Why is a full outer join error in SQL running?

MySQL does not support full outer join, how to do full connection (enterprise version can support)

select s.camp_id,s.camp_name,k.read_flag from sony_push s full outer join `sony_push detail` k on s.camp_id=k.camp_id;

Error:

select s.camp_id,s.camp_name,k.read_flag from sony_push s full outer join `sony_push detail` k on s.camp_id=k.camp_id

Ordinary MySQL does not seem to support full outer join, it can be handled as follows:

select s.camp_id,s.camp_name,k.read_flag from sony_push s left join `sony_push detail` k on s.camp_id=k.camp_id union select s.camp_id,s.camp_name,k.read_flag from sony_push s right join `sony_push detail` k on s.camp_id=k.camp_id;
