"ERROR 2013 (HY000): Lost connection to MySQL server during query" 正在加载数据

Question

当我尝试使用 load data 命令将数据加载到我的 MySQL（实际上是 MariaDB）table 时出现错误：

load data local infile '/tmp/my_data.tsv' 
into table my_schema.my_table
fields terminated by '\t' 
optionally enclosed by '"'
escaped by '\'
lines terminated by '\n';

尝试给出的解决方案 here and here 无效。

出于某种原因，当您加载的数据打破了外键约束时，MySQL 给出了这条模糊的错误消息（here 中有更详细的描述）。

我通过直接从命令行执行 load data 命令设法获得了正确的错误消息。即运行:

mysql -u username -p --local-infile --execute= \
"load data local infile '/tmp/my_data.tsv' into table my_schema.my_table \
fields terminated by '\t' optionally enclosed by '\"' escaped by '\\';"

给出了错误信息：

Cannot add or update a child row: a foreign key constraint fails 
(`my_schema`.`my_table`, CONSTRAINT `other_table` FOREIGN KEY
(`id`) REFERENCES `other_table` (`id`))

删除违反外键约束的行后，我能够导入我的数据。
