vb.net中的参数化MySql查询未传递给DB

Question

似乎无法将此传递给数据库我认为查询存在问题，任何帮助都表示赞赏。VS没有给出任何错误，这导致我认为问题与声明有关，遗憾的是我无法在navicat中测试它，因为它不是真正的价值观＃34;我尝试使用像这样的参数

Params.Add（New MySqlParameter（＆＃34; @ eventDate＆＃34;，eventDate））

和这样的参与者

Params.Add（New MySqlParameter（＆＃34; eventDate＆＃34;，eventDate））

两者的结果相同

Public Function ParameterizedNonQueryCommand(ByRef NonQuery As String, ByVal Parameters As List(Of MySqlParameter), _
        Optional ByVal Connection As MySql.Data.MySqlClient.MySqlConnection = Nothing) As Integer

        Dim comm As New MySql.Data.MySqlClient.MySqlCommand(NonQuery, Connection)
        Try
            For Each param As MySql.Data.MySqlClient.MySqlParameter In Parameters
                comm.Parameters.Add(param)
            Next
            If comm.Connection.State <> ConnectionState.Open Then comm.Connection.Open()
            comm.Prepare()
            Return comm.ExecuteNonQuery()
        Catch ex As Exception
            Return CType(False, Integer)
            MessageBox.Show(ex.Message)
        Finally
            comm.Connection.Close()
            comm.Dispose()
        End Try
    End Function
