您好，我正试图在mysql中执行查询，但出现以下错误

查询：

1
 SELECT * FROM user_registration FULL OUTER JOIN user_details ON user_registration.email = user_details.gmail

错误是：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'OUTER JOIN dreams ON user_registration.email = user_details.gmail LIMIT 0, 25' at line 1

select * from user_registration ur right join user_details ud on ur.email = ud.gmail
