sqlserver创建login、user并授予相应数据库的权限

create login login1 with password='111111' --创建一个login，用于登录

go

use [BookDB] --在数据库[BookDB]上创建用户user1，拥有下面三个权限

go

create user user1 for login login1 with default_schema=dbo

go

exec sp_addrolemember 'db_ddladmin','user1'

exec sp_addrolemember 'db_datareader','user1'

exec sp_addrolemember 'db_datawriter','user1'

go

use [BookLibrary] --在数据库[BookLibrary]上创建用户user2，赋予下面三个权限

go

create user user2 for login login1 with default_schema=dbo

go

exec sp_addrolemember 'db_ddladmin','user2'

exec sp_addrolemember 'db_datareader','user2'

exec sp_addrolemember 'db_datawriter','user2'

go

use [BookLibrary] --在数据库[BookLibrary]上创建用户user2，收回下面三个权限

go

exec sp_droprolemember 'db_ddladmin','user2'

exec sp_droprolemember 'db_datareader','user2'

exec sp_droprolemember 'db_datawriter','user2'

go

--上面复权的另一种写法

USE [BookLibrary]

GO

ALTER ROLE [db_ddladmin] add MEMBER [user2]

GO

ALTER ROLE [db_datareader] add MEMBER [user2]

GO

ALTER ROLE db_datawriter add MEMBER [user2]

--上面收权的另一种写法

USE [BookLibrary]

GO

ALTER ROLE [db_ddladmin] DROP MEMBER [user2]

GO

ALTER ROLE [db_datareader] DROP MEMBER [user2]

GO

ALTER ROLE db_datawriter DROP MEMBER [user2]
