I believe you need a main table where youn list all the colleges with columns for STATE, CONGRESSIONAL DISTRICT and REPRESENTATIVE.
And those three columns would be pulled from three table catalogs: STATES, CONGRESSIONAL DISTRICTS and REPRESENTATIVES. Maybe there is a better approach, but I don't know the way your states or country is organized.

I want each college to appear once matched to each congressional district (that is in one table and is easy to do) and also include a column from a second table with the Representative. My syntax, below, produces far too many results, matching college and district and Representative many times. The syntax: select a.college, a.state, a.cd, b.rep from a, b where a.state = "al" and a.cd = "3" or a.state = "az" and a.cd = "1" and a.state = b.state and a.cd = b.cd What do I do to limit to single match for each college in the specified congressional districts?
