grant select any table

grant select any table 是一种授权语句，用于授予用户在任何表上执行 SELECT 操作的权限。这意味着用户可以查询数据库中的任何表，而不仅仅是自己拥有的表。这种授权通常只授予给具有高级权限的用户，如数据库管理员。

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。

根据提供的引用内容，可以得知Oracle数据库在授予数据库级别权限时不支持通配符。也就是说，当你授予数据库级别的权限时，你必须指定一个具体的数据库名称，而不能使用通配符来匹配多个数据库。

例如，在以下语句中，我们试图授予用户“testuser”对所有以“mydb_”开头的数据库的“connect”权限：

GRANT CONNECT TO testuser@'%' IDENTIFIED BY 'password' WITH ADMIN OPTION;
GRANT CREATE SESSION TO testuser@'%' IDENTIFIED BY 'password' WITH ADMIN OPTION;
GRANT SELECT ANY TABLE TO testuser@'%' IDENTIFIED BY 'password' WITH ADMIN OPTION;
GRANT INSERT ANY TABLE TO testuser@'%' IDENTIFIED BY 'password' WITH ADMIN OPTION;
GRANT UPDATE ANY TABLE TO testuser@'%' IDENTIFIED BY 'password' WITH ADMIN OPTION;
GRANT DELETE ANY TABLE TO testuser@'%' IDENTIFIED BY 'password' WITH ADMIN OPTION;

然而，这样的语句是不被支持的，你必须指定一个具体的数据库名称，例如“mydb_test”。
