Thank you, arturo. I cannot believe such a basic need for every lazy developer is not implemented yet. It looks like such a tool might be my first contribution to Open Source community...8^)

I found interesting open source starting point, OracleTool, www.oracletool.com, which can generate CREATE statement with all the meat. I am just thinking about gutting some procedures from there and make them to generate half-decent HTML tables with important info.
If you want to look into it to re-use it in your code, check procedure tableDDL(). It is in perl...8^)

To make errors is human. But to make million errors per second, you need a computer.
