SQL Injection Attacks by Example

“SQL Injection” is subset of the an unverified/unsanitized user input vulnerability (“buffer overflows” are a different subset), and the idea is to convince the application to run SQL code that was not intended. If the application is creating SQL strings naively on the fly and then running them, it’s straightforward to create some real surprises.

We’ll note that this was a somewhat winding road with more than one wrong turn, and others with more experience will certainly have different — and better — approaches. But the fact that we were successful does suggest that we were not entirely misguided.

InnoDB slow? – PHPBuilder.com

MyISAM’s advantage is speed and the support of the FULLTEXT search capability. InnoDB sacrifices some speed in favor of transactions support.
