Small causes, big effects. Seemingly small mistakes can have enormous consequences in database software development. Sql statements run for hours instead of seconds or minutes.I have been correcting software that runs on the Oracle database for 20 years. See my best of the most common errors in database-driven software. I deliberately chose dramatic examples so that the mistakes in each case are really clear. If twice as fast does not make a point, a thousand times faster rather will.
