MS Access 2003 Sub Query
Posted on 2015-01-28
In an access query, I would like to produce a set of results that includes all customers that responded to a particular promotion. That is the easy part. I would like to include in my query results the response date, the last date of any order that preceded the response date and the date of the first order that proceeded the response date.
To do this, I believe that I need some sub queries, but I am not sure how to construct them in respect to linking them the customer number and response date of the underlying query.
Any help would be gratefully appreciated.
