1366不正确的整数值：将数据从CSV导入到mysql时出错

Question

我正试图使用​​LOAD DATA LOCAL INFILE将数据从CSV导入到MySQL。对于所谓的 “数” 有我收到错误1366不正确的整数值的所有空值的整数列：

我已经试过count = IF(@count='',NULL,@count)

CREATE TABLE MySchema.response：

CREATE TABLE MySchema.response 
(
`id` int, 
`name` varchar(500), 
`count` int, 
); 

将数据加载到表：

LOAD DATA LOCAL INFILE 'C:/response.csv' 
INTO TABLE MySchema.response 
FIELDS TERMINATED BY ',' optionally ENCLOSED by '"' 
ignore 1 lines 
(id, name, @count) 
SET count = IF(@count='',NULL,@count) 

样本CSV文件数据

1,abc, 

2,xyz, 

Answer 1

你忘了定义VAR，请参见下面正确LOAD DATA INFILE ...声明：

root@localhost [test]> SHOW CREATE TABLE `Response`\G 
*************************** 1. row *************************** 
     Table: Response 
Create Table: CREATE TABLE `Response` (
    `id` int(11) DEFAULT NULL, 
    `name` varchar(500) DEFAULT NULL, 
    `count` int(11) DEFAULT NULL 
) 

root@localhost [test]> LOAD DATA INFILE '~/Desktop/data.csv' INTO TABLE Response FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' (id, name, @count) SET count = IF(@count = '', NULL, @count); 

root@localhost [test]> SELECT * FROM `Response`; 
+------+------+-------+ 
| id | name | count | 
+------+------+-------+ 
| 1 | abc | NULL | 
| 2 | xyz | 12345 | 
+------+------+-------+ 

文件data.csv

1,abc, 
2,xyz,12345
