MySQL-LOAD-DATA-LOCAL-INFILE-Skipped
使用MySQL的LOAD DATA LOCAL INFILE 载入文件时可能会遇到部分记录没有导入(在执行结果反馈的信息中显示为Skipped: n 的情况.
如果你想知道哪些记录被跳过了，请使用LOAD DATA INFILE，它不会跳过那些记录，而是提示错误和出错的原因。
以下是MySQL文档中关于这个问题的tips：

If you get “Skipped records” using “LOAD DATA LOCAL INFILE” copy the data file to the actual database server and do the load without the “LOCAL” keyword.
This will then stop when an error occurs, 9 times out of 10 it will be index issues and you will know why there are skipped records.
e.g.
LOAD DATA LOCAL INFILE ‘myinfile.txt’;
Query OK, 288168 rows affected (1 min 44.49 sec)
Records: 494522 Deleted: 0 Skipped: 206354 Warnings: 0
LOAD DATA INFILE ‘/data/input/myinfile.txt’;
Query OK, 252243 rows affected (0.02 sec)
ERROR 1062 (23000): Duplicate entry ’5935009001-2008-08-03 04:19:18′ for key 1
