Dim id1 As Integer = Tables("表A").Rows(Tables("表A").TopPosition)("_Identify")
    Dim id2 As Integer = Tables("表A").Rows(Tables("表A").BottomPosition)("_Identify")
    If DataTables("表A").Compute("count(物料编码)"," 价格= 0.00 and [_Identify] >= " & id1 & " And [_Identify] <= " & id2 & " ") > 0 


这代码有问题吗 ，明明有符合条件的，就算不出来

调试看看
Dim id1 As Integer = Tables("表A").Rows(Tables("表A").TopPosition)("_Identify")
msgbox(id1)
    Dim id2 As Integer = Tables("表A").Rows(Tables("表A").BottomPosition)("_Identify")
msgbox(id2)
msgbox(DataTables("表A").Compute("count(物料编码)"," 价格= 0.00 "))
msgbox(DataTables("表A").Compute("count(物料编码)"," 价格 is null"))
msgbox(DataTables("表A").Compute("count(物料编码)"," 价格 is null and [_Identify] >= " & id1 & " And [_Identify] <= " & id2))
msgbox(DataTables("表A").Compute("count(物料编码)","[_Identify] >= " & id1 & " And [_Identify] <= " & id2))
