Hi Im new to the forums, anyways I've had little experience with SQL in general (mainly a class+research on my own) But I am looking to really dive deep into it, I have 6 years programming experience but I really want to Get my Certification in at least one of the major SQL branches.

Anyways, im most familiar with Mysql, I know a decent amount. But how much different is Oracle syntax (or statements) compared to the other 2 (MySql, MS SQL 2008)
And how hard is it to pick up when comparing the three. I also realize I am a newb so my terminology might be off, but I plan on spending a good 5 months learning from books/and researching on my own from now to really get a good grip on things before I take the certification exams. Since alot of Jobs around here REALLY look positively at these certifications.

Thanks!
