从CSV导入MySql

Question

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

1. CSV的格式是什么样的？
2. 这是可能还是导入基本上只是用CSV替换整个数据？

截至目前，CSV看起来像：

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

将phpmyadmin将运行的SQL更改为：

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

（你只需要改变最后一行） 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只查找这两列数据，并为任何其他列插入null。 NULL值将按预期自动递增。
