Add test cases for native queries and parameterized queries.

Hi Philippe,
I add some test cases that should pass for:
- native queries
- parameterized queries
- queries built from StringBuilder

Native queries should be easy to fix but parameterized queries must be far more complex if mixed with queries built from StringBuilder. I see a lot of that in code where developers add where clauses if a input parameter is not null.

Regards,
