导入具有多种自定义日期格式的 csv mysql

Question

我必须将 csv 导入到具有有趣日期格式的 mysql 数据库中，所以我决定使用 STR_TO_Date() 来转换它，但是它在第二次转换时出现错误我尝试对日期进行多次转换。

LOAD DATA LOCAL INFILE 'e:/the.csv' INTO TABLE data FIELDS OPTIONALLY ENCLOSED BY '"' TERMINATED BY ',' LINES TERMINATED BY '\n' IGNORE 1 ROWS (ID, UID, Barcode, Name, @Start, @End, Seconds) SET Start = STR_TO_DATE(@Start, '%d/%c/%Y %H:%i') SET End = STR_TO_DATE(@End, '%d/%c/%Y %H:%i')

我的数据库看起来是这样的：

ID  UID     Barcode Name        Start               End                 Seconds
29  12345   BBB6168 namehere    09/12/2014 18:00    09/12/2014 18:09    538
30  12345   AAA6168 namehere    10/12/2014 11:01    10/12/2014 11:02    4
31  AAAAA   ABC6084 namehere    10/12/2014 11:34    10/12/2014 11:34    5

我该如何解决这个问题？

Answer 1

正如 Barranka 所提到的，最好导入 table 字符串 (varchar) 列，然后运行插入到最终的 table.

LOAD DATA LOCAL INFILE 'e:/the.csv'
INTO TABLE data_temp_strings
FIELDS OPTIONALLY ENCLOSED BY '"' TERMINATED BY ','
LINES TERMINATED BY '\n'
IGNORE 1 ROWS
(ID, UID, Barcode, Name, StartStr, EndStr, Seconds);


INSERT INTO data (ID,UID,Barcode,Name,Start,End,Seconds)
SELECT  ID,
        UID,
        Barcode,
        Name,
        STR_TO_DATE(StartStr, '%d/%c/%Y %H:%i'),
        STR_TO_DATE(EndStr, '%d/%c/%Y %H:%i'),
        Seconds
FROM   data_temp_strings;

Answer 2

根据MySQL documentation for LOAD DATA INFILE，代码如下：

LOAD DATA LOCAL INFILE 'e:/the.csv'
INTO TABLE data
FIELDS OPTIONALLY ENCLOSED BY '"' TERMINATED BY ','
LINES TERMINATED BY '\n'
IGNORE 1 ROWS
(ID, UID, Barcode, Name, @Start, @End, Seconds)
SET Start = STR_TO_DATE(@Start, '%d/%c/%Y %H:%i'),
    End = STR_TO_DATE(@End, '%d/%c/%Y %H:%i');
