SP是

 [dbo].[UpdateProdsWithParam] @prodID int, @CatID int, @title nvarchar(50), 
                                            @Sdesc nvarchar(100), @Ldesc nvarchar(200), 
                                            @url nvarchar(50), @price money
AS
UPDATE Product
SET CategoryID = @CatID, Title = @title, 
ShortDescription = @Sdesc, LongDescription = @Ldesc, 
ImageUrl = @url, Price = @price
WHERE ProductID = @prodID

我收到“过程或函数指定的参数太多”

有什么建议吗？

【问题讨论】：

我认为这是更新时发生的，是吗？你能打开 SQL Profiler 看看什么 SQL 被发送到 UpdateProdsWithParam 吗？

【解决方案1】：

分享您的 C# 代码。错误清楚地表明您传递了太多参数。查看您的参数计数和参数名称。
