Question

我正在尝试在vb 2010中开发一个实用程序，它会将Datagridview控件的值存储到mysql表中

步骤 1）Datagrid单元格值存储在数组中 2）使用数组值.AddWithValue（）函数

现状：仅插入空白记录。数据丢失。

请参阅以下代码。

我在C＃编写了一个代码，我必须将数据从数据网格存储到SQL数据库。我使用了以下代码。我认为它会对你有帮助。

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>

Answer 2

好笑，我把字段名前缀@更改为？事情变得顺利了。在2月11日早些时候的一个问题中，Stelian Matei提出了这个编辑，尽管稍后Giezel Esteves推翻了它。（2月10日用户1176607提出原始问题）

我想我需要更彻底地参考文档。无论如何，如果您或任何对此感兴趣的人，我会在这里提供工作代码。

        Dim qry As String = "INSERT INTO dyn_dwg_register (`file_name` , `file_location`, `dwg_description`, `project_id`, `created_by`)" & _
                                  " values (?file_name, ?file_location, ?dwg_description, ?project_id, ?created_by)"
        Dim sqlCommand As MySqlCommand
        sqlCommand = New MySqlCommand(qry, SQLConn)
        sqlCommand.CommandType = CommandType.Text
        With sqlCommand
            .Parameters.AddWithValue("?file_name", Arr(0))
            .Parameters.AddWithValue("?file_location", Arr(1))
            .Parameters.AddWithValue("?dwg_description", Arr(2))
            .Parameters.AddWithValue("?project_id", ProjName)
            .Parameters.AddWithValue("?created_by", Arr(2))
        End With
