【问题描述】：
最近，我在从 CSV 文件导入时遇到问题。我正在使用
MariaDB : 10.3.32-MariaDB-0ubuntu0.20.04.1
On Ubuntu : Ubuntu 20.04.3 LTS
我正在使用这个命令
LOAD DATA LOCAL INFILE '/path_to_file/data.csv' INTO TABLE tab
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES;
搜索并尝试后，我发现我只能从 tmp 文件夹加载文件。即
SELECT load_file('/tmp/data.csv');
但它在其他路径上不起作用。
其次，我发现即使 CSV 文件存在于 tmp 文件夹中；如果它包含很多字段，那么 MariaDB 将再次无法加载。主要问题是LOAD DATA 命令没有给出任何类型的错误甚至警告；除非文件不存在。除此之外没有任何显示。并且没有导入任何内容。
我只成功地从 tmp 文件夹导入了非常简单的 CSV
我怀疑是这样的
-
MariaDB 已经更新，在这个新版本中，有一些标志或配置选项禁止 MariaDB 从 tmp 文件夹以外导入 CSV 文件和
-
MariaDB 将无法加载 CSV，因为一些未知问题，可能是一些特殊字符（我确保其中没有任何内容）。
-
必须有一些选项使 MariaDB 产生详细的错误和警告日志。我不知道。
/var/log/mysql/error.log文件除外。其中不包含任何包含未能加载 CSV 的信息。
任何帮助将不胜感激。
以下是 CSV 的第一条记录。实际 CSV 包含 49 个字段和 1862 条记录（但以下示例仅包含一条记录）
