PLSQL. Too easy for its own good?

PLSQL is a very easy to learn programming language. Deceivingly easy.Recently I saw what happens when you learn the basics and think "this is so simple, I know enough".I was working for a client (no, I will not reveal their name) where the databases that I had to work with were built by people with obviously just a very basic understanding of the Oracle database and especially PLSQL.Many times a day I was shaking my head over the solutions that had been invented.I would like to take you along on a journey through some of the things that I saw there.Mainly for fun, because I hope you will already know that these things are not the way to do it.If you see something and think "that's how I would have done it", don't be ashamed. None of us knows everything.We all make mistakes.We all do stupid things.But, if you think "I could have done that" with all of the examples ...... I know a client for you :D
