mysql表按日期搜索

-1

我有mysql表的search.php。但是当我按日期搜索我得到这样mysql表按日期搜索

---request "Could not execute SQL query" SELECT * from pricelist WHERE date = '2017-08-07' AND 
---

错误我想它，因为日期格式，但我不能排序了这一点？

输入日期格式为dd.mm.yyyy 但MySQL的日期格式YYYY.MM.DD

'。$ search_string。$ search_customername'的值是否为空？ –

$SQL = "SELECT * FROM table_name WHERE * = * ORDER BY date DESC

或

$SQL = "SELECT * FROM table_name WHERE * = * ORDER BY date ASC

我使用的mysqli测试，并它的工作正常，如果你想按日期和时间分类

$SQL = "SELECT * FROM table_name WHERE * = * ORDER BY date DESC, time DESC
