MariaDB：ALTER TABLE 命令适用于一个 table，但不适用于另一个
MariaDB: ALTER TABLE command works on one table, but not the other
我在 MariaDB 数据库中有两个表（Django 模型）：coredb_vsatservicerate 和 coredb_simservicerate。
MariaDB [servicedbtest]> SHOW CREATE TABLE `coredb_simservicerate`;

对于 coredb_simservicerate 此命令工作正常：
MariaDB [servicedbtest]> ALTER TABLE `coredb_simservicerate` MODIFY `price` numeric(9, 2) NULL;
Query OK, 0 rows affected (0.001 sec)
Records: 0 Duplicates: 0 Warnings: 0
对于 coredb_vsatservicerate，此类似命令会引发错误：
MariaDB [servicedbtest]> ALTER TABLE `coredb_vsatservicerate` MODIFY `price` decimal(9, 2) NULL;
ERROR 1054 (42S22): Unknown column '`servicedbtest`.`U0`.`year`' in 'CHECK'
我查看了 MariaDB 的文档，但仍然不知道为什么。
你能帮帮我吗？
这是 MariaDB 中的错误吗？

这是 MariaDB 10.3 中的错误吗？
我使用 MariaDB 10.5 docker-容器 (https://hub.docker.com/r/mariadb/columnstore) 对此进行了测试，但问题并未发生。
这似乎是当前在 Debian-Stable APT 存储库中的版本中的一个 Bug。
升级到 10.5 解决了这个问题。
