Note: Developer knowledge needed
SQL Query WA, is a small web based tool that I rushed together, in order to allow me to do quick queries on database. It written as web application, so you will need an 'application server' such as Tomcat to run it.
No JDBC drivers are installed by default, so you will need to get the one you need and put in the 'lib' folder of the web application.
This project is made available as an 'Eclipse' project, so you will need some development knowledge in order to make use of it. I will change this in the future, but at this point in time I have other priorities.
