Update: JetBrains has been working on a plug-in/standalone SQL client similar to MySQL Workbench. I personally prefer Workbench, or just the plain terminal application for most things. Open your browser and navigate to the URL you created for it, and you can play with SQL in the 'SQL' tab, again to your heart's content. You'll need to install the php5 and php5-mysql packages, and a web server (such as lighttp or apache, either of which PhpMyAdmin should give you the option to configure), then install the phpmyadmin package. PHPMyAdmin This is somewhere between, and is a web-based solution. You can find this in the repos as the mysql-workbench package. MySQL Workbench This is a more full-featured database management GUI more similar to Management Tools than LinqPad, but it features a SQL query editor that allows you to run queries to your heart's content. That will bring up a mysql console, which you can then run SQL queries directly in. You'll have to install mysql-client (which you'll probably need if you do any PHP/Python/Ruby development, anyway), but then, you can open up a terminal and type in mysql -u -p ( -p if the mysql user has a password, otherwise just leave the -p off). Net syntax (you can, however, get similar syntaxes by getting into some of the languages and frameworks, the most closely-resembling probably being Ruby or Python). The biggest difference will be that you won't be able to use Linq syntax, because Linq is a. Additionally, you'll probably want create and populate a database to play around with.

In that sense, you have several options, but remember that you'll need to install MySQL server ( sudo apt-get install mysql-server in terminal) to use them.

LinqPad is basically a gui front end for MS-SQL Server.
