主题：这样分次处理也会出现错误？！

.NET Framework 版本：2.0.50727.8825
Foxtable 版本：2018.8.30.1
错误所在事件：加载[HstDtl]失败!
详细错误信息：
查询超时已过期

有关代码如下：IDDtl表中的数据是HstDtl中ID唯一值的信息，HstDtl中每一个ID的相关记录不会超过100行

For i As Integer = 6272450 To 8974340
    For k As Integer = 1 To 2702       
        Dim m,n As Integer
        m = 6272449 + (k-1) * 1000 + 1
        n = 6272449 + k * 1000
        DataTables("IDDtl").LoadFilter = "[_Identify] >= " & m & " And [_Identify] <= " & n
        DataTables("IDDtl").Load
        For Each dr As Row In Tables("IDDtl").Rows
            Dim id As String = dr("ID")
            output.Show(id)
            DataTables("HstDtl").LoadFilter = "[ID] = '" & id & "'"
            DataTables("HstDtl").Load
            Tables("HstDtl").Sort = "出货日期"
            Dim t As Integer = Tables("HstDtl").Rows.Count
            Dim r As Row = Tables("HstDtl").Rows(n-1)
            r("Lst") = t-1
            DataTables("HstDtl").ReplaceFor("TJ",True)
            DataTables("HstDtl").Save
        Next
    Next
Next
MessageBox.Show("OK")
