Hi group, I'm currently searching for lecture about SQL in general.
There are a lot of books. But all of them, at least those I had a look
into, are far too explanatory for me. I mean they introduce some
conecept, construct or language feature by presenting an example,
which it is applied to and leave you allone. That is not really the
stuff I can deal with. The other way round is much easier for me I
think.
Are there any books, web sites or other sources out there with
a more formal look on SQL?

Thanks in advance
