Sql 加入范围内的最大日期

我有两张表格：部门交易和深度历史

SELECT *
  FROM deal
       LEFT JOIN depth
         ON (    deal.dept_gid = depth_gid
             AND deal.deal_begin_date <= depth_end_date
             AND deal.deal_end_date >= depth_start_date)

---

但若深度中有多行满足相同dept\u gid和范围必须相交的条件，那个么我需要返回具有最大深度\u end\u日期的行。如何操作？

尝试在此处使用行号：

SELECT *
FROM
(
    SELECT d1.*, d2.*,
        ROW_NUMBER() OVER (PARTITION BY d1.dept_gid ORDER BY d2.depth_end_date DESC) rn
    FROM deal d1
    LEFT JOIN depth d2
        ON d1.dept_gid = d2.depth_gid AND
           d1.deal_begin_date <= d2.depth_end_date AND
           d1.deal_end_date >= d2.depth_start_date
) t
WHERE rn = 1

你能提供一些样本数据和预期结果吗？这真的很有帮助。你能提供一些样本数据和预期结果吗？这真的很有帮助谢谢，我刚刚更改了分区，移动了这个join in WITH子句，然后添加了其他连接谢谢，我刚刚更改了分区，移动了这个join WITH子句，然后添加了其他连接
