QUSEFULS Quick and Useful PL/SQL Tips

A Quseful is a Quick and Useful (as opposed to Quick and Dirty) tip on now to write programs in the Oracle PL/SQL language more effectively. Each Quseful contains a description of the tip ("What's the point?"), some PL/SQL code you can install in your environment to implement the tip ("Show me the code!"), an example of how to use the code to help you get your job done ("How do I use it?").
