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
