SqlException和I'；我无法解决它

我在尝试执行查询时遇到了一个问题。我得到了这个错误：

找不到列“m”或用户定义函数或聚合“m.gender”，或名称不明确

代码：

当我直接在SQL Server中执行时，查询运行良好。问题是当它在我的应用程序中的按钮单击事件上执行时。（VB.NET）

请检查我的全部查询

我认为返回表和表模型具有相同的列名

Try m.model As Model2, m.gender AS Gender2,

请在定义MyCommand的位置显示代码。如果看不到它，我们就无法调试它。不要返回读取器，在执行它的地方使用它。您应该返回类似于

IEnumerable

的内容。这是因为我有一个类，我在其中放置了我经常使用的所有代码。让我编辑我的原始帖子如果您在ManagementStudio中运行sql，您应该会得到相同的错误，除非双击错误消息，它会将您带到导致错误的行。这应该有助于您将其隔离。@GarethD我在management studio中运行，它工作正常！

Public Shared Function ExecutaReader(ByVal strSQL)

        Dim strConn As String
        strConn = ConfigurationSettings.AppSettings("strConn")

        Dim myConnection As New SqlConnection(strConn)
        Dim myCommand As New SqlCommand(strSQL, myConnection)

        myConnection.Open()
        Dim myReader As SqlDataReader = myCommand.ExecuteReader()

        Return myReader


    End Function

Try m.model As Model2, m.gender AS Gender2,
