Question

我有以下

delete from Listing
where not exists
(
   select 1
   from ComparitiveListings
   where Listing.ListingKey = ComparitiveListings.ListingKey
 )

但我真正想做的是为表MySproc中ListingKey的每个LISTING执行一个存储过程COMPARITIVELISTINGS，该存储过程在列ListingKey列中找不到{1}}。

我认为必须有光标的方法，但我不确定？有人在这吗？

Answer 1

Create proc myProc
As
BEGIN
delete from Listing
    where ListingKey not in
    (
       select ListingKey
       from ComparitiveListings

     )
END

为不存在的每个项调用存储过程
