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。
文件：test_csv.sql
Sql代码
use test;
create table test_info (
id integer not null,
content varchar(64) not null,
primary key (id)
);
delete from test_info;
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;
create table test_info (
id integer not null,
content varchar(64) not null,
primary key (id)
);
delete from test_info;
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;
文件：test.csv
Text代码
2010,"hello, line
suped
seped
""
end"
2010,"hello, line
suped
seped
""
end"
在Linux下如果经常要进行这样的导入导出操作，当然最好与Shell脚本结合起来，为了避免每次都要写格式参数，可以把这个串保存在变量中，如下所示：(文件mysql.sh)

使用示例如下：(文件test__csv.sh)
Bash代码
#!/bin/sh

# MYSQL_CSV_FORMAT="fields terminated by ',' optionally enclosed by '\"' escaped by '\"' lines terminated by '\r\n'"
echo "MYSQL_CSV_FORMAT=$MYSQL_CSV_FORMAT"
rm /tmp/test.csv
mysql -p --default-character-set=gbk -t --verbose test <

create table if not exists test_info (
id integer not null,
content varchar(64) not null,
primary key (id)
);
delete from test_info;
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';
