如何为该表构建子查询？

Question

I have a table that will always have a row for the en-US culture. I am trying to write a query that will give me results for rows that do not also contain es or fr-CA. Could anyone point me in the right direction?

TextKey	Culture
DutyType.SigningCeremonyOnly	en-US
DutyType.SigningCeremonyOnly	es
DutyType.SubmitOnly	es
DutyType.SubmitOnly	en-US
DutyType.SubmitOnly	fr-CA

Answer 1

You seem to be asking for:

select t.*
from t
where not exists (select 1
                  from t t2
                  where t2.textkey = t.textkey and t2.culture in ('es', 'fr-CA')
                 );

I'm not sure why it is relevant that rows exist for en-US .
