【问题描述】：
我遇到了问题，但没有抛出任何错误。发生的事情是我有一个存储过程正在驱动我的更新，但我无法让 gridview 更新。
我点击了Update 链接按钮，但它实际上并没有更新记录。
这是我的存储过程：
ALTER PROCEDURE [dbo].[CompDev_Update](
@CompID int,
@NewDevCount nchar(10) = null,
@DevelopmentName nvarchar(255) = null,
@City nvarchar(255) = null,
@State nvarchar(255) = null,
@ZipCodeofNewDev nchar(10) = null,
@ProjectStatus nvarchar(255) = null,
@ShoppingCenter nvarchar(255) = null,
@ProjectStartDate float = null,
@ProjectDescription nvarchar(255) = null,

我做错了什么导致更新不会发生？为什么当它不更新时我没有收到任何错误？
【问题讨论】：
-
旁注：您应该不为您的存储过程使用
sp_前缀。微软有reserved that prefix for its own use (see Naming Stored Procedures)，你确实会在未来某个时候冒着名称冲突的风险。 It's also bad for your stored procedure performance。最好只是简单地避免sp_并使用其他东西作为前缀 - 或者根本没有前缀！ -
另外，我发现那些“全能”存储过程——虽然很诱人——到头来却非常危险。您只有一个凌乱的程序，每次发生任何变化时都需要对其进行更改....为什么不只使用 四个 单独的集中程序 - 一个到
SELECT，一个到INSERT，一个到UPDATE，最后一个到DELETE（如果需要的话）。想想单一职责原则 - 每段代码都应该做好一件事，并且只做一件事。现在，您传入太多参数只是为了删除一些东西...... -
好的，我分离了我的存储过程，但更新仍然无法在 Gridview 上运行。我的存储过程现在称为 CompDev_Update，我所做的只是改变了这个 ALTER PROCEDURE [dbo].[CompDev_Update](@CompID int，我的更新查询仍然是一样的。我在这里做错了什么？
