选择多个条件MAX

Question

如何选择最多具有多个条件的数据

SELECT * FROM [TEMP_TBL]，其中“ FLDR_NUM” =（从[TEMP_TBL]选择MAX（FLDR_NUM））和“ DNLD_DT” =（从[TEMP_TBL）选择MAX（DNLD_DT）] >>

[如何选择具有多个最大条件的数据SELECT * FROM [TEMP_TBL]，其中“ FLDR_NUM” =（SELECT MAX（FLDR_NUM）来自[TEMP_TBL]）和“ DNLD_DT” =（SELECT MAX（DNLD_DT）来自[TEMP_TBL）

Answer 1

您可以使用cte重用您的max()值。

with cte(maxflr) as (
    select max(fldr_num) as maxflr from TEMP_TBL
)select * from TEMP_TBL 
cross apply cte
where "FLDR_NUM" = cte.maxflr and "DNLD_DT" = cte.maxflr
