PostgreSQL - making first row show as total of other rows

Question

Is there any way to make first row be different then the rest, so it would show total sum of the appropriate columns?

For example:

      fruits|a|b|c
            


        

Answer 1

SELECT 'total' AS fruits, sum(a), sum(b), sum(c) FROM basket
UNION ALL
SELECT fruits, sum(a), sum(b), sum(c) FROM basket GROUP BY fruits
