如何选择where = list

Question

select NameCompany from [ParticipateFairList] 
where IdFair=(select Id from [TmpFair] where Parent_FK=88)

这是正确的吗？

如何

For Select * From [Table] where ID=`List` or `SubQuery`

Answer 1

select NameCompany from [ParticipateFairList] 
where IdFair in (select Id from [TmpFair] where Parent_FK=88)

其中IdFair在（...）而不是IdFair =（...）

Answer 2

对于MySQL或SQL Server，您需要expr IN (list | subquery)。
