I'm curious to know whether or not SQL tunning is covered in this book ?

Sometimes, from the SQL execution plan point of view, it's faster to construct an exists statement than submitting a straight join to database.

However, it's very hard to decide about that. Does HF SQL cover SQL tunning basic procedures and tips ?

Best Regards,
Edisandro.
