今天写了一个游标，但是不知道怎么在这游标里定义一个变量来记录执行时影响条数，并插入两条数据时就跳出循环结束游标。
没有想出辙，实属头疼。附代码如下：
--游标
declare @userID uniqueidentifier--userid
declare y_curr cursor for
select top 2 userID from Hope_Users_db.dbo.u_Users order by addTime desc
open y_curr --打开游标
fetch next from y_curr into @userID ----开始循环游标变量
while(@@fetch_status=0)---返回被FETCH 语句执行的最后游标的状态，而不是任何当前被连接打开的游标的状态。
begin
if exists (select * from Q_enterprise where userID = @userID)
begin
print @userID
end
else
begin
print @userID
insert into Q_enterprise
select distinct u.userID, u.userType,u.SyncCharityId as CharityId,u.userTrueName,u.userLogo,0 as donationAmount,e.enterpriseContactMobile,
e.enterprisePurpose,0 as enterpriseLongitude,0 as enterpriseLatitude,'' as Infoproportion,0 as sharesum,0 as praisesum,
0 as Donationsum,0 as Farvritessum,0 as Donationsum30,u.addTime,'' as updatetime
from Hope_Users_db.dbo.u_Users u
inner join Hope_Donation_DB.dbo.d_Donation d
on u.userID=d.userID
inner join Hope_Users_db.dbo.u_Enterprise e
on u.userID = e.userID
where u.userID=@userID
end
fetch next from y_curr into @userID --开始循环游标变量
end
close y_curr--关闭游标
deallocate y_curr --释放游标
go
