Question

我对MySQL很新，但我无法找到为什么我无法从命令行将csv文件导入我的数据库。输入文件对于PHPMyAdmin来说太大了，然后我尝试从命令行更新数据表。

这是从终端

运行的命令

LOAD DATA LOCAL INFILE "/home/meteo/PROJECTES/BASE-AEMET/TREBALL/PCP.csv" into TABLE precipitacion FIELDS TERMINATED BY ',' (CodigoEst, Fecha, Precipitacion, ValidPP);

这些是PCP.csv文件的结构

"7034",2000-01-01,0,"S"
"7034",2000-02-01,0,"S"
"7034",2000-03-01,0,"S"
"7034",2000-04-01,0,"S"
"7034",2000-05-01,0,"S"

但是sql查询的输出给出了这条消息

查询正常，0行受影响，65535警告（30,55秒）记录：1586445 删除：0跳过：1586445警告：4759335

并且表格中没有插入任何记录。

在查看警告时，我收到此消息

如何进行？愿这是一个简单的问题，但我被困在这里。在此先感谢您的帮助。

Answer 1

Code: 1265 Message: Data truncated for column表示您插入的值大于列允许的值。

Code: 1062 Message: Duplicate entry表示您为具有UNIQUE键的列插入值，并且该值已存在于该列的另一行中。

Answer 2

最后，将数据导入我的数据库的解决方案是将原始的大csv拆分为较小的文件。然后，从phpMyAdmin导入运行正常。

感谢您的建议。
