如何使用PHP PDO中的birth_date检索以上所有60岁的年龄？

Question

我想使用birth_date显示年龄在60岁以上的所有客户。 bith_date的类型为date。这是birth_date-> 1999-03-12的格式。有人可以帮我解决我的问题吗？

$sql = "SELECT * FROM `tbl_beneficiary` INNER JOIN tbl_barangay ON 
        tbl_beneficiary.barangay_id = tbl_barangay.barangay_id WHERE 
        tbl_beneficiary.is_active = 'No' AND (DATEDIFF(NOW(), 
        tbl_beneficiary.birth_date) <= 60) ORDER BY 
        tbl_beneficiary.beneficiary_id";

Answer 1

我尚未对其进行测试，但是我认为这应该可以工作（它使用表别名以方便阅读）

SELECT * FROM `tbl_beneficiary` be
    INNER JOIN tbl_barangay ba ON be.barangay_id = ba.barangay_id 
WHERE 
    be.is_active = 'No' AND YEAR( FROM_DAYS( TO_DAYS( NOW() ) - TO_DAYS( be.birth_date ) ) ) > 60 
ORDER BY 
    be.beneficiary_id

或更简单

SELECT * FROM `tbl_beneficiary` be
    INNER JOIN tbl_barangay ba ON be.barangay_id = ba.barangay_id 
WHERE 
    be.is_active = 'No' AND TIMESTAMPDIFF(YEAR, be.birth_date, CURDATE()) > 60 
ORDER BY 
    be.beneficiary_id

Answer 2

您可以使用：

$sql = "SELECT * FROM `tbl_beneficiary` INNER JOIN tbl_barangay ON 
        tbl_beneficiary.barangay_id = tbl_barangay.barangay_id WHERE 
        tbl_beneficiary.is_active = 'No' AND tbl_beneficiary.birth_date<=DATE_SUB(NOW(),INTERVAL 60 Years) ORDER BY 
        tbl_beneficiary.beneficiary_id";
