The AQL language reference is needed


#1

I need the full specification of the AQL in the form of a user manual a formal grammar, etc.
I found a very basic introduction here: http://www.paradigm4.com/HTMLmanual/14.8/scidb_ug/ch09s01.html but I need the detailed specification of all the elements, clauses, and so on.
Would you please point me to the right place?
