Ok so you want the advantage of SQL but aren't allowed to use a local instance of SQL Server? If you are allowed direct read access to the server may I recommend Database .Net It's basically SSMS but you can connect to many more datasources with ease (Such as Excel or Access) whilst still using SQL. It also requires no instance, it's an exe with no install.
So you could create an ETL query to pull the data from your production databases into a local Access database, or straight to an Excel report, then just run that daily through Database .NET?
Yes, you can use it too. I'm not sure there is anything that makes this specific to web developers. Its just a nice, portable database editor. A couple more that I like are:
Database.NET is pretty useful, and you can carry it on a USB stick. However, it only runs on Windows. DbVisualizer runs on Windows, Mac, and Linux.
