declare
cursor ssm_send_cur is
select *
from sms_send_wait ssw left join sms_send_receive ssr on ssr.sms_id = ssw.sms_id
where not exists
(select ssrb.phone_number
from sms_send_receive_blacklist ssrb
where ssrb.phone_number=ssw.phone_number) and ssw.send_wait_time between sysdate-1 and sysdate+1
begin
--循环获取游标中的记录
for sms_send_rec in sms_send_cur
loop
update sms_send_wait ssw set ssw.verify_state = '0'
where ssw.pbone_number = sms_send_rec.phone_number;
end loop;
end;
