I'm trying to learn SQL Server 2005 and ASP.NET 2.0. (I've been working with SQL 2000/.NET 1.1 until now.) I can't get past the following problem and hope one of you gurus can help:
The error I'm struggling with is: Procedure or function editArea has too many arguments specified.
NOte that this is a trimmed down version of the actual form page, which gets its ID from a GridView selection. That form also produces other errors, but I'm going to start with this error before tackling those.
The stored procedure follows:
Code:
ALTER PROCEDURE [dbo].[editArea]
[COLOR=green]
(
-- Add the parameters for the stored procedure here
@AreaId int,
@Name varchar(50),
@Description varchar(255) = NULL,
@ParentId int = NULL,
@TypeId tinyint,
@Enabled bit,
@original_Name varchar(50),
@original_Description varchar(255) = NULL,
@original_ParentId int = NULL,
@original_TypeId tinyint,
@original_Enabled bit,
@Error bit OUTPUT,
@Message varchar(255) OUTPUT
)[/color]
AS
BEGIN
[COLOR=red]-- I do a bunch of stuff, mostly checking for valid
-- input and update if valid, set
-- message and error parameters[/color]
[COLOR=green]RETURN [/color]
ENDThe Relevant section of the ASPX Page follows:
