运行3层T-SQL查询报告

Question

第一个问题在这里，所以请原谅任何错误......

我想写一个SQL查询的SSRS报告，我完全糊涂了，当涉及到我的连接。

背景：我有3个表是相关

• 出版商 - 这本质上是人的名单
• 发布报告 - 这是一个记录列表（与出版商表）详细介绍了他们在一个月内完成的工作。
• 投诉月份 - 这是与特定月份和年份相关的记录列表（与发布商报告表格有关）。在这些记录中，他们有一个指标，显示它们是否与前六个月期间相关。

我想要做的是获取未提交与过去6个月内的报告月记录相关的发布商报告的发布商列表。我期望的输出是列出的发布者列表，其中列出了他们在下一列中缺失的报告月份。

我真的很挣扎该怎么办呢？我原以为它看作是一个三个步骤的过程......

--step 1 - 获取的包括在过去6个月中报告清单月

WITH ACTIVE6MREPM AS 
(
SELECT   r.jajw_name, 
       r.jajw_CalendarDate 
FROM   jajw_reportmonthBase r 
WHERE   r.jajw_IncludedIn6MonthReport = '1' 
), 

--STEP 2 - Get list of all publishers 
ACTIVEPUBS AS 
(
SELECT   c.FullName, 
       c.ContactId 
FROM   ContactBase c 
WHERE   c.statecode = '0' 
AND    c.jajw_CongregationAssignment != 640840001 
AND    c.jajw_CongregationAssignment != 640840006 
AND    c.jajw_CongregationAssignment != 640840005 
--AND    q.jajw_FieldServiceGroups = (@Field_Service_Group) 
), 

--STEP 3 - Get List of Publisher Reports for the selected Report Months 
RELEVANTREPORTS AS 
(
SELECT   r.jajw_reportId AS Publisher_Report_GUID, 
       r.jajw_PublisherId AS Publisher_GUID, 
       r.jajw_ReportMonthId AS ReportMonth_GUID, 
       m.jajw_name AS ReportMonth_Name 
FROM   jajw_reportBase r 
INNER JOIN  jajw_reportmonthBase m ON r.jajw_ReportMonthId = m.jajw_reportmonthId 
WHERE   r.jajw_ReportPeriod6Month = '1' 
ORDER BY  m.jajw_CalendarDate 

这三个之后，我想创建我的列表，如上所述，这是我难倒了！任何帮助将不胜感激！

谢谢！

我认为你可以缩短你的代码很多......这里有一个镜头，它没有测试数据......一定要阅读注释并添加连接条件并检查where子句。

with cte as(
SELECT   r.jajw_reportId AS Publisher_Report_GUID, 
       r.jajw_PublisherId AS Publisher_GUID, 
       r.jajw_ReportMonthId AS ReportMonth_GUID, 
       m.jajw_name AS ReportMonth_Name, 
       c.FullName, 
       c.ContactId 
FROM   jajw_reportBase r 
INNER JOIN  jajw_reportmonthBase m ON 
       r.jajw_ReportMonthId = m.jajw_reportmonthId 
INNER JOIN  ContactBase c on       --what ever condition is appropiate 
WHERE   r.jajw_ReportPeriod6Month = '1' 
       and m.jajw_IncludedIn6MonthReport = '1' --maybe put this here, or does the above do the same thing? 
ORDER BY  m.jajw_CalendarDate) 

select 
    p2.FullName, 
    p2.ReportMonth_Name 
from cte p 
right join(select distinct 
       ReportMonth_Name, FullName 
      from ContactBase 
      left join jajw_reportmonthBase on 1=1) p2 on p2.FullName = p.FullName and p2.ReportMonth_Name = p.ReportMonth_Name 
where 
    ContactId in (select ContactId from cte group by ContactId having count(distinct ReportMonth_GUID) < 6) 
    and p.FullName is null 

这里是一个使用测试数据的例子。

declare @pub table (pubname varchar(56), ReportMonthName varchar(16)) 
insert into @pub (pubname,ReportMonthName) values 
('a','Jan'), 
('a','Feb'), 
('a','Mar'), 
('a','Apr'), 
--publisher a is missing May and Jun 
('b','Jan'), 
('b','Feb'), 
('b','Mar'), 
('b','Jun') 
--publisher b is missing Apr and May 

declare @dt table (ReportMonthName varchar(16)) 
insert into @dt (ReportMonthName) values 
('Jan'), 
('Feb'), 
('Mar'), 
('Apr'), 
('May'), 
('Jun') 



select 
    p2.pubname 
    ,p2.ReportMonthName 
from @pub p 
right join(
select distinct 
    p.pubname 
    ,d.ReportMonthName 
from @pub p 
left join @dt d on 1=1)p2 on p2.pubname = p.pubname and p2.ReportMonthName = p.ReportMonthName where p.pubname is null
