我希望这是您的要求:
SELECT count(DISTINCT name)
FROM TABLE
WHERE cerification='TA'
AND status='certified'
AND name IN
(SELECT DISTINCT name
FROM TABLE
WHERE cerification='STA'
AND status='Enrolled');
祝你好运....如此投票的人,这只是一个初步的答案,可以使人们更好地理解它。不要太快判断。

) t2 on t1.name=t2.name

您可以尝试使用“ FILTER”关键字...
select count(name) filter (where cerification='TA' and status='certified'
and name in (select name from table where cerification='STA' and status='Enrolled')
from table;

将文件加载到Qlikview后,文件被标记为“ qlikview”,因此您可以使用集合分析:
Count(DISTINCT {
< cerification={'STA'}, status={'Enrolled'} > *
< cerification={'TA'}, status={'Enrolled'} >
