Add LIMIT 1 to your query.

I assume you are talking of something like

SELECT  *
FROM    mytable
GROUP BY
        column

You shouldn't use unaggregated expressions in GROUP BY unless they are all same within the group.

If you want to return the record holding the least value of an expression within a group, use this:

SELECT  mo.*
FROM    (
        SELECT  DISTINCT column
        FROM    mytable
        ) md
JOIN    mytable mo
ON      mo.id = 
        (
        SELECT  id
        FROM    mytable mi
        WHERE   mi.column = md.column
        ORDER BY
                mi.column, mi.someorder
        LIMIT 1
        )
