提取小于mysql的限制值

Question

我尝试只显示在最后一天提交的文章，限制为5，但我有一个问题，如果在一个类别中存在少于5篇文章，我不想显示重复，只显示1,2,3,4篇文章，怎么办？谢谢！

$Time=time(); 
$LimitDay=$Time - 86400; 
$SelectArticle=mysqli_query($ConnecDB, "SELECT * FROM mk_sn_article WHERE art_category='$Display[CategorieMail]' AND art_data BETWEEN '$LimitDay' AND '$Time' ORDER BY art_id DESC LIMIT 5");

Answer 1

SELECT * FROM mk_sn_article WHERE art_category='$Display[CategorieMail]' AND art_data > DATE_SUB(NOW(), INTERVAL 1 DAY) ORDER BY art_id DESC LIMIT 5

只需使用DATE_SUB进行比较 - 它将拉出所有-24h文章
