However, the trees/hierarchies book either predates this, or the chapters were copied from SQL for Smarties without modification. But when talking about this topic, OQGRAPH is so much easier than all this. Kinda makes it obsolete ;-) I’ve been in touch with Joe since the release of MySQL 5.0 years ago, and he did revise his opinion on MySQL based on the 5.0 feature set and cleanups.
