我有一个网站，其中一个表格将显示资产列表及其从 sql 表格中提取的信息。我有一个部分按钮，如有必要，职员可以通过在文本或下拉字段中输入新信息来按下和修改现有信息。这是使用存储过程完成的；在您检查工作之前，一切似乎都运行良好，没有任何更新！

这是编辑信息的代码；

    protected void ADD_Click(object sender, EventArgs e)
{
    using (SqlConnection connection = new SqlConnection(WebConfigurationManager.ConnectionStrings["DATASYSTEMS"].ConnectionString))
    {
        SqlCommand cmd = new SqlCommand("UPDATING_ASSETS", connection);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@ASSET_NUMBER", Txtasset_number.Text);
        cmd.Parameters.AddWithValue("@MACHINE_NAME", Txtmachine_name.Text);
        cmd.Parameters.AddWithValue("@PORT_NUMBER", Txtport_number.Text);
        cmd.Parameters.AddWithValue("@BUILDING_NUMBER", DPBUILDING.SelectedValue);
        cmd.Parameters.AddWithValue("@ROOM_NUMBER", Txtroom_number.Text);
        cmd.Parameters.AddWithValue("@TELEPHONE_NUMBER", Txttelephone_number.Text);
        cmd.Parameters.AddWithValue("@FLOOR", Txtfloor.Text);
        cmd.Parameters.AddWithValue("@SERIAL", Txtserial.Text);
        cmd.Parameters.AddWithValue("@TYPE", DPTYPE.SelectedValue);
        cmd.Parameters.AddWithValue("@BRANCH", DPBRANCH.SelectedValue);
        cmd.Parameters.AddWithValue("@SECTION", DPSECTION.SelectedValue);
        cmd.Parameters.AddWithValue("@USERS", txtuser1.Text);
        ClientScript.RegisterClientScriptBlock(this.GetType(), "key", "<script type='text/javascript'>alert('Record has been updated.');window.location='navigation.aspx';</script>");
    }
}
protected void dglocaltables_SelectedIndexChanged(object sender, EventArgs e)
{

}

}

这是应该更新的存储过程。

    CREATE PROCEDURE [dbo].[update_TBL_INFO_1] @ASSET_NUMBER as nvarchar(50), @PORT_NUMBER as nvarchar(50), @MACHINE_NAME as nvarchar(50), @TYPE as nvarchar(50) ,  @BRANCH as nvarchar(50), @SECTION as nvarchar(50), @BUILDING_NUMBER as nvarchar(50), @ROOM_NUMBER as nvarchar(50), @TELEPHONE_NUMBER as nvarchar (50), @FLOOR as nvarchar (50), @USERS as nvarchar (50), @ID as float (8), @SERIAL as nvarchar (50) as

If (SELECT ASSET_NUMBER FROM dbo.TBL_INFO WHERE ASSET_NUMBER=@ASSET_NUMBER AND [ID]=@ID)=@ASSET_NUMBER
BEGIN
    If (SELECT MACHINE_NAME FROM dbo.TBL_INFO WHERE MACHINE_NAME=@MACHINE_NAME AND [ID]=@ID)=@MACHINE_NAME
    BEGIN
        If (SELECT PORT_NUMBER FROM dbo.TBL_INFO WHERE PORT_NUMBER=@PORT_NUMBER AND [ID]=@ID)=@PORT_NUMBER
        BEGIN
            If (SELECT [ID] FROM dbo.TBL_INFO WHERE [ID]=@ID)=@ID
            BEGIN

                UPDATE dbo.TBL_INFO
                    SET
                    dbo.TBL_INFO.ASSET_NUMBER = @ASSET_NUMBER,
                        dbo.TBL_INFO.MACHINE_NAME = @MACHINE_NAME,
                        dbo.TBL_INFO.PORT_NUMBER = @PORT_NUMBER,
                        dbo.TBL_INFO.BUILDING_NUMBER = @BUILDING_NUMBER,
                        dbo.TBL_INFO.ROOM_NUMBER = @ROOM_NUMBER,
                        dbo.TBL_INFO.TELEPHONE_NUMBER = @TELEPHONE_NUMBER,
                        dbo.TBL_INFO.[FLOOR]= @FLOOR,
                        dbo.TBL_INFO.TYPE = @TYPE,
                        dbo.TBL_INFO.BRANCH = @BRANCH,
                    dbo.TBL_INFO.[SECTION] = @SECTION,
                        dbo.TBL_INFO.USERS = @USERS,
                    dbo.TBL_INFO.[ID] = @ID,
                    dbo.TBL_INFO.SERIAL = @SERIAL
                                WHERE dbo.TBL_INFO.ASSET_NUMBER=@ASSET_NUMBER
                INSERT INTO dbo.TBL_INFO (ASSET_NUMBER, MACHINE_NAME, PORT_NUMBER, BUILDING_NUMBER, ROOM_NUMBER, TELEPHONE_NUMBER, [FLOOR], TYPE, BRANCH, [SECTION], USERS, SERIAL, [ID]) VALUES (@ASSET_NUMBER, @MACHINE_NAME, @PORT_NUMBER, @BUILDING_NUMBER, @ROOM_NUMBER, @TELEPHONE_NUMBER, @FLOOR, @TYPE, @BRANCH, @SECTION, @USERS, @SERIAL, @ID) 
                SELECT @ID, ACCESS='VALID'

            END

                 ELSE   
                BEGIN
                    SELECT @ID, ACCESS='INVALID'
                END
        END

    ELSE
        BEGIN
            SELECT ACCESS='RESTRICTED'
        END
    END
ELSE
    BEGIN
        SELECT ACCESS='DENIED'      
    END
END

去

我哪里错了？

你永远不会执行命令！

您需要在所有这些 .AddWithValue() 调用结束时使用它：

cmd.ExecuteNonQuery();
