根据以下语句写一个简短的实验总结：创建表空间需要create tablespace权限 对数据库操作需要grant dba to scott; 修改文件名需要先脱机手动进行修改； 无权限shutdown；

这段话主要介绍了在进行数据库操作时需要注意的注意事项。需要先授予操作用户相应的权限，使用命令`create tablespace`创建表空间，使用命令`grant dba to scott`授权给用户进行数据库操作。对于修改文件名的操作，需要先脱机，再手动进行修改。同时，需要注意的是，在没有相应权限的情况下，是无法进行数据库关闭的。因此，在进行数据库操作时应该非常小心谨慎。

这个 SQL 语句应该是可以在 Oracle 环境中执行的。它的作用是创建一个名为 cedar 的用户，并指定了该用户的默认表空间、临时表空间、角色和权限等信息。其中，该用户被授予了 DBA、RESOURCE、AQ_ADMINISTRATOR_ROLE、CONNECT、AQ_USER_ROLE 等角色，也被授予了 44 个系统权限（如 CREATE ANY DIRECTORY、EXECUTE ANY CLASS、CREATE TABLE 等）。此外，该用户还被授予了一些特殊的权限，如 EXECUTE ON sys.dbms_aq、EXECUTE ON sys.dbms_aqadm、EXECUTE ON sys.dbms_network_acl_admin 等。这些权限和角色的授予将使得该用户具有较高的系统权限，需要谨慎使用。

create user ZBGL identified by a1 default tablespace zbgl temporary tablespace temp; grant resource,connect,dba to ZBGL;

您的问题是如何创建一个用户并授予角色和权限。以下是创建用户ZBGL并授予角色和权限的SQL语句：

CREATE USER ZBGL IDENTIFIED BY a1 DEFAULT TABLESPACE zbgl TEMPORARY TABLESPACE temp;

GRANT RESOURCE, CONNECT, DBA TO ZBGL;

这将创建一个名为ZBGL的用户，并将其密码设置为a1。用户将使用zbgl表空间作为
