MySQL INTO OUTFILE导出导入数据|mysqldump

--使用SELECT ... INTO OUTFILE 以逗号分隔字段的方式将数据导入到一个文件中:

SELECT * INTO OUTFILE 'C:\\log1.txt' FIELDS TERMINATED BY ',' FROM log.log1

--将刚刚导出的文件log1.txt导入到表log1相同结构的LOG2中

LOAD DATA INFILE 'C:\\log1.txt' INTO TABLE aa.log2 FIELDS TERMINATED BY ',';

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-- 使用select * into outfile 导出

SELECT * INTO OUTFILE '/tmp/fi.txt' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' FROM test.fi;

-- 导入

LOAD DATA INFILE '/tmp/fi.txt' INTO TABLE test.fii FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n';

总结：
FIELDS TERMINATED BY ',' 字段间分割符
OPTIONALLY ENCLOSED BY '"' 将字段包围 对数值型无效
LINES TERMINATED BY '\n' 换行符
