从CSV导入的MySql

Question

我有一个包含三列NODEID，X，Y的表。NODEID是主键，它被设置为INT（4）为AUTOINCREMENT。我希望通过phpmyadmin导入从CSV导入更多数据。问题：

1. CSV的格式是什么样的？
2. 这是可能或正在导入基本上只是用CSV替换整个数据？

截至目前CSV样子：

1,-105.057578,39.785603 
2,-105.038646,39.771132 
3,-105.013045,39.771727 
5,-105.045721,39.762055 
6,-105.031777,39.76206 
7,-105.046015,39.72835 
8,-105.029796,39.728304 
10,-104.930863,39.754579 
11,-104.910624,39.754644 
13,-104.930959,39.74367 
16,-105.045802,39.685253 
17,-105.032149,39.688557 
18,-105.060891,39.657622 
20,-105.042257,39.644086 

等等

Answer 1

更改的SQL的phpmyadmin将运行到这一点：

LOAD DATA INFILE '*FILEPATH*' 
INTO TABLE *table* 
(X, Y); 

（你才会必须改变最后一行） 而你的csv应该看起来像

-105.057578,39.785603 
-105.038646,39.771132 
-105.013045,39.771727 
-105.045721,39.762055 
-105.031777,39.76206 
-105.046015,39.72835 

最后一行告诉MySQL仅查找这两列数据并为其他列插入null。如预期的那样，NULL值将自动递增。
