> As we know StarRocks/Doris are based on jdbc::mysql protocol and they are
> both support full join. But their dialect are extended from Mysql which not
> support FULL JOIN, can refer to this Jira ticket:
> https://issues.apache.org/jira/browse/CALCITE-4619
> At the same time this Jira above not added a test case for full join plan, so
> maybe we need to support full join in StarRocks and Doris and add related
> test case for it.
>
> *full join test in StarRocks and Doris(connect link like:
> jdbc::mysql://startrocks.url:9030):*
> {code:java}
> select * from (select 1 as id,'aa' as name) as a full join (select 1 as id,
> 'bb' as name) as b on a.id=b.id;
> > 1, aa, 1, bb {code}
>
> test in mysql:
> {code:java}
> select * from (select 1 as id,'aa' as name) as a full join (select 1 as id,
> 'bb' as name) as b on a.id=b.id;
> > SQL error [1064] [42000]: You have an error in your SQL syntax; check the
> > manual that corresponds to your MySQL server version for the right syntax
> > to use near 'full join (select 1 as id, 'bb' as name) as b on a.id=b.id
> LIMIT 0, 200' at line 1 {code}
