Question

以下查询为我提供了特定日期的最新日期/时间。

select * 
from calendar c 
where c.date= to_date('2018/03/09','yyyy/mm/dd') 
 and c.date >= all(select date from calendar c2 where c.date = c2.date)

如何将以上查询用作子查询，并将in子句作为参数传递给以下查询？

select * from (

/*above query inside and iterate over in param*/

)abc where abc.date in (to_date('2018/03/09','yyyy/mm/dd') ,to_date('2018/03/10','yyyy/mm/dd') )

Answer 1

select * 
from calendar c 
where c.date in (to_date('2018/03/09','yyyy/mm/dd') ,to_date('2018/03/10','yyyy/mm/dd') )
 and c.date >= all(select date from calendar c2 where c.date = c2.date)

尝试一下。

Answer 2

我不知道我是否正确理解了你。这就是你想做的吗？

SELECT * FROM (
    SELECT * 
    FROM calendar c 
    WHERE c.d_date= to_date('2018/03/09','yyyy/mm/dd') 
            AND c.d_date >= all(SELECT d_date FROM calendar c2 WHERE c.d_date = c2.d_date)
)abc WHERE abc.d_date IN (to_date('2018/03/09','yyyy/mm/dd') ,to_date('2018/03/10','yyyy/mm/dd') );

我将日期列的名称更改为d_date，因为它是保留字。

Answer 3

对不起，我的意思是使用外部查询对子查询进行参数化，并且能够写出类似目的的东西

select * 
from calendar c 
where c.date >= all(select date from calendar c2 where c.date = c2.date) 
and c.date in (to_date('2018/03/09','yyyy/mm/dd'),to_date('2018/03/10','yyyy/mm/dd') )

子查询的IN子句参数
