is it a Many-to-Many relationship ???

Ok, pardon: Table1: ID,weight,m_weight,height,m_height Table2: ID,measure_name This is the question: I've to build a query that gives me with a single select, two rows of the table2. If you can, please give me some hints about this problem: store data with relatives measure units, and a way to make format conversions: for example convert lire to euro, or gr. to kg. I'm thinking to store in table2 the conversion values. ciao ______________________________________________________________________ Abbonati a Yahoo! ADSL con Atlanet!
