mysql查询结果导出文件，导入文件

mysql查询结果导出/输出/写入到文件

方法一：

直接执行命令：

mysql> select count(1) fromtable  into outfile'/tmp/test.xls';

Query OK, 31 rows affected (0.00 sec)

在目录/tmp/下会产生文件test.xls

遇到的问题：

mysql> select count(1) fromtable   into outfile'/data/test.xls';

报错：

ERROR 1 (HY000): Can't create/write to file '/data/test.xls'(Errcode: 13)

可能原因：mysql没有向/data/下写的权限

方法二：

查询都自动写入文件：

mysql> pager cat > /tmp/test.txt ;

PAGER set to 'cat > /tmp/test.txt'

之后的所有查询结果都自动写入/tmp/test.txt'，并前后覆盖

mysql> select * from table ;

30 rows in set (0.59 sec)

在框口不再显示查询结果

注意：这里只是将查询结果分页显示，然后重定向到文件

方法三：

跳出mysql命令行

[root@SHNHDX63-146 ~]# mysql -h 127.0.0.1 -u root -p XXXX -P 3306-e "select * from table"  > /tmp/test/txt

--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:

点击(此处)折叠或打开

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

点击(此处)折叠或打开

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

-- 使用select * into outfile 导出

点击(此处)折叠或打开

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

-- 导入

点击(此处)折叠或打开

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
