It depends on what you mean by "guide".
What do you expect from it?

Your queries will have to start from a good, if not excellent, ERD. No matter how good your queries are, if your ERD contains flaws, there is no way to correct anything at all. What Oracle DB are you using?

This will not learn you SQL (this is not a tutorial) but how to write good SQL.
