Question

这是我的代码。谁能告诉我哪些或哪里不正确？我花了3天多的时间试图找出它并且没有看到它，我的报告将在下周发布。

SELECT
   t1.IT1 as "Issue Type",
   t1.sum(REC) as "Total Received",
   t2.sum(RES) as "Total Resolved",
   t1.Count(project_key) as REC,
   t2.Count(project_key) as RES
FROM
   (select
    IT1 as "Issue Type",
    sum(REC) as "Total Received"
    FROM
       (case
        when issue_type = 'MIS Sub-task' then 'MIS'
        when issue_type = 'Reporting Sub-task' then 'Reporting'
        when issue_type = 'NICE Analytics Sub-task' then 'NICE Analytics'
        when issue_type = 'Demand Mitigation Sub-task' then 'Demand Mitigation'
        else issue_type
        end as IT1,
Count(project_key) as REC
FROM jira17.FCI4JIRA_common_view 
WHERE issue_type in ('MIS', 'MIS Sub-task', 'Reporting', 'Reporting Sub-Task', 'NICE Analytics', 'NICE Analytics Sub-Task', 'Demand Mitigation', 'Demand Mitigation Sub-Task') and 
status not like 'Cancelled' and 
date_created between to_date ('01/12/2013', 'dd/mm/yyyy') and to_date ('01/01/2014', 'dd/mm/yyyy') group by issue_type)  group by IT1) t1

inner join t2 on t1.IT1 = t2.IT2

  (select 
    IT2 as "Issue Type",
    sum(RES) as "Total Resolved"
    FROM
       (case
        when issue_type = 'MIS Sub-task' then 'MIS'
        when issue_type = 'Reporting Sub-task' then 'Reporting'
        when issue_type = 'NICE Analytics Sub-task' then 'NICE Analytics'
        when issue_type = 'Demand Mitigation Sub-task' then 'Demand Mitigation'
        else issue_type
        end as IT2,
Count(project_key) as RES
from jira17.FCI4JIRA_common_view

这是一个非常复杂的SQL句子。因为这个，你的问题是不可读的。社区无法花时间调试您的查询。你应该能够自己做。我建议你“划分和统治”，因为这样，你应该了解CTE的表达方式。使用CTE，您可以以更易读的方式组织查询。

对于你的句子：

With T11 as (
 select
      case
            when issue_type = 'MIS Sub-task' then 'MIS'
            when issue_type = 'Reporting Sub-task' then 'Reporting'
            when issue_type = 'NICE Analytics Sub-task' then 'NICE Analytics'
            when issue_type = 'Dema...gation Sub-task' then 'Demand Mitigation'
            else issue_type
            end as IT1,
      Count(project_key) as REC
 FROM 
      jira17.FCI4JIRA_common_view 
 WHERE issue_type in ('MIS', 'MIS Sub-task', 'Reporting', ...) and 
          status not like 'Cancelled' and 
          date_created between to_date ('01/12/2013', 'dd/mm/yyyy') 
          and to_date ('01/01/2014', 'dd/mm/yyyy') 
 GROUP BY issue_type ),
T1 as (
 SELECT
    t1.IT1 as "Issue Type",
    t1.sum(REC) as "Total Received",
    t2.sum(RES) as "Total Resolved",
    t1.Count(project_key) as REC,
    t2.Count(project_key) as RES
FROM
    FROM T11
    group by IT1 ),
-- and so on ...
