One of my current projects involved exporting some data from MySQL into Oracle. This being one of a limited number of times I've used MySQL, some things didn't work as I expected (expected as in work-like-Oracle does). And although mysql.com has some pretty nice online docs, it took a while to find what I wanted, not knowing exactly how to describe what it is I wanted. In the process, I found this interesting collection of MySQL Gotchas. A "gotcha" is a feature or function which works as advertised - but not as expected. Sounds like a synonym for PITA to me...
Good to see someone took the effort to compile a list. There's got to be something similar for Oracle somewhere...
