MySQL INTO OUTFILE/INFILE导出导入数据

--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 'D:\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 'D:\log1.txt' INTO TABLE aa.log2 FIELDS TERMINATED BY ','

-- 使用select * into outfile 导出:

SELECT * INTO OUTFILE 'd:\test.txt' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '
' FROM test.table

-- 导入

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

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 ' ' 换行符
