Insertion of the Hints to customize the queries execution modality.
Hints are comments that can be inserted in the string containing the query and that are able to change the behavior of Sadas Engine. The behavior of the engine is influenced by the hint only for the execution of the query containing it.
Moreover the activation of the hints in the engine and their usage in the string can be parameterized. The behavior of the engine can also be modified not only for the execution of the current query, but also persistently for the whole duration of the current connection. To do this it is possible to use some commands to set certain specific connection variables.
