Question

我正在举办一场比赛，其中列出了学校老师观看的所有视频，但是如果他们观看的其中一个视频是一个词干，那就是＆＃39;视频，我希望他们的名字被列出两次，以便他们可以两次进入绘图基本上我在那里有一个case when条款，这样如果一个视频中包含“＆＃39; stem＆＃39;在标题中，我的表格的最后一栏是“干”＆＃39;别的＆＃39; 0＆＃39;。在最后一栏说干的情况下，我想重复整行。我希望这是有道理的。这是我到目前为止所拥有的;

SELECT *
FROM (
SELECT District, 
       SchoolName, 
       PersonnelId, 
       Name, 
       EmailAddress, 
       BeganViewingDate, 
       CASE WHEN SecondsCompleted >= SeventyFivePercent 
            THEN ContentName 
            ELSE '0' END as 'ContentName',
       SegmentLengthInSeconds, 
       SecondsCompleted,
       CASE WHEN contentname LIKE '%Stem%' 
            THEN 'Stem' 
            ELSE '0' END As 'Stem'
FROM (

SELECT vp.PersonnelId,
       cp.EmailAddress, 
       CONCAT(cp.LastName, ', ', cp.FirstName) as Name, 
       vp.BeganViewingDate, 
       vp.SecondsCompleted, 
       c.ContentId, 
       c.ContentName, 
       c.SegmentLengthInSeconds, 
       ROUND(SegmentLengthInSeconds*0.75) as SeventyFivePercent,     
       cv.SchoolName, 
       cv.District
FROM PD360v2.ViewingProgress as vp
JOIN PD360v2.Content as c on vp.ContentId = c.ContentId
JOIN PD360v2.ClientPersonnel as cp on vp.PersonnelId = cp.PersonnelId
JOIN PD360v2.ClientView as cv on cp.ClientId = cv.Id
WHERE vp.BeganViewingDate BETWEEN '2016-02-02 08:00:00' AND '2016-02-09 07:59:00'
AND cv.NcesDistrictId IN (List Of districts here)

) as a

ORDER BY PersonnelId) as b
WHERE ContentName not like 0
ORDER BY District, SchoolName, Name;

Answer 1

我只是简要介绍一下sql，你应该添加自己想要的列

Select vp.name,'0' from PD360v2.ViewingProgress as vp
Where vp.BeganViewingDate between '2016-02-02 08:00:00' and '2016-02-09 07:59:00' And cv.NcesDistrictId in (List Of districts here)
Union all
Select vp.name,'Stem' from PD360v2.ViewingProgress as vp
join PD360v2.Content as c on vp.contentid=c.contentid
Where vp.BeganViewingDate between '2016-02-02 08:00:00' and '2016-02-09 07:59:00' And cv.NcesDistrictId in (List Of districts here) and contentname like '%Stem%'
