SQL Distinct List for fields in very large tables
Posted on 2014-11-02
I need to create a distinct list of values for columns in tables that are between 5 and 10 million records.
These lists can be up to 200,000 records long. At the moment I am creating them while my app runs and
it takes a long time. How do I get around this? Should I create views or tables that have a distinct list?
