获取、增加、修改、删除sqlserver字段描述及快速查看表字段与描述

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 

--表描述
