“我正在设置查询，该查询每天选择24小时间隔。我该怎么办？

我搜索了它，然后尝试了一下，但是它只选择了一天的数据。

查询涉及很多复杂性。我绝对会说您应该使用PIVOT。

我已经添加了一些丢失的joins，已使用的PIVOT和我试图删除的不必要的代码。

以下是最适合您的查询：（请注意内联注释以进行描述）

答案 1 :(得分：1)

仅使用条件聚合。我想这就是你想要的：

select trunc(cd.call_time),
       sum(case when extract(hour from cd.call_time) = 8 and
                     cd.call_type in ('001', '002', '003') then 1 else 0
                end) as t08,
       sum(case when extract(hour from cd.call_time) = 9 and cd.call_type in ('001', '002', '003')
                then 1 else 0
           end) as t09,
         . . .
from CALL_DATA cd join
     CALL_DATA_TYPE cdt  
     on cdt.id = cd.call_id  
where cd.CALL_TIME >= to_date(:i_call_time_start, 'YYYYMMDDHH24MISS') and
      cd.CALL_TIME < TO_DATE(:i_call_time_end, 'YYYYMMDDHH24MISS') and
     (:i_checkfalse = 'ALL' or D.CHECK_FALSE_CALL = :i_checkfalse)
group by trunc(cd.call_time);

注意：

  • 学习使用正确的，明确的，标准 JOIN语法。
  • 通话时间具有时间成分，因此您需要提取日期。
  • 条件逻辑的标准SQL语法为CASE。 DECODE()是定制的Oracle逻辑。
  • 将DECODE()用于IN很难。
  • 我认为CALL_DATA_TYPE表不是必需的，但是我已经把它留在里面了。
