I ran into a problem as I tried to create two TIMESTAMP columns in my database. One called created and one called updated. I figured it would be easy to set the default value of both to CURRENT_TIMESTAMP and then ON UPDATE CURRENT_TIMESTAMP for the updated column.

I'm running a php/mysql-driven website with a lot of visits and I'm considering the possibility of caching result-sets in shared memory in order to reduce database load. However, right now MySQL's query cache is enabled and it seems to be doing a pretty good job since if I disable query caching, the use of CPU jumps to 100% immediately. ...

I'm not too familiar with CakePHP, so pl...
