                  from iaptd where po_id in(Select distinct po_id 
                                            from irct 
                                            where verify_dtim = Date()-1))

Answer 1

我想您只需要更改

Date() - 1

到

DATEADD(dd, -1, CAST(GETDATE() AS DATE))

Answer 2

从GETDATE()（今天）开始减去一天。

Select * 
from iapt 
where appt_id in (Select distinct appt_id 
from iaptd where po_id in(Select distinct po_id 
from irct 
where verify_dtim = DATEADD(day, -1, convert(date, GETDATE())))
