本文详细解析了在Oracle数据库中遇到的ALTER TABLE|INDEX RENAME操作可能与其他操作结合使用的错误（ORA-14047）。通过查询知识库，发现原因在于在实际表重命名和指定目标模式名时进行的操作组合不当。文章提供了实例演示，并给出避免此错误的方法。

查询mos，得到如下文章：ORA-14047: ALTER TABLE | INDEX RENAME May Not Be Combined With Other Operations (文档 ID 400398.1)
在该文章中，说明了报错的原因：

The combination of actions appear to be:
1.the actual table rename
2.specifiying the schema name of the target

也就是说，不要带目标表的schema

值得注意的是，即使是在相同的一个schema下，目标表带有相同的schema名称，也是不允许的，如下：

SQL> show user
USER is "LC0029999"
SQL> alter table lc0029999.t1 rename to lc0029999.tt1; 
alter table lc0029999.t1 rename to lc0029999.tt1
                                            *
ERROR at line 1:
ORA-14047: ALTER TABLE|INDEX RENAME may not be combined with other operations

SQL>

但是源表可以带schema信息，如下：

SQL>  alter table lc0029999.t11 rename to tt1;

Table altered.
