Question

我正在尝试在表格中导入经典城市列表。我在AWS RDS上使用Mysql 5.7.22-log。这是表DDL：

CREATE TABLE `city` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `createdBy` varchar(255) DEFAULT NULL,
  `createdDate` datetime NOT NULL,
  `lastModifiedBy` varchar(255) DEFAULT NULL,
  `lastModifiedDate` datetime DEFAULT NULL,
  `sid` varchar(36) NOT NULL,
  `version` bigint(20) NOT NULL,
  `country` varchar(2) NOT NULL,
  `district` varchar(255) DEFAULT NULL,
  `name` varchar(255) NOT NULL,
  `region` varchar(255) DEFAULT NULL,
  `zipCode` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `UK_i22k5i5v70edpr8sn0f7qsqu8` (`sid`),
  UNIQUE KEY `UKprra9tj5gtk21kc3chb9skup9` (`name`,`district`,`country`)
) ENGINE=InnoDB AUTO_INCREMENT=8192 DEFAULT CHARSET=utf8

我有一个UTF-8 .csv文件，如下所示：

name;district;zipCode;region;country
Abano Terme;PD;35031;Veneto;IT
Abbadia Cerreto;LO;26834;Lombardia;IT
Abbadia Lariana;LC;23821;Lombardia;IT
Abbadia San Salvatore;SI;53021;Toscana;IT

我以这种方式导入数据：

LOAD DATA LOCAL INFILE 'C:\\City.csv' INTO TABLE City FIELDS TERMINATED BY ';' IGNORE 1 LINES
(NAME,district,zipCode,region,country)
SET `createdBy`='system',createdDate=NOW(),lastModifiedBy='system',lastModifiedDate=NOW(),sid=UUID(),`version`=1;

数据已导入，但是我对截断的数据有很多警告：

1 queries executed, 1 success, 0 errors, 1 warnings

Query: LOAD DATA LOCAL INFILE 'C:\\City.csv' INTO TABLE City FIELDS TERMINATED BY ';' IGNORE 1 LINES (n...

8103 row(s) affected, 8100 warning(s)

Note Code : 1265
Data truncated for column 'country' at row 6

Note Code : 1265
Data truncated for column 'country' at row 7

我不明白为什么，在csv文件中，contry值为2个字符。

我在做什么错了？

Answer 1

如果我想清楚地告诉您，则需要在“城市”表中将country属性的长度更改为两个以上，如下所示。

`country` varchar(50) NOT NULL,

Answer 2

您是否查看了加载了哪些数据？

默认情况下，LOAD DATA假定行以换行符终止，但是MSWindows（从MS-DOS继承，从CPM继承）使用回车符和换行符作为换行符。这样就可以看到：

name;district;zipCode;region;country\r
Abano Terme;PD;35031;Veneto;IT\r
Abbadia Cerreto;LO;26834;Lombardia;IT\r
Abbadia Lariana;LC;23821;Lombardia;IT\r
Abbadia San Salvatore;SI;53021;Toscana;IT\r

尝试：

LOAD DATA LOCAL INFILE 'C:\\City.csv' 
INTO TABLE City 
FIELDS TERMINATED BY ';'
LINES TERMINATED BY '\r\n' 
IGNORE 1 LINES
(NAME,district,zipCode,region,country)
SET `createdBy`='system'
,createdDate=NOW()
,lastModifiedBy='system'
,lastModifiedDate=NOW()
,sid=UUID()
,`version`=1;
