给SQLServer数据库添加表说明和表字段说明

1. 给表添加说明:

exec sp_addextendedproperty @name = N'Description_A' 
  ,@value = N'雇员表' 
  ,@level0type='SCHEMA' 
  ,@level0name = dbo --結構名 
  ,@level1type='table' 
  ,@level1name='Employee' --表名 
--獲取添加的表描述信息 
select * from fn_listextendedproperty(null,'SCHEMA','dbo','table','Employee',null,null)
GO

2. 给表的字段添加说明:

CREATE TABLE [dbo].[Answers](
 [RequestID] [int] NULL,
 [CustomerID] [int] NULL,
 [CustomerCompany] [varchar](100) COLLATE Chinese_PRC_CI_AS NULL,
 [AnswerContent] [varchar](5000) COLLATE Chinese_PRC_CI_AS NULL,
 [AddTime] [smalldatetime] NULL
) ON [PRIMARY]
