将 CSV 导入 mySQL答案

【问题标题】：Importing a CSV to mySQL将 CSV 导入 mySQL
【发布时间】：2017-01-12 16:56:42
【问题描述】：

我有一个 CSV 文件，其中包含一个可以包含逗号分隔值列表的列。

我使用以下 SQL 语句导入数据：

LOAD DATA LOCAL INFILE 'C:/tmp/geography.csv' 
INTO TABLE geography 
FIELDS TERMINATED BY ',' 
ENCLOSED BY '"'
IGNORE 1 ROWS;

但是，当它到达包含逗号分隔值列表的行时，它会中断导入。

数据格式如下：

id,zip,location_type,primary_city,state,county,area_codes
  ,00501,UNIQUE,Holtsville,NY,Suffolk County,631
  ,00601,STANDARD,Adjuntas,PR,Adjuntas Municipio,"787,939"

\N,00601,STANDARD,Adjuntas,PR,Adjuntas Municipio,"787,939"
