Hi , I studied the join_table part of sql_yacc.yy and the the
convert_right_join() part from sql_parse.cc .
Sir to add the full outer join :
if we add a /*Full outer join variant */ , where first we will do
left outer join and then right outer join in that , after that
we can use the "UNION" part in /*Full outer join variant */ to join
the left outer join and right outer join table to get the full outer
join table.
Will this approach gonna work Sir? please guide me for this issue.Is
it completely wrong or need some modification?
Please read Igor Babaev comment about transformation here:

about direction, if no, please do not hesitate to ask.
