MySQL中导出CSV格式数据的SQL

MySQL中导出CSV格式数据的SQL语句样本如下：

Sql代码 
select * from test_info   
into outfile '/tmp/test.csv'   
fields terminated by ',' optionally enclosed by '"' escaped by '"'   
lines terminated by '\r\n';  

select * from test_info
into outfile '/tmp/test.csv'
fields terminated by ',' optionally enclosed by '"' escaped by '"'
lines terminated by '\r\n'; MySQL中导入CSV格式数据的SQL语句样本如下：

Sql代码 
load data infile '/tmp/test.csv'   
into table test_info    
fields terminated by ','  optionally enclosed by '"' escaped by '"'   
lines terminated by '\r\n';  

load data infile '/tmp/test.csv'
into table test_info 
fields terminated by ','  optionally enclosed by '"' escaped by '"'
lines terminated by '\r\n'; 里面最关键的部分就是格式参数

Sql代码 
fields terminated by ',' optionally enclosed by '"' escaped by '"'   
lines terminated by '\r\n'  

fields terminated by ',' optionally enclosed by '"' escaped by '"'
lines terminated by '\r\n' 这个参数是根据RFC4180文档设置的，该文档全称Common Format and MIME Type for Comma-Separated Values (CSV) Files，其中详细描述了CSV格式，其要点包括：

(1)字段之间以逗号分隔，数据行之间以\r\n分隔；

(2)字符串以半角双引号包围，字符串本身的双引号用两个双引号表示。

Sql代码

create table test_info (  
    id  integer not null,  
    content varchar(64) not null,  
    primary key (id)  
);

insert into test_info values (2010, 'hello, line  
suped  
seped  
"  
end'  
);  
 
select * from test_info;  
 
select * from test_info into outfile '/tmp/test.csv' fields terminated by ',' optionally enclosed by '"' escaped by '"' lines terminated by '\r\n';  
 
delete from test_info;  
 
load data infile '/tmp/test.csv' into table test_info  fields terminated by ','  optionally enclosed by '"' escaped by '"' lines terminated by '\r\n';  
 
select * from test_info;  
 
  

use test;
