--------------------------------------------------------------

[~vinx13], can you also fix C++ Query Example? You can find it at {{cpp/examples/query-example/src/query_example.cpp}}.
There you can find lines like 
{code}
SqlQuery qry(PERSON_TYPE, sql);
//...
qry = SqlQuery(PERSON_TYPE, sql);
{code}
That's where {{ClearArguments()}} call could be used. There are several places like that in
the example.

> Currently, there is method {{AddArgument}} for {{SqlQuery}} and {{SqlFieldsQuery}}, but
there is no way to reset arguments for query once they are set. This leads to inconvenience
when user want to call the same query with different arguments as they need to re-create exactly
the same query but set different arguments for it.
