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;
