在写存储过程的时候，有时不直接使用insert into 表名 values select * from XXX where XXX
而是使用游标进行数据的一条条插入，主要原因是数据库资源的问题。
使用insert直接插入整个查询的表的数据，数据库会等到都执行完成之后才能释放资源，若查询的过程比较慢，那么资源就一直处于使用状态。比较费资源。
若使用游标进行插入的话，可以设置游标多少条数据进行插入一次，然后释放一下资源。
游标的形式：
create or replace procedure PRC_RPN_REVISIT_REPORT is
cursor cur_rpn_revisit_report is
select A.*,
case when A.STATUS is not null and A.STATUS = '3'
then '回访不成功'
when A.STATUS is null and CONCAT(A.SERVICE_RESULT,' ') <> CONCAT( '不回访通过',' ')
then '回访成功'
when A.STATUS is null and A.SERVICE_RESULT ='不回访通过'
then '不回访通过'
end RINGBACK_STATUS--回访处理状态
