    在SQL Server 2008中，某数据库用户User在此数据库中具有对于表数据的查询和更改权限。现要收回User对于T表的数据更改权，下述是实现该功能的语句，请补全该语句。【8】UPDATE ON T FROM User。


    正确答案：
    REVOKE【解析】对数据的访问是通过SQL Server 2008的权限层次结构进行管理的。可以通过GRANT、DENY和REVOKE语句来管理这个权限层次结构。三种语句的作用分别为：①GRANT：允许一个数据库用户或角色执行所授权限指定的操作；②DENY：拒绝一个数据库用户或角色的特定权限，并且阻止它们从其他角色中继承这个权限；③REVOKE：收回已经授予的权限。
