此处的人格是该人的身份。 Trailid是我们正在查看的id，orgid是组织的id，orgtypeid是组织的类型。
现在我们想要的是每组trialid（这个例子只有一个trailid，但基表有多个trialid），我想创建6个新变量，如下所示：
Non Academic_fraction_orgs Academic_frac_orgs Others_frac_orgs Non Academic_fraction_ppl Academic_frac_ppl Others_frac_ppl
orgtypeid：9,18,3被分类为学术，而4,22,17被分组为非学术，而剩余被分组为其他。现在我们需要以下变量和以下值：
Non Academic_fraction_orgs: Total orgids in Non-Academic in that trialid/Total Orgids in that trialid
Academic_fraction_orgs: Total orgids in Academic in that trialid/Total Orgids in that trailed
Others_frac_orgs: Total orgids in Other in that trialid/Total Orgids in that trailed
Non Academic_fraction_ppl: Total distinct Personid in Non-Academic in that trialid/Total Orgids in that trailed
Academic_fraction_ppl: Total distinct Personid in Academic in that trialid/Total Orgids in that trailed
依旧......
如何在sql中完成此操作。
编辑：
strorganizationtype是各自orgtypeid的字符串。
select trialid, count(CASE WHEN strorganizationtype in ('Academic Institution - office','Academic Institution - research facility',
'Academic Hospital / Clinic')
THEN 1 ELSE 0 END) /(count(*)*1.0) as Academic_frac_orgs,
count(CASE WHEN strorganizationtype in ('Medical Practice','Clinical Trial Center',
'Rehabilitation/Extended Care Facility','Non-academic Hospital / Clinic')
THEN 1 Else 0 END)/(count(*)*1.0) as Non_Academic_fraction_orgs,
count(CASE WHEN strorganizationtype in ('Company','Other')
THEN 1 ELSE 0 END)/(count(*)*1.0) as Other_fraction_orgs
from table
group by trailid
order by trialid
问题在于计算（例如，＆＃39;公司＆＃39;，＆＃39;其他＆＃39;中的strorganizationtype） 那么1 ELSE 0 END）计算该试验的所有记录，而不是属于该特定案例陈述的记录。我需要一个变量，它是属于该组orgs的记录的一小部分，属于该组的总组织。
