I need to get all distinct values from 10 different tables that exist in the field [favoritesport] And each table holds close to 50K records so I am looking at 500,000 records to get distinct values for. Would the fastest, less intrusive way of achieving this be to just create a UNION ALL so run
Select Distinct([favoritesport]) from table1 Union Select Distinct([favoritesport]) from table2 Union Select Distinct([favoritesport]) from table3 etc etc etc
