I want to compare [example] feb 2007 with feb 2008 sales figures for category,qty , $value etc but i want to make the date ranges by submitting parameters. All i get is thousands of results because the join is multiplying the data. Replies: Posted By: BrianBischof Date Posted: 28 Apr 2008 at 4:20pm The reason why you are getting thousands of records is probably because you are joining the same table to itself (so that both date ranges can be compared) and this produces a 'cartesian product' (which means you get thousands of duplicate records). Have you looked into using a crosstab object? This summarizes the data for you and puts the data side by side in two columns. You can also tell it to group by year. This might be what you need. I cover everything you need to know about cross-tab reports in my Encyclopedia book. You can find out more about my books at http://www.amazon.com/exec/obidos/ASIN/0974953601/bischofsystem-20 - Amazon.com or reading the http://members.crystalreportsbook.com - Crystal Reports eBooks online. ------------- Please support the forum!
