Few days back, Baron re-introduced MySQL's command line pager command and described some cool tricks with maatkit's mk-visual-explain (one of my favorite tools). Soon after reading it, I wished if it was possible to describe regex based (on query) paging. I have written a small hack, christened mysmartpager, that can actually do regex based paging for you. The idea is simple, write a relay that will redirect the output based on to the desired pager. The problem was complex, there was no direct way of getting to know the original query. There are a couple of indirect ways of doing so, but of course with hurdles:

April 14-17th is going to be an exciting time. Why? Because the 2008 MySQL Conference and Expo is going to be held in Santa Clara, CA. Who would want to miss out on a chance to lurk around, let alone talk to, some of the smartest people in the MySQL world? Well, those who don't have at least $1000+, of course. A 3 day pass to the conference without tutorials costs a whopping $1199. A full pass would dry up your pockets $1499.

Well, "good news everyone". Thanks to Sheeri Cabral of The Pythian Group, PlanetMySQL.org,
