mysql导出，导入csv文件 多出空记录

1，导出表table_a的数据为CSV文件a.csv

windows下的情况：

select * from table_a  

into outfile '/tmp/a.csv'   

fields terminated by ',' optionally enclosed by '"' escaped by '"'   

lines terminated by '\r\n';      

linux下将lines terminated by '\r\n'; 改为lines terminated by '\n';

否则会多出两条空记录

2，将a.csv导入至表table_a

load data infile '/tmp/a.csv'

into table table_a  

fields terminated by ','  optionally enclosed by '"' escaped by '"'

lines terminated by '\r\n';

同理：

linux下将lines terminated by '\r\n'; 改为lines terminated by '\n';
