主题：请教动态加载问题(已解决)

某个外部表加载条件设置了  [_Identify] Is NULL，正常显示为没有加载数据

在命令窗口测试下面代码显示正常，

<!--?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /--> 

Dim y As Integer = Date.Today.Year
Dim m As Integer = Date.Today.Month
Dim dt1 As New Date(y, m, 1)
Dim dt2 As New Date(y, m, Date.DaysInMonth(y, m)) '获取本月的最后一天
Dim Filter As String
  Filter = "日期 >=  '" & dt1 & "' And 日期 <= '" & dt2 & "'"
  With DataTables("各项消耗")

.LoadFilter = ""

.LoadFilter = Filter

.Load()

End With
