嘿我有多个BannerID，我需要存储过程中的参数我想循环存储过程，更改作为参数传递的BannerID。这是我的代码，
create table #a
(BannerID int,
BannerName varchar(100)NULL,
InterActionRate Decimal(5,3) NULL
)
Declare @Banker int
Set @Banker = 0
insert into #a(BannerID)
Values (21212),(21577)
WHILE (@Banker > 2)
BEGIN
Insert Into #a(BannerName,InteractionRate)
Exec BannerSummaryReport @BannerID=BannerID,@DateStart = N'05/01/15',@DateEnd = N'05/20/15'
Set @Banker = @Banker +1
END
Select * from #a
我一直收到错误：
消息8114，级别16，状态5，过程BannerSummaryReport，第0行 将数据类型nvarchar转换为int时出错。错误循环，好像它被调用了两次以上，我永远不会执行查询。如果有帮助。任何想法？
编辑：我添加了一个名为@Banker的变量，我将其用作while循环的计数器。这使得循环现在结束了。但是我的存储过程仍然没有填充数据，IE BannerName和InteractionRate在表中仍为空。
有些人已经请求存储过程问题是我无法访问它我可以给你一个输出的例子，
Exec BannerSummaryReport @ BannerID = 21212，@ DateStart = N'05 / 01/15'，@ DateEnd = N'05 / 20/15'

答案 0 :(得分：1)
很明显，您的代码中存在错误。我可以重现错误：
create procedure spTest @i int
as
Select @i as i
go
exec spTest @i = blabla
错误：
将数据类型nvarchar转换为int时出错。
现在看看你的代码：
Exec BannerSummaryReport @BannerID=BannerID,@DateStart = N'05/01/15',@DateEnd = N'05/20/15'
什么是@BannerID=BannerID？您没有将int值传递给存储过程的int参数。您正在传递BannerID字样。
修改
我想你想要遍历#a表中的所有行，并使用从特定行的存储过程返回的数据更新BannerName和InterActionRate列。不幸的是，没有直接的方式。
您需要声明另一个临时表，该表将包含以相同顺序存储proc返回的所有列。即
create table #a
(
BannerID int,
BannerName varchar(100) NULL,
InterActionRate int NULL
)
insert into #a(BannerID)
Values (21212),(21577)
create table #tmp
(
ReportID
BannerName
TagName
CompanyName
BannerStatusID
BannerID
Impressions
FlashImpressions
NoScriptImpressions

)
为这些列提供合适的类型。
然后你需要游标来迭代表#a中的行：
Declare @BannerID int
declare cur cursor fast_forward for
select BannerID from #a
open cur
fetch next from cur into @BannerID
while @@FETCH_STATUS = 0
begin
insert into #tmp
exec spTest @BannerID
fetch next from cur into @BannerID
end
close cur
deallocate cur
最后一步是从#a表更新#tmp表：
update a set BannerName = t.BannerName, InterActionRate = t.InterActionRate
from #a a
join #tmp t on a.BannerID = t.BannerID
现在您已在表#a中更新了数据。
