"select sum(allsell), sum(softsell), sum(selfpro), sum(export_earn) from stat_c where stat_time='".$txtYear.$sltMonth."' and corporation_id in (select c_id from corporation where c_import='Y')";
"select sum(allsell), sum(softsell), sum(selfpro), sum(export_earn) from stat_c where stat_time='".$txtYear.$sltMonth."' and corporation_id in (select c_id from corporation where c_import='Y')";
