MySql 'INTO OUTFILE ' from MySql commandline - mysql

Question

Here is my(dummy) query, which runs fine on the machine where mysql-server is hosted BUT fails on another machine, when I connect using the same user. (root)
SELECT *
FROM data
INTO OUTFILE '/tmp/dump.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n';
Error I get on mysql> prompt :
ERROR 1045 (28000): Access denied for user 'root'#'foobar.com' (using password: YES)
I have granted "ALL PRIVILEGES" to 'root'#'%'
Am I missing something ?
Adding some more data :
Following query works fine , which means the user is connected to right database and has read permission at the least.
SELECT *
FROM data limit 5;
I did do a server side FLUSH privileges;
How much time I am supposed to wait ? Any ballpark number ? I doubt it would be longer than few minutes.

Answer 1

Make sure you have created an account 'root'#'foobar.com' on the server. You can check it like this:
use information_schema;
select user, host from user;
mysql> select user, host from user;
+------+-----------+
| user | host |
+------+-----------+
| root | 127.0.0.1 |
| root | ::1 |
| root | localhost |
+------+-----------+
3 rows in set (0.00 sec)
You might also have an issue mixing wild card users (%) and users with explicit host, if both match mysql should deny access.

Answer 2

After looking at the error number ERROR 1045 (28000) following are the possible reasons why you are getting this error. Assuming user here is mysql user but not Linux/Windows user of the machine
You are trying to connect to a different TCP/IP port from which the server is listening. Use --port option to correct this.
Check the server configuration whether it is allowing network connection if you are trying to connect from a remote machine. Check --skip-networking option in configuration file
If bind-address=127.0.0.1 then mysql server will listen only the local connections and it will not listen to remote connections
May be a firewall is blocking your connection. To verify this Telnet or ssh to the server from a remote machine. As shown below.
$telnet 192.168.1.1 3306
In the above query you are trying to write a csv file from the query. Make sure that you have the appropriate user permissions to write the file.
As you said you have already did FLUSH PREVILEGES. Try to use the mysqladmin flush-previleges from the root prompt for you machine.
I have given some ideas to debug your problem. Probably above solutions will help you in solving your problem. Cheers
