如何僅在 codeigniter 中顯示從今天的日期和月份到未來 3 個月的數據？

Question

所以，我有即將到期的員工合同數據，我想顯示未來 3 個月的今天月份和日期的員工數據。 我試過使用 DATEADD 或 DATE_ADD 但它仍然不起作用。 請幫忙

這是我的查詢：

SELECT a.fullname, a.employee_id, a.id_number, b.date_contract_from, b.date_contract_to AS expired,                                                                           
       b.is_current, b.is_deleted, b.employment_status 
FROM hr_employees a
INNER JOIN hr_employee_jobs b
ON a.id = b.employee                                                     
WHERE b.date_contract_to >= NOW()
AND b.employment_status IN ('1', '2')
AND b.is_current = 1
AND b.is_deleted = 0  AND a.is_deleted = 0
GROUP BY b.employee
ORDER BY b.date_contract_to ASC

這是它的外觀示例。 所以，應該不會出現4月份的到期日。

您可以像這樣在查詢和DATE_ADD function之間使用日期。

SELECT a.fullname, a.employee_id, a.id_number, b.date_contract_from, b.date_contract_to AS expired,                                                                           
       b.is_current, b.is_deleted, b.employment_status 
FROM hr_employees a
INNER JOIN hr_employee_jobs b
ON a.id = b.employee                                                     
WHERE b.date_contract_to BETWEEN now() AND  DATE_ADD(now(), INTERVAL 3 MONTH)
AND b.employment_status IN ('1', '2')
AND b.is_current = 1
AND b.is_deleted = 0  AND a.is_deleted = 0
GROUP BY b.employee
ORDER BY b.date_contract_to ASC
