Question

我有以下代码，它通过将参数与表中的主键匹配来触发存储过程来删除记录。我通过调试运行代码一切都正确分配，但我一直收到一个错误，指出有太多的参数指定。我认为它与我的存储过程有关，因为正确分配了值。

    Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
    Dim CurrentCommand As String = e.CommandName
    Dim CurrentRow As Integer = Int32.Parse(e.CommandArgument.ToString())
    Dim ID As String = GridView1.DataKeys(CurrentRow).Value

    sqlds.DeleteParameters.Add("KeyOpType", ID)
    sqlds.Delete()


End Sub

SQL Server 2008中的存储过程

ALTER PROCEDURE [dbo].[GetGenInfo_DeleteMines]
(@KeyOpType int)
AS
Delete FROM GenInfo_OpType
Where KeyOpType = @KeyOpType

Answer 1

您在哪里设置删除命令？我们是否确定它正在调用正确的程序？我想这就是你要做的。检查一下：

SQLDataSource with GridView and CRUD

Answer 2

不确定这是否能解决问题......但是

您似乎缺少存储过程中的BEGIN。我是新手，但我认为这是必需的。

ALTER PROCEDURE [dbo].[GetGenInfo_DeleteMines]
(@KeyOpType int)
AS
BEGIN <-----------------------------------MISSING THIS
Delete FROM GenInfo_OpType
Where KeyOpType = @KeyOpType

另外，我没有看到你在vb代码中调用SP的位置。

编辑：提供进一步的例子......

我在gv Row Command上的代码看起来像这样......（如果它来自gv上的按钮/链接，必须将CommandName =“SomeCommandName”添加到gv上的控件上）

    Protected Sub gvName_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvName.RowCommand

        Dim tGrid As GridView = DirectCast(sender, GridView)
        Dim tIndex As Integer = Convert.ToInt32(e.CommandArgument)
        Dim row As GridViewRow = Nothing

Select Case e.CommandName
            Case "SomeCommandName"
                CallToDelete(tGrid.DataKeys(tIndex).Value)
        End Select

    End Sub

存储过程中的参数太多错误
