FULL OUTER JOIN是一种关联查询操作,它返回两个表中的所有记录,并将它们按照指定的条件进行关联。然而,MySQL不支持FULL OUTER JOIN操作。为了实现FULL OUTER JOIN的效果,我们可以使用UNION操作符或者结合使用LEFT JOIN和RIGHT JOIN。 虽然FULL OUTER JOIN在MySQL中不可用,但我们可以使用其他方法来达到相同的目的。根据具...
The code is like that because it was copied from the base compiler where "FULL OUTER JOIN" is supported. the behavior should be that using this on MySQL raises an error, which in fact is the case, as the DB rejects it. if for example mariadb decided to add "FULL OUTER JOIN", we ...
