dropping rows with a duplicate column name

    I have a query that produces unique rows. However, some of the unique rows have the column called testname that has the same test listed more than once. All I want to do is drop the older testname and keep the testdate column.

    Select

    Distinct

    TestID,

    TestDate,

    TestName

    From third.test

    I want to keep testdate in the query....guessing I need to put in to a temp table then drop the oldest one somehow by doing a subquery using Select Max....
