但是当我尝试删除 SYSTEM VERSIONING 时，我收到了这条错误消息：

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：

如何在我的案例中删除系统版本控制？谢谢

Answer 1

ref: dbfiddle

PARITITION BY SYSTEM TIME 是系统版本化结构。

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控制：

ALTER TABLE people REMOVE PARTITIONING
ALTER TABLE people DROP SYSTEM VERSIONING

Mariadb 无法删除系统版本控制

Mariadb Can not drop System versioning
