I need a online website to test MySQL statements (some sort of sandbox). Bonus points if you can store code and share it with other people. Something similar to jsfiddle.net for JavaScript. It allows code testing in a safe secure environment.
Theres an sql formatting tool that also reports syntax errors:

I was wondering how MySQL (and other databases for that matter) work under the hood. Do they use standard C I/O calls like fseek to find a record?
Here is the link to the source code. From a quick review of the file I can confirm that there are multiple check that is been done before and after an insert. It's actually a great idea to review the whole file very interesting.

I need to put a number of texts into my MySQL database via a manual query. The texts contain quotes, newlines, comment dashes ('--') and probably other syntax errors. Is there an online tool where I can paste in raw text and convert it to the query-escaped version?
Google gives me
http://www.freeformatter.com/string-escaper.html
and
http://www.freeformatter.com/sql-escape.html
Is this sufficient for you?

Is there any site where I can get good database with practice queries to solve. I am seeing a lot on internet, but mostly looks like beginner level.
Check out SQL Zoo: http://sqlzoo.net/
See http://www.w3schools.com/sql/default.asp ... I first started with that then I made up a database with 5 or 6 tables and tried myself subqueries and so on...

I need reproduce the exact same environment of a system in production, it's working with mysql 4.1.3b-beta-nt-max version, where I can get this exact version? I have looking with google but it seems like it's no longer available anywhere.
Thanks.
Try searching historical databases such as
http://www.oldapps.com/mysql_server.php?old_mysql_server=131
...in a pinch, you can install a "similar" version (such as the one above, 4.1.3beta-win), and then replace the binaries with the production ones. MySQL doesn't do strange things with the registry, so this procedure should suffice.

I am using the Business Objects Data Integrator tool and I want to run it from the command line so I can setup some automated unit testing.
Does anyone know if there is a command line to run it?

Perhaps pp65-66 are what you want? I confess to never having tried it myself, but it looks like it should work. :)
