mysql的where子句中的条件日期未过滤

Question

我已经编写了上面的代码，它从用户那里获取它的值。 它的工作，但日期过滤器不工作。 相反，即使提供了日期，它也会显示表中的所有记录。

可能是什么问题？

$exp_query = "SELECT DISTINCT property_name, property_id, Water_charges, bank_charges, charge_1_description, other_charges_1,
                charge_2_description, other_charges_2, dates ";
$exp_query .="FROM expenses ";
$exp_query .="WHERE
              1=1
              AND (property_name= '".$property."'
                    OR dates BETWEEN '".$datefro."' AND '".$dateto."' )
                ";

Answer 1

AND 和 OR 之间有区别，还有如何在 AND 条件下使用 OR。 您在括号中使用了 OR 条件，请检查它们。

$exp_query = "SELECT DISTINCT property_name, property_id, Water_charges, bank_charges, charge_1_description, other_charges_1,
                charge_2_description, other_charges_2, dates ";
$exp_query .="FROM expenses ";
$exp_query .="WHERE property_name= '".$property."'
              AND (dates BETWEEN '".$datefro."' AND '".$dateto."' )";

Answer 2

假设您在MYSQL查询中使用了正确的条件

只需使用MYSQL DATE()函数，例如：

$exp_query = "SELECT DISTINCT property_name, property_id, Water_charges, bank_charges, charge_1_description, other_charges_1,
                charge_2_description, other_charges_2, dates ";
$exp_query .="FROM expenses ";
$exp_query .="WHERE
              1=1
              AND (property_name= '".$property."'
                    OR DATE( dates ) BETWEEN '".$datefro."' AND '".$dateto."' )
                ";
