二 创建数据库、创建表user
create database youku; --创建数据库 use youku; -- 选择数据库 DROP TABLE IF EXISTS `user`; CREATE TABLE `user` ( `username` varchar(11) DEFAULT NULL, `userpwd` varchar(11) DEFAULT NULL, `age` int(11) DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8; //插入数据 INSERT INTO `user` VALUES (‘admin‘,‘admin‘,18),(‘root‘,‘root‘,18),(‘cat‘,‘cat‘,17),(‘dog‘,‘dog‘,15),(‘dog1‘,‘dog1‘,15),(‘zhu‘,‘zhu‘,21); -- 表数据导出 SELECT * FROM user INTO OUTFILE ‘F:/user.txt‘; -- 根据需要设置输出的格式,每一行数据‘,‘分隔,同时字符串型的数据用双引号""包含 SELECT * FROM user INTO OUTFILE ‘F:/user1.txt‘ Fields TERMINATED BY ‘,‘ OPTIONALLY ENCLOSED BY ‘"‘; -- 表数据导入 (注意,导入的数据的列数要对应表的各列) -- 先删除数据 use youku; delete from user where age>10; select * from user; LOAD DATA INFILE ‘F:/user.txt‘ INTO TABLE user; select * from user; -- 导入有特殊格式的表user1.txt(去除分隔号‘,‘和字串的引号“”) use youku; delete from user where age>10; select * from user; LOAD DATA INFILE ‘F:/user1.txt‘ INTO TABLE user Fields TERMINATED BY ‘,‘ OPTIONALLY ENCLOSED BY ‘"‘; select * from user;
=================
三 txt文件查看
-- 表数据导出 SELECT * FROM user INTO OUTFILE ‘F:/user.txt‘;
生成文件user.txt
admin admin 18
root root 18
cat cat 17
dog dog 15
dog1 dog1 15
zhu zhu 21
-- 根据需要设置输出的格式,每一行数据‘,‘分隔,同时字符串型的数据用双引号""包含 SELECT * FROM user INTO OUTFILE ‘F:/user1.txt‘ Fields TERMINATED BY ‘,‘ OPTIONALLY ENCLOSED BY ‘"‘;
生成文件 user1.txt
"admin","admin",18
"root","root",18
"cat","cat",17
"dog","dog",15
"dog1","dog1",15
"zhu","zhu",21
结语:数据的具体导入导出格式大家可以自己尝试一下。但个人建议涉及格式转换的话尽量先用其他工具,为防止出错还是尽量只转换纯文本列数据(无特殊格式)。
