Declare a cursor with the Finder::declare_cursor() method and next get the cursor with get_cursor():
morm::Cursor<MyObject> cursor = finder.
declare_cursor("mycursorname").
select().
raw("ORDER BY column_name ASC").
get_cursor();
The cursor now can be used with fetch.*() methods and then get() or get_list():
MyObject myobject = cursor.fetch_next().get();
std::list<MyObject> myobjects = cursor.fetch_forward_count(10).get_list();
Char type was converted to wchar_t and then was serialized as utf-8 stream.
Let char type will always be one char, of course it need to be a valid utf-8 sequence.
Let FT::dont_use_utf8 apply only to wchar_t and std::wstring
but ignore it if FT::hexadecimal or FT::binary are defined.
Now we have bool BaseExpression::esc_char(wchar_t val, pt::TextStream & stream) method
which (in most cases) will be used in derived classes.
Let wchar_t (and std::wstring) will be stored as 8 hex digits when using FT::hexadecimal
or FT::binary (and ignore FT::dont_use_utf8 in such a case).
fixed: when generating: insert, update or remove statements we have used prefixes for columns
but the table name was not set in ModelEnv (now we do not use prefixes in such statements)
changed: log_queries field moved from PostgreSQLConnector to DbConnector

w klasie bazowej mamy virtualne get_value() z innymi parametrami

this allowes us to call query() recursively (from after_select() callback)
