    Sql code for Distinct column and two other Columns

    I'm trying to return three columns of information with one column being distinct values and the other two columns of data of the distinct values only. I'm using access and was wondering if the column I'm trying to get Distinct is affected by being alphanumeric.

    SELECT Order Num, Trade Date,Cost Center Code,Man-Semi-Auto
    FROM 2011 Report
    WHERE Order Num IN (SELECT DISTINCT Order Num FROM 2011 Report);

    I though this would work but it is not returning Distinct or unique entries

    The subquery has DISTINCT, but the main query doesn't. Maybe if you could post an example of the source data and your desired result, we can recommend a method.

    Does this work?

    SELECT [Order Num], [Trade Date],[Cost Center Code],[Man-Semi-Auto]
    FROM [2011 Report]

    GROUP BY [Order Num], [Trade Date],[Cost Center Code],[Man-Semi-Auto]

    The spaces and symbols in your names will prove to be more trouble than they're worth in the long run.
