Question

当我运行以下声明时，我在条件表达式错误中遇到数据类型不匹配，我已经把它拆开了，并且因为我的生活无法看出它出了什么问题！可能由于我的初学者知识水平，但它尽我所能！

这是我的代码;

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
    Dim UserName As String
    UserName = System.Environment.UserName
    Dim Month = Date.Now.ToString("MM")
    Dim CS As ConnectionStringSettings = ConfigurationManager.ConnectionStrings("ConnCIM")
    Dim Table As New DataTable
    Dim Adapt As New OleDbDataAdapter("SELECT [LoginName], [DisplayName], [Date], [SessionID], [The wait time was acceptable] , [The length of the chat session was appropriate] , [Professionalism of the agent] , [Effectiveness of the response] , [Overall opinion of the chat service] , [Related Comments] , [Not Resolved Comments] FROM [Chat_Dump] WHERE (([LoginName] = @UserName) AND ([Date] = @Month))", CS.ToString())
    Adapt.SelectCommand.Parameters.AddWithValue("@UserName", Textbox1.text)
    Adapt.SelectCommand.Parameters.AddWithValue("@Month", TextBox2.Text)

    TextBox2.Text = Month


    Adapt.Fill(Table)

    GridView1.DataSource = Table
    GridView1.DataBind()

End Sub

文本框仅用于测试，文本框1替换为UserName，我希望textbox2替换为Month。

简而言之，我有一个数据表，当每个用户查看时，我希望它从域登录中提取用户名并显示当前月份的记录。

谢谢！抱歉我的知识水平很低！

如果[Date]是DATETIME，您需要从中提取月份，然后与月份值进行比较。

... AND MONTH([Date]) = @Month

（整数DateTime.Now.Month是ToString("MM")）
