我希望将其转换为行和列，以便可以将其存储在数据库中。我在 MariaDB 上尝试了以下操作：
LOAD XML LOCAL INFILE '<path>.xml'
-> INTO TABLE mytbl(id, rep, c_date, D_name,...);
但它导致错误 ERROR 1148 (42000): The used command is not allowed with this MariaDB version 。怎么出去把xml文件转成行和表？
我在 Xampp 上使用 MariaDB。
编辑：版本 10.1.19-MariaDB

【参考方案1】：我无法重现该问题。

见LOAD XML。
更新
检查服务器系统变量local_infile的值：
MariaDB [_]> SHOW VARIABLES WHERE `Variable_name` = 'local_infile';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| local_infile | ON |

可能是 32 位与 64 位的问题。我在 32 位系统上并通过 Xampp 运行 MariaDB。我复制了您执行的确切步骤，但仍然遇到相同的错误。以上是关于如何在 Xampp 上使用 MariaDB 将 XML 文件转换为行和列？的主要内容，如果未能解决你的问题，请参考以下文章
