Little help with query_sql please

[Moooooon-Aisha]

    for(.@i = 0; .@i <= 38; .@i++)
        query_sql("DELETE FROM `achievement` WHERE `achievement`.`id` = 40000"+.@i+";"

I am currently using this code to reset my achievements, is there any other way to avoid using multiple query_sql (since its a loop)

Thanks. I'm using this to manipulate offline player data.

DELETE FROM `achievement` WHERE `achievement`.`id` >= '400000' AND id <= '4000038';

is it me or there is really wrong number in the loop.
concated value become like this:
lower bound 40000+0 = 400.000, then upper bound 40000+38 = 4.000.038

Thanks, I typed it with an extra 0 in there, it should all be within the 400,000 range. Thank you very much!
