Can anyone tell me whether I need to use Perl to do the following SQL commands (for MS SQL Server 7). I wish to: 

SELECT DISTINCT Aggregated_area
FROM Geo_postaggregated_pop_count_Ward;

Take each of these values and then where Aggregated_area = each distinct value do the following: 

UPDATE Geo_postaggregated_pop_count_Ward
SET Sum_male_count =
        (SELECT SUM(G.Person_count)
      FROM Geo_postaggregated_pop_count_Ward G
      WHERE Sex = 1);

UPDATE Geo_postaggregated_pop_count_Ward
      SET Sum_female_count =
              (SELECT SUM(G.Person_count)
            FROM Geo_postaggregated_pop_count_Ward G
            WHERE Sex = 2);

UPDATE Geo_postaggregated_pop_count_Ward
            SET Sum_of_person_count =
                    (SELECT SUM(G.Person_count)
                  FROM Geo_postaggregated_pop_count_Ward G
                  WHERE Sex = 1 OR
                       Sex = 2);

Do I really need to use the Perl foreach command to do this?
