I met up with an old friend recently. Deb and I were in Toronto, hometown of a certain Simon Jennings.
Apart from being a top bloke, Simon was also my first mentor in the mysterious ways of SQL, a sort of Obi-Wan Kenobi to my Anakin Skywalker, but without the light-sabers.
Ah those heady days when the world was young…and I first discovered ROWNUM.
That pseudo column was one I used often when investigating the structure and data within tables. It was also, the source of some confusion.
