我有一张数据表,

    ID        SEQ    EFFDAT                 
------- ---------    -----------------------
  1024          1    01/07/2010 12:00:00 AM   
  1024          3    18/04/2017 12:00:00 AM   
  1024          2    01/08/2017 12:00:00 AM   

当我执行以下查询时,我得到错误的最大序列仍然得到正确的最大生效日期.

查询:

SELECT 
max(seq) over (partition by id order by EFFDAT desc) maxEffSeq,
partitionByTest.*,
max(EFFDAT) over (partition by (id) order by EFFDAT desc ) maxeffdat
FROM partitionByTest;

输出:

 MAXEFFSEQ         ID        SEQ EFFDAT                   MAXEFFDAT              
---------- ---------- ---------- ------------------------ ------------------------
