但是当我尝试删除 SYSTEM VERSIONING 时，我收到此消息错误：

MariaDB [nemo]> ALTER TABLE people DROP SYSTEM VERSIONING;
ERROR 4131 (HY000): Can not DROP SYSTEM VERSIONING for table `people` partitioned BY SYSTEM_TIME

问题：

在我的情况下如何删除系统版本控制？谢谢

【问题讨论】：

mysql不支持系统版本表，所以这个问题不适用于mysql。

PARITITION BY SYSTEM TIME 是一个系统版本的构造。

根据您收到的错误消息，您需要删除分区才能删除系统版本：

ALTER TABLE people REMOVE PARTITIONING
ALTER TABLE people DROP SYSTEM VERSIONING
