cannot create a synonym with same name as object

这个错误意味着你正在尝试创建一个同义词，但是同义词的名称与数据库中的其他对象（例如表、视图或存储过程）重复了。你需要更改同义词的名称，以确保它是唯一的。你可以通过以下方式检查同义词名称是否已在数据库中使用：

1. 使用 SQL Server Management Studio (SSMS) 或其他数据库管理工具，在数据库中浏览对象列表，检查是否存在同名对象。
2. 在 SQL Server Management Studio 的查询窗口中运行以下命令，以检查同义词是否已存在：

   SELECT * FROM sys.synonyms WHERE name = 'your_synonym_name'

如果查询返回结果，则表明同义词名称已存在。你需要选择一个不同的名称来创建同义词。

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 or replace synonym

create or replace synonym是一个SQL语句，用于创建或替换同义词。同义词是一个数据库对象，它允许用户在不知道实际对象名称的情况下访问该对象。使用create or replace synonym语句，用户可以创建一个新的同义词或替换现有的同义词。
