Question

基本上我想将csv文件加载到两个mysql表中，其中一个表中只有特定字段，而另一个表中有一些其他字段

这些是表定义-https://imgur.com/c7Scdkm 这是我要加载的文件-http://s000.tinyupload.com/index.php?file_id=19140190054505912011

当我运行此命令=

load data infile "C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/careerbuilder_dataanalytics.csv" into table dataanalyst_ncr FIELDS TERMINATED BY ',' IGNORE 1 ROWS(@col1,@col2,@col3,@col4) set Job_title=@col3,Company_name=@col1,links=@col4,job_desc=@col2;

它显示此错误-

Error Code: 1262. Row 1 was truncated; it contained more data than there were input columns

我想将文件的每一列加载到表中的特定列

u标头后-数据前（删除）在CSV中有一个空行。您必须形成两个语句才能将数据加载到两个表中要加载数据，您必须使用以下命令启动mysql

mysql -u root -p --local-infile=1

文字代码有效

load data local infile '/home/infiniti/Downloads/careerbuilder_dataanalytics.csv' into table dataanalyst_ncr
fields terminated by ','
lines terminated by '\n'
ignore 1 lines
(@col1, @col2, @col3, @col4, @col5, @col6)
set 
job_title = @col3, company_name = @col1, job_desc = @col2, job_id = 0, links=@col4

mysql> create table dataanalyst_ncr ( job_title text, company_name text, links text, job_desc text, job_id int primary key auto_increment, last_updated_on timestamp) ;
Query OK, 0 rows affected (0.58 sec)


mysql> desc dataanalyst_ncr;
