oracle - 查询最接近查询的上一个日期

Question

表记录：

process date total
------------ -----
31/12/2018     433  
30/09/2018     433  
09/07/2018    1873  

查询日期时：09/07/2018
结果是：

process date total
------------ -----
09/07/2018    1873  

查询日期时：30/09/2018
结果是：

process date total
------------ -----
30/09/2018     433

查询日期时：10/08/2018
结果是：

process date total  
------------ -----
09/07/2018    1873 

它应该带来的是：

process date total  
------------ -----
30/09/2018     433 

正确的结果应该是09/07/2018

如果您删除ABS未来的日期将是积极的；所以我认为您可以将它们过滤掉：

...
              RANK() OVER ( ORDER BY DIFERENCIA ) AS ROWNUMBER
          FROM (
              SELECT 
                  -- remove the ABS() call
                  -- ABS(PREDET.DTE_FECPRO - TO_DATE('30/09/2018', 'DD/MM/YY')) AS DIFERENCIA,
                  PREDET.DTE_FECPRO - TO_DATE('30/09/2018', 'DD/MM/YY') AS DIFERENCIA,

                  )                  
                  -- add a filter
                  WHERE DIFERENCIA <= 0
                )
                WHERE ROWNUMBER = 1 GROUP BY CHR_SECECO,VC_SECECO
...

我保留了您的原始格式；如果您正确缩进，将更容易看到发生了什么。我已经包含了对这两个更改的评论。显然我没有你的表格或数据未经测试......
