Alright I don't know if this can be done but I've been given this task by higher ups so I ahve to at elast try. The database I'm using has different tables going abck once a month for pending sales. These are each essentaily a snapshot in time of how far along the sales are and how many of them are in the pipeline. I need to do some basic analysis on this data. Is there a way to build a query that finds something about one table (say sums the revenue for january) but using some form of input can be switched to using another table? (like than summing the revenue for March.) I'll be checking this thread pretty often until I either find a solution or become convinced this won't work right so don't hesitate to ask any clarifying questions.
