I have a typical ubuntu setup and a mysql database. I'm trying to find a way to set a cron job to export each table in the mysql db into individual .csvs into a folder on the server. I'm not entirely sure how to approach this, everything I've finding shows how to take multiple csvs into a mysql db but not the other way around. Any help would be greatly appreciated
You can use the MySQL command line cliet to execute a command something like
select * from someTable into outfile 'somFile.csv'
fields optionally enclosed by '"' terminated by ',' lines terminated by '
';
Stick that in an SQL script file (with additional SELECTs if appropriate) then you can execute:
mysql -u username --password=******** < sqlscript.sql
Add that command to cron with crontab -e and you should be done.
A couple of gotchas: - make sure the user that cron is executing as has appropriate rights to the filesystem - the mySQL user you're logging in as will need FILE privilege - you might need some extra commands to move the CSV files about after they're created.
