mysql的where子句中的条件日期未过滤

Question

I have written the code above which gets its values form a user. Its working but the date filter isn't working. Instead its displaying all the records in the table even when the dates are provided.

What could be the issue?

$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

There is difference between AND and OR, also how to use OR with AND condition. You have used an OR condition in parentheses, check them.

$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

Assuming you are using right condition in your MYSQL query

just use MYSQL DATE() function like::

$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."' )
                ";
