delete from PSD

from PurchaseStationeryDetails PSD
where not exists ( 
                  select 1 from  @TVP_PurchaseStationeryDetails TVP_PSD
                  where PSD.PurchaseStationeryMasterId = TVP_PSD.PurchaseStationeryMasterId
                  and isnull(PSD.PurchaseStationeryDetailsId,0)  = TVP_PSD.PurchaseStationeryDetailsId

and PSD.PurchaseStationeryMasterId = 1003 

Answer 2

尝试使用Left或Right Outer Join

 create table #tvp (id int, val int)

insert into #tvp 
values
(101, 1), (102,  2),(103,2)

create table #purchase (iden int, value int)

insert into #purchase 
values
(101, 1), (102,  2),(103,2),(104,2)


delete p
from #tvp t
right outer join
#purchase p 
on (t.val = p.value and t.id = p.iden)
where t.id is null
