Sql 获取下一个大于值的日期时间

从表中获取同一类型的下一个可用时间，该时间大于该类型的可用拾取时间。我尝试使用第一个值函数，但似乎效果不好

DROP TABLE IF EXISTS Test1;
CREATE TEMPORARY TABLE Test1
(
    Type        VARCHAR(50),
    Pickup_Time TIMESTAMP,
    INSERT_TIME      TIMESTAMP
);
DROP TABLE IF EXISTS Test2;
CREATE TEMPORARY TABLE Test2
(
    Type VARCHAR(50),
    TIMEFRAME  TIMESTAMP
);


INSERT INTO Test1
VALUES ('MAN', '2020-11-01 09:00:00.000000', '2020-11-01 06:00:00.000000');
INSERT INTO Test1
VALUES ('CAT', '2020-11-02 11:00:00.000000', '2020-11-02 05:00:00.000000');


INSERT INTO Test2
VALUES ('MAN', '2020-11-01 01:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 02:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 03:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 04:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 05:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 06:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 07:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 08:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 09:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 10:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 11:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 12:00:00.000000');
INSERT INTO Test2
VALUES ('MAN', '2020-11-01 13:00:00.000000');


INSERT INTO Test2
VALUES ('CAT', '2020-11-01 01:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-01 02:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-01 03:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-01 04:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-01 05:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-02 06:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-02 07:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-02 08:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-02 09:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-02 10:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-02 11:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-02 12:00:00.000000');
INSERT INTO Test2
VALUES ('CAT', '2020-11-02 13:00:00.000000');


SELECT DISTINCT TT.*,
                FIRST_VALUE(CT.TIMEFRAME)
                OVER (PARTITION BY TT.Type ORDER BY TIMEFRAME rows between unbounded preceding and unbounded following)
FROM Test1 TT
         INNER JOIN Test2 CT on TT.Type = CT.Type
    AND TT.Pickup_Time < CT.TIMEFRAME;

但是，当我用不同的时间为类型MAN执行另一次插入并尝试运行相同的SQL语句时，它不符合我的条件

INSERT INTO Test1
VALUES ('MAN', '2020-11-01 03:00:00.000000', '2020-11-01 01:00:00.000000');

对于上述第二个人工输入，该值应为2020-11-01 10:00:00.000000，而不是2020-11-01 04:00:00.000000

如果是，这里使用的第一个值是正确的选项吗？如果是，如何导出逻辑，或者哪一个是可以用来实现这一点的最佳函数。

发生错误的原因是，对于

MAN

有两个条目，但您只需按

类型划分，因此两个条目的处理方式相同，您需要按
拾取时间
或
插入时间
进行分区：

FIRST_值（连续时间）
OVER（按TT.Type划分，按TT.picku时间顺序划分，按无界前后行之间的时间帧行划分）

这将产生：


type    pickup_time insert_time first_value
MAN 2020-11-01 03:00:00 2020-11-01 01:00:00 2020-11-01 04:00:00
CAT 2020-11-02 11:00:00 2020-11-02 05:00:00 2020-11-02 12:00:00
MAN 2020-11-01 09:00:00 2020-11-01 06:00:00 2020-11-01 10:00:00

非常感谢Philipp，很抱歉延迟了响应，我正在用我的数据集测试它，它工作得非常好
