如果我尝试向users1表添加内容，则会出现此错误： “字段列表”中的未知列数

这是我的VB代码：

'INSERT INTO config（id，customer_id，domain） 'SELECT DISTINCT id，customer_id，domain FROM config;'

    Try

        ' Dim SqlQuery As String = "INSERT INTO presence(id_presence,id,hours,date) " & _
        '   "SELECT DISTINCT @Id_presence,@Id,@Hours,@Date FROM presence"


        'adding a new user

        Dim SqlQuery As String = "INSERT INTO users1(id,Nume,Prenume,username,password,onedrive,access, id_dep, id_pontaj) " & _
    "VALUES (0,@Nume,@Prenume,@Username,@Password,@Onedrive,@Access,@Iddep,@Idpontaj)"


        Using con = New MySqlConnection("Server = localhost;Database = accounts; Uid=root; Pwd = password")
            Using SQLcmd = New MySqlCommand(SqlQuery, con)
                con.Open()
                'SQLcmd.ExecuteNonQuery()

                'SQLcmd.Parameters.AddWithValue("@Id_presence", Convert.ToInt32(TextBox1.Text))
                'SQLcmd.Parameters.AddWithValue("@Id", Convert.ToInt32(TextBox2.Text))
                'SQLcmd.Parameters.AddWithValue("@Hours", Convert.ToInt32(TextBox3.Text))
                'SQLcmd.Parameters.AddWithValue("@Date", Convert.ToDateTime(TextBox4.Text))

                SQLcmd.Parameters.AddWithValue("@Nume", Convert.ToString(TextBox2.Text))
                SQLcmd.Parameters.AddWithValue("@Prenume", Convert.ToString(TextBox3.Text))
                SQLcmd.Parameters.AddWithValue("@Username", Convert.ToString(TextBox4.Text))
                SQLcmd.Parameters.AddWithValue("@Password", Convert.ToString(TextBox5.Text))
                SQLcmd.Parameters.AddWithValue("@Onedrive", Convert.ToString(TextBox6.Text))
                SQLcmd.Parameters.AddWithValue("@Access", Convert.ToInt32(TextBox1.Text))
                SQLcmd.Parameters.AddWithValue("@Iddep", Convert.ToInt32(TextBox7.Text))
                SQLcmd.Parameters.AddWithValue("@Idpontaj", Convert.ToString(TextBox8.Text))


                SQLcmd.ExecuteNonQuery()
            End Using
        End Using

    Catch ex As Exception
        MsgBox(" Failure to communicate " & vbCrLf & vbCrLf & ex.Message)
    End Try

可能是ID被视为保留（不确定原因），但尝试在字段列表中放置方括号[id]
