Php 如何在mysql中转到上一个日期

我必须检查车辆的有效期，我取了1天的间隔，但它取正值，因此它没有显示为过期，而是取正值，明天显示为过期

SELECT   
vehicle_reg_num,
vehicle_type,
insurance_validity,
tax_validity,
fc_validity
 FROM vms_vehicles_list 
WHERE ((insurance_validity BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 7 DAY) 
OR insurance_validity BETWEEN DATE_ADD (NOW(),INTERVAL -7 DAY) AND NOW()) 
OR (tax_validity BETWEEN NOW() AND DATE_ADD(NOW(),INTERVAL 7 DAY) 
OR tax_validity BETWEEN DATE_ADD(NOW(),INTERVAL -7 DAY) AND NOW())
OR (fc_validity BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 7 DAY)) 
OR fc_validity BETWEEN DATE_ADD(NOW(),INTERVAL -7 DAY) AND NOW()) 
AND vehicle_delete_flag=0;

您的查询应该是这样的

    SELECT 
vehicle_reg_num,
vehicle_type,
insurance_validity,
tax_validity,
fc_validity
 FROM vms_vehicles_list 
WHERE ((insurance_validity BETWEEN NOW() AND SUBDATE(NOW(),7) 
OR insurance_validity BETWEEN SUBDATE(NOW(),7) AND NOW()) 
OR (tax_validity BETWEEN NOW() AND SUBDATE(NOW(),7) 
OR tax_validity BETWEEN SUBDATE(NOW(),7) AND NOW()) 
OR (fc_validity BETWEEN NOW() AND SUBDATE(NOW(),7))) 
OR fc_validity BETWEEN SUBDATE(NOW(),7) AND NOW()) AND vehicle_delete_flag=0;
