polardb-mysql 数据库，add_index_outline语法，如何在多个表中使用索引？

下面语句，如何add_index_outline使用，index(r idx_createDate) index(c idx_id)这两个索引？
```select count(*)
from
table1 r
left join table2 c
on r.channel_id = c.id
left join table3 m on m.No = r.No
left join table4 master on master.id = m.chantId
where
1 = 1
and c.uuid = r.aChannelCode
and r.createDate >= timestamp('2024-10-17 00:00:00.000000')
and r.createDate <= timestamp('2024-12-24 23:59:59.999999')
order by
r.id desc
LIMIT
15

或者
在当我使用UNION ALL拼接语句时，如何使用add_index_outline

```dbms_outln.add_index_outline('<Schema_name>','<Digest>',<Position>,'<Type>','<Hint>','<Scope>','<Query>');
