下面的時間範圍查詢都是前閉後開，如 $time_start <= time < $time_end
if $day_index == 1 then #今天資料
set $time_start = UNIX_TIMESTAMP(DATE_ADD(DATE_SUB(CURDATE(),INTERVAL 0 DAY),INTERVAL 0 HOUR));
set $time_end = UNIX_TIMESTAMP(DATE_ADD(DATE_SUB(CURDATE(),INTERVAL 0 DAY),INTERVAL 24 HOUR));
elseif $day_index == 2 then #昨天資料
set $time_start = UNIX_TIMESTAMP(DATE_ADD(DATE_SUB(CURDATE(),INTERVAL 1 DAY),INTERVAL 0 HOUR));
set $time_end = UNIX_TIMESTAMP(DATE_ADD(DATE_SUB(CURDATE(),INTERVAL 1 DAY),INTERVAL 24 HOUR));
elseif $day_index == 3 then #7天資料
set $time_start = UNIX_TIMESTAMP(DATE_ADD(DATE_SUB(CURDATE(),INTERVAL 6 DAY),INTERVAL 0 HOUR)); #6天前 set $time_end = UNIX_TIMESTAMP(DATE_ADD(DATE_SUB(CURDATE(),INTERVAL 0 DAY),INTERVAL 24 HOUR)); #今天結束
elseif $day_index == 4 then #本月資料
set $time_start = UNIX_TIMESTAMP(DATE_ADD(DATE_SUB(curdate(), INTERVAL 0 MONTH),INTERVAL 0 DAY)); #本月開始
set $time_end = UNIX_TIMESTAMP(DATE_ADD(DATE_SUB(CURDATE(),INTERVAL 0 DAY),INTERVAL 24 HOUR)); #今天結束
elseif $day_index == 5 then #上月資料
set $time_start = UNIX_TIMESTAMP(DATE_ADD(DATE_SUB(curdate(), INTERVAL 1 MONTH),INTERVAL 0 DAY)); #上月開始 set $time_end = UNIX_TIMESTAMP(DATE_ADD(DATE_SUB(curdate(), INTERVAL 0 MONTH),INTERVAL 0 DAY)); #本月開始
end if;
