only true for freelancers. As a professional programer I must tell you your mistaken. have come accross many more companies (I'm talking big buisness) which use Oracle\MySQL in their website's backends than MySQL.

The reason for this being MySQL is OpenSource so it has less support and is seen as less secure (since any hacker can see the code it runs on. this offcourse isn't accurate, since OpenSource projects are ususally more secure, because more people have had their eye on it and found it's flaws, but big companies preffer "security by obscurity")

Plus MySQL misses many features such as subselect and such things that are needed in proper software

Edit: Silly me, MySQL supports SubSelects now, dosn't it?
