I work as a freelancer. And actually, I never ever processed logs.

Of course, sometimes I am given SQL access to server; but I never learnt SQL except for in action (i.e. things which I need right now).

And most of times I work with flat files. Even if they come from SQL they typically need a serious preprocessing before I can do a more adv analysis.

BTW: I have no problems with composing rather advanced queries. Just if SQL is a problem from someone (and, in case of doubt, it can't be Googled in no time) then I am curious how can get machine learning.
