以下查询:
$today = date('Y-m-d');
$sql = "SELECT * FROM table WHERE day1 = '$today' AND country = 'India' OR day2 = '$today' AND country = 'India' OR day3 = '$today' AND country = 'India' OR day4 = '$today' AND country = 'India' OR day5 = '$today' AND country = 'India' OR day6 = '$today' AND country = 'India' OR day7 = '$today' AND country = 'India' OR day8 = '$today' AND country = 'India' OR day9 = '$today' AND country = 'India' OR day10 = '$today' AND country = 'India'";
if($_POST!=""){
$mydate = mysql_real_escape_string($_POST['datepicker']);
if($mydate!=""){
$sql = "SELECT * FROM table WHERE day1 = '$mydate' AND country = 'India' OR day2 = '$mydate' AND country = 'India' OR day3 = '$mydate' AND country = 'India' OR day4 = '$mydate' AND country = 'India' OR day5 = '$mydate' AND country = 'India' OR day6 = '$mydate' AND country = 'India' OR day7 = '$mydate' AND country = 'India' OR day8 = '$mydate' AND country = 'India' OR day9 = '$mydate' AND country = 'India' OR day10 = '$mydate' AND country = 'India'";

它与日期选择器链接。仅在同一页面中回显。想要在同一页面中添加以下选择语句....如果用户单击“接下来 10 天的计划”。
select * from table WHERE (day1 >= CURRENT_TIMESTAMP
AND country = 'India'
AND day1 <= CURRENT_TIMESTAMP + INTERVAL 10 DAY
AND country = 'India')
OR
(day2 >= CURRENT_TIMESTAMP
AND country = 'India'
AND day2 <= CURRENT_TIMESTAMP + INTERVAL 10 DAY
AND country = 'India')
......till day10
最佳答案
SELECT * FROM table
WHERE (
(day1 BETWEEN NOW() AND NOW() + INTERVAL 10 DAY)
OR (day2 BETWEEN NOW() AND NOW() + INTERVAL 10 DAY)
OR (day3 BETWEEN NOW() AND NOW() + INTERVAL 10 DAY)
OR (day4 BETWEEN NOW() AND NOW() + INTERVAL 10 DAY)
OR (day5 BETWEEN NOW() AND NOW() + INTERVAL 10 DAY)
OR (day6 BETWEEN NOW() AND NOW() + INTERVAL 10 DAY)
OR (day7 BETWEEN NOW() AND NOW() + INTERVAL 10 DAY)
OR (day8 BETWEEN NOW() AND NOW() + INTERVAL 10 DAY)
OR (day9 BETWEEN NOW() AND NOW() + INTERVAL 10 DAY)
OR (day10 BETWEEN NOW() AND NOW() + INTERVAL 10 DAY)
)
AND country = 'India'
