5000 개 이상의 레코드를 반환하는 쿼리에 자동 번호 필드 추가

Question

해당 쿼리에 자동 번호 필드를 추가하면 ms 액세스가 응답하지 않습니다. SELECT (SELECT COUNT (*) FROM .....), * FROM ... 내 쿼리의 모든 열에 고유하지 않은 값이 있습니다. 새 열에 1,2,3,4, ...을 추가하고 싶습니다. 제 문제를 해결하도록 도와주세요.

Answer 1

죄송합니다, 그래서 여기에 완전히 다른 대답은, 아니 알려진 이유에 대한 쿼리 부분을 놓친 ...

를 사용하여 한 번만 기록을 읽은 다음 인 컬렉션의 ID를 저장이 기능 찾아보기가 훨씬 빠릅니다.

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.
