文档解释
ORA-14291: cannot EXCHANGE a composite partition with a non-partitioned table
Cause: A composite partition can only be exchanged with a partitioned table.
Action: Ensure that the table being exchanged is partitioned or that that the partition being exchanged is non-composite.
ORA-14291：不能用非分区表交换复合分区
官方解释
Oracle 数据库报告 ORA-14291 错误，因为不能使用 ALTER TABLE … EXCHANGE PARTITION 子句将复合分区交换给非分区表。
常见案例
下面语句出现 ORA-14291 错误：
ALTER TABLE nonpart_table EXCHANGE PARTITION partition_name WITH TABLE part_table;
正常处理方法及步骤
以下子句正确：
ALTER TABLE part_table EXCHANGE PARTITION partition_name WITH TABLE nonpart_table ;
要交换复合分区与非分区表，应先分区非分区表，然后再进行交换操作：
ALTER TABLE nonpart_table （分区）EXCHANGE PARTITION partition_name WITH TABLE part_table;
