Sql oracle如何从其他表中获取列值

我有以下表格和一些列：

我想要的逻辑有点复杂，但我试图找到一种方法，在以下查询中引用baar_value-where子句中表foo中的reportdate：

SELECT *
FROM foo
WHERE baar IS NOT NULL
AND NOT EXISTS
  (SELECT *
  FROM baar_value
  WHERE b_value = baar
  AND reportdate
  BETWEEN from_date AND to_date
  )

---

如何检查foo.reportdate是否介于baar_值。from_日期和baar_值\u to_日期之间？

根据您的描述，您可能只需要以下内容：

SELECT *
FROM foo
WHERE baar IS NOT NULL
AND NOT EXISTS
  (SELECT *
  FROM baar_value
  WHERE b_value = baar
    AND foo.reportdate BETWEEN from_date AND to_date
  )

测试：

SQL> create table foo(reportdate, baar) as
  2      select date '2016-04-01', 1 from dual;

Table created.

SQL> create table baar_value( b_value, from_date, to_date) as
  2      select 1, date '2016-01-01', date '2017-01-01' from dual union all
  3      select 1, date '2015-01-01', date '2016-01-01' from dual;

Table created.

SQL> SELECT *
  2  FROM foo
  3  WHERE baar IS NOT NULL
  4  AND NOT EXISTS
  5                (SELECT *
  6                FROM baar_value
  7                WHERE b_value = baar
  8                  AND foo.reportdate BETWEEN from_date AND to_date
  9                );
