Hello -
I need to to query multiple Tables - each having the same structure - so here is some background that I hope provides a better understanding of my situation.
First off - I acknowledge that having multiple Tables with the same structure is not good database design. The Tables were built many years ago, when my knowledge of Access was very limited.
I have three Tables, each named by month (Jan;Feb;Mar). Each Table has 20 fields which include: First_Name; Last_Name; Van_#; Month; etc.
The same persons (First_Name; Last_Name) have participated in the same van or different vans during the three-month time period.
I believe I have to use a Union Query to combine information from the three Tables. I have accomplished this, but where I'm stuck is in trying to figure out how to report, for example: Bill Smith rode in van 334 in January and February, but rode in van 552 in March. How do I design a query to show this result?
Your advice and attention to this email is very much appreciated!
