如何判断数据集存在
我经常要用模块调用数据集，每次调用都要执行这个模块．反复调用效率太低．

Dim FileName As String, AccessTable As String
FileName = "Equipment.mdb "
AccessTable = "Equipment_Material "
Dim rst As ADODB.Recordset
　用以下语句出错
'If rst = False Then
Set rst = AboutAccess.rstInputData(FileName, AccessTable, "* ")
'End If

找了一些资料，没有解决．请教各位大侠了．


[解决办法]
NOT RST IS NOTHING
