mysql - 使用csv从oracle导入到mysql

Question

我有一个从 oracle 数据库导出的 csv 文件(12 GB)，

格式如下

6436,,N,,,,,,,,,,,,04/01/1999,04/01/1999,352,1270,1270,406,406,1999,1,31/01/1999,0,88,0,A,11/12/2005,N,0,11/12/2005,,,,1270,1,0,,2974,,,,,,,,,,,,,,,,,,,,,,,,

如您所见，它有很多空值(大部分是整数)，当我将其导入 mysql 数据库时，它用零填充空值

喜欢，

6436,0,0,,0,0,0,0,0,0,0,0,0,0,4,04/01/1999,04/01/1999,1270,1270,406,406,1999,1,31,31/01/1999,88,0,A,11/12/2005,N,0,11/12/2005,0,0,0,1270,1,0,,2974,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,,,0,0,00/00/0000,0,,0,0

这里真正的问题是什么？谢谢。

我通过 @Marc B 的有用评论弄清楚了

我写了类似的东西

LOAD DATA LOCAL INFILE '/path/data.csv' INTO TABLE table_name
FIELDS TERMINATED BY ','
IGNORE 1 LINES
(columns with @)

SET
   column = IF(length(@column)= 0,null,@column),
   date = str_to_date(@date, '%d/%m/%Y');
