添加自动编号字段以查询返回5000条以上记录

Question

在该查询中添加自动编号字段会导致ms-access无响应。我用 SELECT（SELECT COUNT（*）FROM .....），* FROM ... 我的查询在每一列中都有非唯一值。我只是想在新的列中添加1,2,3,4 ...。请帮我解决我的问题。

对不起，错过了查询部分原因不明，所以这里是一个完全不同的答案......

使用此功能，读取记录只有一次，然后一个集合，是在商店的ID查找速度要快得多：

Public Function RowCounter(_ 
    ByVal strKey As String, _ 
    ByVal booReset As Boolean, _ 
    Optional ByVal strGroupKey As String) _ 
    As Long 

' Builds consecutive RowIDs in select, append or create query 
' with the possibility of automatic reset. 
' Optionally a grouping key can be passed to reset the row count 
' for every group key. 
' 
' Usage (typical select query): 
' SELECT RowCounter(CStr([ID]),False) AS RowID, * 
' FROM tblSomeTable 
' WHERE (RowCounter(CStr([ID]),False) <> RowCounter("",True)); 
' 
' Usage (with group key): 
' SELECT RowCounter(CStr([ID]),False,CStr[GroupID])) AS RowID, * 
' FROM tblSomeTable 
' WHERE (RowCounter(CStr([ID]),False) <> RowCounter("",True)); 
' 
' The Where statement resets the counter when the query is run 
' and is needed for browsing a select query. 
' 
' Usage (typical append query, manual reset): 
' 1. Reset counter manually: 
' Call RowCounter(vbNullString, False) 
' 2. Run query: 
' INSERT INTO tblTemp (RowID) 
' SELECT RowCounter(CStr([ID]),False) AS RowID, * 
' FROM tblSomeTable; 
' 
' Usage (typical append query, automatic reset): 
' INSERT INTO tblTemp (RowID) 
' SELECT RowCounter(CStr([ID]),False) AS RowID, * 
' FROM tblSomeTable 
' WHERE (RowCounter("",True)=0); 
' 
' 2002-04-13. Cactus Data ApS. CPH 
' 2002-09-09. Str() sometimes fails. Replaced with CStr(). 
' 2005-10-21. Str(col.Count + 1) reduced to col.Count + 1. 
' 2008-02-27. Optional group parameter added. 
' 2010-08-04. Corrected that group key missed first row in group. 

    Static col  As New Collection 
    Static strGroup As String 

    On Error GoTo Err_RowCounter 

    If booReset = True Then 
    Set col = Nothing 
    ElseIf strGroup <> strGroupKey Then 
    Set col = Nothing 
    strGroup = strGroupKey 
    col.Add 1, strKey 
    Else 
    col.Add col.Count + 1, strKey 
    End If 

    RowCounter = col(strKey) 

Exit_RowCounter: 
    Exit Function 

Err_RowCounter: 
    Select Case Err 
    Case 457 
     ' Key is present. 
     Resume Next 
    Case Else 
     ' Some other error. 
     Resume Exit_RowCounter 
    End Select 

End Function
