文档解释
ORA-25960: join index cannot be based on a temporary table
Cause: An attempt to create a join index was made, which failed because one of the tables was temporary.
Action: Ensure no underlying tables are temporary.
ORA-25960错误是指Oracle系统不允许基于临时表创建连接索引。ORA-25960错误的官方解释如下：
ORA-25960: join index cannot be based on a temporary table
Cause: The CREATE JOIN INDEX statement specified a table with the TEMPORARY keyword. A join index cannot be created based on a temporary table.
Action: Remove the TEMPORARY keyword from the table name in the CREATE JOIN INDEX statement, or consider a different index creation option.
此ORA-25960错误最常见的案例就是在开发人员或者管理员尝试创建一个基于临时表的连接索引中容易出现这个错误。
一般处理方法及步骤
1. 仔细阅读ORA-25960错误的提示信息，了解错误究竟是什么原因导致的。
2. 分析SQL脚本，了解是否在涉及到基于临时表的连接索引的操作中。
3. 如果是在进行基于临时表的连接索引的操作，则检查是否添加了TEMPORARY关键字，并尝试删除TEMPORARY关键字，重新运行sql脚本。
4. 如果不是基于临时表的连接索引，则分析其他条件，尝试修改SQL脚本，重新运行。
