Roughly, what I would do would look like this: dStartDate = DATE(2010,1,1) && adjust as needed dEndDate = DATE(2012,12,31) && ditto CREATE Cursor Results (dStartRange D, dEndRange D, nCount N(4,0)); DO WHILE dStartDate < dEndDate SELECT Count(*) as nCount from Gluctmp1 WHERE date between dStartDate and (dStartDate+20) INTO CURSOR OneRow INSERT INTO Results VALUES (dStartDate, dStartDate+20, OneRow.nCount) USE IN OneRow dStartDate = dStartDate + 1 ENDDO --- StripMime Report -- processed MIME parts --- multipart/alternative text/plain (text body -- kept) text/html --- _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://mail.leafe.com/mailman/listinfo/profox OT-free version of this list: http://mail.leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/CACW6n4tVD0ioPDc38m7Qhpaphez6+OFx=fEAd5Zo8A=wla4...@mail.gmail.com ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
