Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Run query on remote database and output results as csv

You can, of course, tell MySQL to output results to a file and dictate how to terminate lines, etc. But sometimes you don't have access to the file system MySQL is running on, complicating outputting your results to a CSV, necessitating either annoying hacks or this simple command :D

Know a better way?

If you can do better, submit your command here.

What others think

Not bad, but there's one possible problem.

If the database fields contain quotes ", then the csv will be corrupt.

To fix this, prefix your sed statement with:

sed 's/"/""/g'

Also, the two sed statements to add quotes to the beginning and end can be combined (simplified) to:

sed 's/.*/"\0"/'

Finally, I don't understand when I'd need the last sed part: sed 's/\n//g'

Combining the lot, I get:

... | sed 's/"/""/g;s/\t/","/g;s/.*/"\0"/' > ...
