MySQL使用 INTO INFILE/OUTFILE导入导出数据

1.使用SELECT ... INTO OUTFILE 以逗号分隔的方式将数据导入到一个csv文件中:

SELECT * FROM table1 INTO OUTFILE 'usr/data/data1.csv' FIELDS TERMINATED BY ','

2.将刚刚导出的文件data1.csv导入到表table1相同结构的table2中:
LOAD DATA INFILE 'usr/data/data1.csv' INTO TABLE table2 FIELDS TERMINATED BY ',' 
通用形式

1.使用select * into outfile 导出:

SELECT * FROM table1 INTO OUTFILE FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' 参数：
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

2.load导入

LOAD DATA INFILE 'usr/data/data1.csv' INTO TABLE table2 FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n'
