This function is great! Anyone know how to include the column names, table info, any extra miscellaneous info?

RE: file permission
I didn't get it :( for example, I'm using: SELECT * INTO OUTFILE 'result_a.csv' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '' LINES TERMINATED BY '\n' FROM lista_switches; But this only saves the rows of data, with no column name; I would like to store the column name so the .csv is easier to read. If MySQL has options for storing, for example, the date as the last row, first column, even better; although I think I see what you mean, it reallly depends on the sleect statement? I f I manage to display what I want with the select, I'll be able to store it? That should work... But I though there was a -include_column_names option or something :) Which way should I go?

Thanks! But I want to change the default setting of the file permission and ownership. (i.e. the file will be created with permission and ownerhsip according to my setting).

Re: file permission
You can't do that. The mysql server runs as user mysql, so it cannot create files owned by another user. If you run the mysql server as root (don't!), you might be able to do that, but I do not believe mysql has a facility for changing the owner of a file. You are better off running a script as the user you want to own the file and outputing the results via the script. j- k- On Tuesday 28 February 2006 19:18, unplug wrote: Thanks!

Re: file permission
Actually, here is my case. There is a script owned by user A running daily. script--- rm -rf /tmp/report.csv mysql -umysql -pabc table -e SELECT * into outfile '/tmp/report.csv' fields terminated by ',' lines terminated by '\n' FROM table; In the first run, a file with the following permission and ownership will be created. -rw-rw-rw- 1 mysql mysql 2489 Mar 1 11:30 report.csv In the seconde run, the script will failed as user A have no permission to remove the file. In order to run the script daily, ownership of the file should be changed to user A.

Re: File Permission
Since you don't show your grant statement, it is difficult tell you what the problem is. Since FILE is a global permission you need to grant it on *.* not somedatabase.* David Scott wrote: Greetings all I am not able to GRANT file permission to users.

Re: File Permission
Thank you Gerald. That was the problem. I thought I read that FILE permission could not be set to a specific table so I was using somedatabase.*.

Re: FILE Permission Security Question
At 11:13 PM -0400 5/8/01, A. Chris Nichols wrote: Hello everyone, I was wondering if anyone could help me out and explain a bit about the FILE permissions and how they relate to two particular scenarios: In both cases MySQL is running on SunOS 5.7 and running MySQL client version 3.22.23b MySQL UserA has permissions only on DatabaseA and is granted FILE permissions to all tables in that database Nope. The FILE privilege is one of the global privileges. You either have it or you don't. Doesn't depend on which databases you have access to. (The indicator for whether or not you have the FILE privilege is stored in the user table along with the other global privileges. That table isn't db-specific.) Scenario 1: If UserA connects to the database using the MySQL client What are the restrictions on what files that user can access using a LOAD DATA command? Are they dependent at all on the UNIX file permissions for the user who is logged in and actually connects to the database using the mysql -u... etc command? Do the UNIX permissions for the user that started the MySQL server have any effect on this? Is there anything configuration wise that might allow LOADing in other DBs or system files? What defines where outfiles can be written? The user who is logged in has nothing to do with the LOAD DATA (this is not true for LOAD DATA LOCAL, but that's not what you're asking about). There are two reasons for this: 1) you connect to the server using a MySQL user name, not your UNIX login name. (They might be the same, but that's just coincidence.) 2) The server can only access files that are accessible by the account whose ID the server runs as. This has nothing to do with either your MySQL user name *or* your UNIX login name. What defines where outfiles can be written are the privileges of the UNIX account under which the server runs. There's nothing special about this. If the server runs as root, it can access anything (which is why it's a bad bad bad idea to run the server as root). If the server runs as an ordinary user, it has that user's privileges. Scenario 2: If UserA's credentials are used to connect to the MySQL database using the Perl DBI Same question, what factors influence what files can be read in using a LOAD DATA command? What defines where outfiles can be written? The privileges of the UNIX account under which the server runs. Doesn't matter what MySQL user you connect to the server as. In both scenarios is there anything that can compromise this security such as the MySQL server running as root? (I know that's a big no-no) Right. Don't run the server as root. Run it as an ordinary user to limit the amount of damage it can do. (Or that users with the FILE privilege can make it do.) Also, I know I'm running an ancient version of MySQL, can anyone help me find out when that version was released? 3.22.23b? It will help me convince the right people that it's time for an upgrade! I've checked in the release notes section but I can't find anything about when particular releases were made... Not sure exactly, but I know it was prior to December 1999.
