I have two years worth of sales data, 2011 and 2012 YTD. I would like to compare daily activity against each other for example August 1 against August 1 from different years. There will be as many as 500 orders in a day. The date fields have the year associated with each record, example, 1-JUL-2011. There is really no unique field associated in each table. Any suggestions would be greatly appreciated. I have tried a lot of things but nothing really "clean". Thanks.
