游标 处女作

　　由于触发器的原因，所以更新数据的时候经常不能使用直接update来修复数据。所以试着去用游标来更新

declare upduser scroll cursor
for
select aopp_userid from aopportunity
where aopp_userid <> aopp_createdby 
and aopp_status ='ccfollowup' 
and aopp_deleted is null
and aopp_userid is not null
for update

open upduser

declare @aopp_userid int
fetch from upduser into @aopp_userid
while @@fetch_status = 0
    begin
        if @aopp_userid is not null
        --print @aopp_userid
        update aopportunity set aopp_createdby = @aopp_userid,aopp_contractcounselor = @aopp_userid 
        where current of upduser
        fetch from upduser into @aopp_userid
    end
close upduser
deallocate upduser
