oracle 查询以识别一些基于重叠日期期间的条件
oracle query to identify some condition based overlapping date periods
我有一个数据集，其日期在一个缓慢变化的维度 table 中重叠。我正在尝试提出一个查询，以根据少数条件找出具有重叠日期范围的人。
例如
PERSON_ID,RELATION_ID,RELATION_NAME,START_DT, END_DT, ACTIVE_IND,LATEST_ROW
STEVE -1 NONE 7/26/2018 10/24/2018 Y N
STEVE 111 STUDENT 8/8/2018 10/22/2018 Y N
STEVE 111 STUDENT 10/23/2018 12/31/4712 Y Y
STEVE -1 NONE 10/25/2018 2/7/2019 Y N
STEVE 222 Manager 8/9/2018 12/31/4712 Y Y
BOB 333 ASSOCIATE 8/9/2018 12/31/4712 Y Y
BOB 666 TEACHER 8/10/2018 12/31/4712 Y Y
Dave 555 Director 8/9/2018 12/31/4712 Y Y
我想找到具有重叠日期范围的 person_ids，仅当 relationship_id 中至少有一个为 -1 时。例如，BOB 在重叠时期既是同事又是老师。一个人有两个角色是可以的。但是，我想找出所有日期重叠的人，这些人涉及 "None" 关系和其他一些角色。例子：史蒂夫。
你能给我一些关于如何提出查询的建议吗
Oracle 设置:
CREATE TABLE table_name ( PERSON_ID, RELATION_ID, RELATION_NAME, START_DT, END_DT, ACTIVE_IND,LATEST_ROW ) AS
SELECT 'STEVE', -1, 'NONE', DATE '2018-07-26', DATE '2018-10-24', 'Y', 'N' FROM DUAL UNION ALL
SELECT 'STEVE', 111, 'STUDENT', DATE '2018-08-08', DATE '2018-10-22', 'Y', 'N' FROM DUAL UNION ALL
SELECT 'STEVE', 111, 'STUDENT', DATE '2018-10-23', DATE '4712-12-31', 'Y', 'Y' FROM DUAL UNION ALL

SELECT 'Dave', 555, 'Director', DATE '2018-08-09', DATE '4712-12-31', 'Y', 'Y' FROM DUAL;
查询:
SELECT DISTINCT
PERSON_ID
FROM table_name t
WHERE RELATION_ID = -1
AND EXISTS (
SELECT 1
FROM table_name o
WHERE t.person_id = o.person_id
AND t.end_dt > o.start_dt
AND t.start_dt < o.end_dt
AND o.relation_id <> -1
)
输出:
| PERSON_ID |
| :-------- |
| STEVE |

用上面的模式识别拍了一张照片，它显示了所有相互重叠的行。在这种情况下，一行在 RELATION_IDs = -1 中重叠了两次，因此它在两种重叠情况下都显示同一行，并且查询将其标记为 overlap_num 1 和 2.
