Question

I'm trying to do a SELECT INTO OUTFILE and I'm getting the following error:

General error: 1 Can't create/write to file '/home/jason/projects/mcif/web/downloads/dump.csv' (Errcode: 13). Failing Query: "
SELECT name
INTO OUTFILE '/home/jason/projects/mcif/web/downloads/dump.csv'
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
FROM account a

I know what the problem probably is: my downloads folder isn't writable by my MySQL user. I don't know how to solve this problem for two reasons:

  • I don't know how to find out what the MySQL user is
  • I don't know how to add the MySQL user to the users who are able to write to the downloads folder

I'm on Ubuntu Linux. Can someone help me get past those two things?

Was it helpful?

Solution

write the file /tmp/dump.csv and the copy it over.. That will let you see who is running what. My guess is that you are doing this from the web and the client is running as the web server process...

OTHER TIPS

mysql -u USERNAME --password=PASSWORD --database=DATABASE --execute='SELECT FIELD, FIELD FROM TABLE LIMIT 0, 10000 ' -X > file.xml

Here's a discussion that may help: How can I have MySQL write outfiles as a different user?

Also, please try to avoid clouding your questions with fluff. In your case, you already know it's a permissions issue, so all of your SQL joins and tables don't matter. You could have simply used one field from one table in your select, to demonstrate the problem without clouding things up.

the client will probably be mysqld. you must change apparmor authorizations and it will work fine. check out this answer
