思路是:Grants permissions on a securable to a principal.
The general concept is to GRANT <some permission> ON <some object> TO <some user, login, or group>.
授予权限子句分为三部分:Permission,Securable 和 principal,用一句话来解释这三个concept:授予 Principal 操作 Securable 的 Permission。
Principal是被授予权限的实体,Securable是table,view等对象,是Principal操作的对象;有时Principal也会作为Securable,被Principal操纵。
示例步骤
Step1,Create Login
Step2,Create user,建立User 和 Login之间的关联,通过SID来关联。
Step3,Create Role
Step4,授予Role的权限
Step5,将user 增加为role的成员,使User 具有权限
USE db_study; GO --Create login CREATE LOGIN login1 WITH PASSWORD = ‘123‘ ,DEFAULT_DATABASE=db_study ,CHECK_EXPIRATION=off ,CHECK_POLICY=off; go --create user CREATE USER user1 FOR LOGIN login1 with default_schema=dbo; GO --create role create role role1 AUTHORIZATION user1; GO --create schema create schema schema1 AUTHORIZATION user1; go --create object create table schema1.table1 (id int,name varchar(10)) create table schema1.table2 (id int,name varchar(10)) --grant permission on schema to role grant select,execute on schema::schema1 to role1; --grant permission on object to role grant select ,insert on object::schema1.table2 to role1; --add member alter role role1 add member user1; go
