @name = N'MS_Description',
--添加Type字段说明
@value = N'屏蔽类型对应值(类型对应Id)',
@level0type = N'SCHEMA',
@level0name = N'dbo',
@level1type = N'TABLE',
@level1name = N'ForbiddenType',
@level2type = N'COLUMN',
@level2name = N'TypeId' --删除表中列Type的描述属性：
EXEC sp_dropextendedproperty 'MS_Description',
'SCHEMA',
dbo,
'TABLE',
'ForbiddenType',
'COLUMN',
TYPE

看下面的实例：

--创建表及描述信息 create table 表(a1 varchar(),a2 char()) --为表添加描述信息
EXECUTE sp_addextendedproperty N'MS_Description', '人员信息表', N'user', N'dbo', N'table', N'表', NULL, NULL

EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'生成记录表' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'CrabRequisition'
GO

--为字段a1添加描述信息
EXECUTE sp_addextendedproperty N'MS_Description', '姓名', N'user', N'dbo', N'table', N'表', N'column', N'a1'EXECUTE sp_addextendedproperty N'MS_Description', '测试', N'user', N'dbo', N'table', N'HR_Employees', N'column', N'test' --为字段a2添加描述信息
EXECUTE sp_addextendedproperty N'MS_Description', '性别', N'user', N'dbo', N'table', N'表', N'column', N'a2'
--更新表中列a1的描述属性：
EXEC sp_updateextendedproperty 'MS_Description','字段1','user',dbo,'table','表','column',a1 --删除表中列a1的描述属性：
EXEC sp_dropextendedproperty 'MS_Description','user',dbo,'table','表','column',a1
