Question

我写了一个程序如下

USE [Farm_Project]
GO
/****** Object:  StoredProcedure [dbo].[prod1_insert]    Script Date: 11/12/2014 1:21:20 PM      ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER proc [dbo].[prod1_insert]
(
  @coop_id int,
  @good_eggs int=0,
  @broken_eggs int=0,
  @small_eggs int= 0,
  @date smalldatetime=null

  )
  AS
  if @date is null
  set @date=getdate()

  insert into Prod1 (cc_id,  gd_Eggs,   br_Eggs,   sm_Eggs,  Prod_date  )
  values
                  (@coop_id  ,@good_eggs,  @broken_eggs, @small_eggs,@date)

然后我将该过程用作ASPX Gridview的插入查询（DEV Express）

我也有类似的插入程序。

但是在这两种情况下，我输入的所有值都被传递为Null并且我得到一个错误＆＃34;无法为列CC_ID＆＃34;插入Null，并且通过使用SQL Server Pofiler我发现所有值都被发送到SQL服务器为＆＃39; null＆＃39;。请帮助我尝试了所有我知道的事情。

提前谢谢。
