导入

load data infile 'c:/test.csv'   
into table test [character set utf8]
fields terminated by ','  optionally enclosed by '"' escaped by '"'   
lines terminated by '
';

导出

select * from test 
into outfile 'c:/test.csv'   
fields terminated by ',' optionally enclosed by '"' escaped by '"'   
lines terminated by '
';   

如果要带上字段名用：

select * from (
	select 'col1','col2','col3','col4' union 
	(select col1,col2,col3,col4 from test where col1 = 'xxx' order by col1)
) tbl
