Subject: how to replace file's content directly?

I have a sql file exported from mysql,and want to chang the charecter
set to utf-8.

sqltempfile=File.new(sqltemp,'w+')  ### How to get rid of it?
File.open(sqlfile,'r+') do |file|
    lines=file.gets(nil)
    lines.gsub!(/TYPE=MyISAM/){|match| match='DEFAULT CHARACTER SET
utf8'}
    sqltempfile.puts lines             ### How to get rid of it?
end
sqltempfile.close                        ### How to get rid of it?

And the question is,how to replace the string directly without
sqltempfile?
Anyone help me?
