我有一个文件,可以包含3到4列数字,用逗号分隔.当空字段位于行的末尾时,将定义空字段:

1,2,3,4,5
1,2,3,,5
1,2,3

下表是在MySQL中创建的:

+-------+--------+------+-----+---------+-------+
| Field | Type   | Null | Key | Default | Extra |
+-------+--------+------+-----+---------+-------+
| one   | int(1) | YES  |     | NULL    |       | 
| two   | int(1) | YES  |     | NULL    |       | 
| three | int(1) | YES  |     | NULL    |       | 
| four  | int(1) | YES  |     | NULL    |       | 
| five  | int(1) | YES  |     | NULL    |       | 
+-------+--------+------+-----+---------+-------+
