Here is what I have now. One table with dates and one table like below. Query SQL as below. This works great. SELECT T_PriceCurrent.SDate, (Select Price from T_PriceIndex as T1 where T1.SDate=(Select Max(SDate) from T_PriceIndex AS T2 where T2.SDate<=T_PriceCurrent.SDate)) AS PriceCurrent FROM T_PriceCurrent; SDate Price 1/1/2005 8.56 1/23/2005 8.73 2/14/2005 8.40 3/1/2005 8.00 3/12/2005 8.45 3/27/2005 8.95 4/7/2005 8.12 4/30/2005 7.95 5/14/2005 8.03 5/27/2005 8.24 6/10/2005 9.03 6/25/2005 9.17 7/3/2005 9.25 7/27/2005 9.40 8/3/2005 9.64 What I cannot figure how to do is make it work if table looks like below. I need output for each Pattern. Pattern SDate Price 1 1/1/2005 8.56 1 1/23/2005 8.73 1 2/14/2005 8.40 1 3/1/2005 8.00 1 3/12/2005 8.45 1 3/27/2005 8.95 1 4/7/2005 8.12 1 4/30/2005 7.95 1 5/14/2005 8.03 1 5/27/2005 8.24 1 6/10/2005 9.03 1 6/25/2005 9.17 1 7/3/2005 9.25 1 7/27/2005 9.40 1 8/3/2005 9.64 2 1/7/2005 8.27 2 1/24/2005 8.71 2 2/13/2005 8.35 2 3/2/2005 8.02 2 3/13/2005 8.44 2 3/28/2005 8.93 2 4/6/2005 8.10 2 4/28/2005 7.98 2 5/15/2005 8.05 2 5/25/2005 8.20 2 6/9/2005 9.00 2 6/20/2005 9.15 2 7/1/2005 9.23 2 7/25/2005 9.35 2 8/4/2005 9.65 2 8/15/2005 9.50 Thanks for any ideas. -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Hale, Jim Sent: Tuesday, November 14, 2006 3:59 PM To: 'Access Developers discussion and problem solving' Subject: Re: [AccessD] Carry Forward in a query If I understand what you want to do, I have done this with a non cartesian join. I create a table with a one field record and one record for each date. In the query window I place this table and the table with the record you want to duplicate WITHOUT ANY JOIN. the resulting data set produces one record for each date.

I would like to generate a record for every month using the previous months data until there is data for the current records month. I can do this in code but had a coworker ask if it could be done in a query. I am not coming up with an answer. Your thoughts please.
