Re: SQL to bunch rows together?

select min(column_a), column_b, sum(column_c) from my_table group by column_b;

column_a column_b column_c
-------- -------- --------

    1          abc         190
    2          cdf         78

Of course it selects two columns (b & c) as you needed and gives you minimum from coulmn_a.
Later you can do sth about column_a.
