Comments on: Optimize Hierarchy Queries with a Transitive Closure Table http://kylecordes.com/2008/01/13/transitive-closure/ Kyle Cordes's Software Site Sat, 30 Aug 2008 07:48:43 +0000 http://wordpress.org/?v=2.0.11 by: Craig Buchek http://kylecordes.com/2008/01/13/transitive-closure/#comment-15156 Tue, 15 Jan 2008 18:11:38 +0000 http://kylecordes.com/2008/01/13/transitive-closure/#comment-15156 Thanks for sharing this. I read your article on Celko's method, and followed up by reading the original articles by Celko. Seems like a good method in some situations, but Celko's method would seem to have poor insert/update performance as well, due to having to update, on average, half of the records in the table. I'd be interested in reading about more techniques like these. Thanks for sharing this. I read your article on Celko’s method, and followed up by reading the original articles by Celko.
