这在 Ms-access SQL 中是不可能做到的，你必须依赖 VBA
我有 20 分钟可以浪费，所以我为你做了...
将下表命名为TableSO
ID Start of range End of range
ID1 Ok-000001 Ok-000009
ID1 Ok-000010 Ok-000014
ID1 Ok-000015
ID1 Ok-000016 Ok-000018
ID1 Ok-000037 Ok-000042
ID2 Ok-000043 Ok-000045
ID2 Ok-000046 Ok-000052
下面的子生成你想要的报告
Public Sub TableSO_Treatment()

Dim strReport As String
Dim strStart As String
Dim strEnd As String
Dim lngStart As Long
Dim lngEnd As Long
Dim strCurrent As String

'init before loop
strLastStart = Trim(RST!start)
strPrevID = Trim(RST!ID)
strCurrent = Trim(RST!ID) & " " & strLastStart
' Loop on all records
While Not RST.EOF
' Init loop value
strID = RST!ID
strStart = Trim(NZ(RST!start,""))
strEnd = Trim(NZ(RST!end,""))
' if End Range empty give it the Start range value
If strEnd = "" Then strEnd = strStart
' Make numbers out of the ranges
lngStart = Val(Replace(strStart, "Ok-", ""))
lngEnd = Val(Replace(strEnd, "Ok-", ""))
' Test if it's a new ID
If strID <> strPrevID Then
' Its another ID !!!
' write new line
strReport = strReport & strCurrent & " - " & strPrevEnd & vbCrLf
'reinit curent line
strCurrent = strID & " " & strStart
strLastStart = strStart
End If
' Test if we are in a streak of ranges
If (lngprev + 1) = lngStart Then
' We are in a streak, do nothing
Else
' The streak is broken, write current streak and init a new streak
strCurrent = strCurrent & " - " & strPrevEnd & ", " & strStart
'reinit the start range
strLastStart = strStart
End If
' Saving previous values for the next loop
lngprev = lngEnd
strPrevEnd = strEnd
strPrevID = strID
RST.MoveNext
Wend
' Last write
strReport = strReport & strCurrent & " - " & strEnd & vbCrLf
' Et voila :)
Debug.Print strReport
End Sub
StrReport 包含：
ID1 Ok-000001 - Ok-000018, Ok-000037 - Ok-000042
ID2 Ok-000043 - Ok-000052
请注意，这与您提供的数据样本完美配合。如果您已经展示了所有可能性，它将适用于您的所有桌子。
但是您可能忘记指定一些特殊情况，您必须相应地调整程序以匹配它们。我已经正确注释了所有代码，以便您可以理解并在需要时自行修复。
这是唯一的方法。您将永远无法使用查询获得这样的报告，而 VBA 就在那里
编辑
在这种状态下，报告只会保存在内存中并打印在调试窗口中。这不是最佳选择。
您可以做的第一件事是：
- 创建表单
- 为其添加一个非常大的文本框，将其命名为
TextReport。
- 添加一个按钮，并在其点击事件中添加程序代码。
- 在程序的最后，添加指令
TextReport.Value = strReport
如果您有一张非常大的桌子，这仍然不是最佳选择。另一种可能性是将结果输出到文本文件中：
在 VBA 窗口的工具/参考下，检查库“Microsoft Scripting Runtime”
-
像这样调整过程，它会将报告输出到 C:/AccessReport.txt
