1、创建触发器：
--倘若同一个业务的某种规则黄牌的置牌时间小于预警的置牌时间，--则交换他们的置牌时间。create or replace trigger after_punish_update_time after insert on winf_sv_punish for each rowdeclare param_id varchar2(100);--置牌ID param_breakRule varchar2(100);--违反规则 param_punishResult varchar2(2);--置牌结果（预警，异常，黄牌，红牌） param_sblsh varchar2(100);--申办流水号 param_yuJingPunishId varchar2(2);--置牌预警的ID param_smallDate date;--预警的置牌时间 param_bigDate date;--黄牌的置牌时间 begin param_id:=:new.id; param_breakRule:=:new.break_rule; param_punishResult:=:new.punish_result; param_sblsh:=:new.sblsh; param_bigDate:=:new.break_time; --查询出该业务的某个规则的预警ID,预警置牌时间 select p.id,p.break_time into param_yuJingPunishId,param_smallDate from winf_sv_punish p where p.break_rule =( select r.id from winf_sv_rule r left join winf_sv_supervisepoint sp on r.supervise_point=SP.ID where r.supervise_point=( select r.supervise_point from winf_sv_rule r where r.id=param_breakRule ) and r.rule_punish=‘1‘) and p.sblsh=param_sblsh and p.punish_result=‘1‘;--规则置牌结果为黄牌 if param_punishResult=‘2‘ and param_bigDate<param_smallDate then--定义游标查出该部门的核查负责人，若有则发送（状态为0），没有则暂存到待交办任务中（状态为-1） dbms_output.put_line(‘申办流水号：‘||param_sblsh||‘黄牌ID‘||param_id||‘预警ID‘||param_yuJingPunishId); --交换置牌时间 update winf_sv_punish p1 set p1.break_time=param_smallDate where p1.id=param_id; update winf_sv_punish p2 set p2.break_time=param_bigDate where p2.id=param_yuJingPunishId;end if; EXCEPTION WHEN NO_DATA_FOUND THEN null;end after_punish_update_time;
2、执行测试语句，报错：-- Created on 2014/10/16 by LAIWENHUA declare -- Local variables here i integer;begin -- Test statements here insert into WINF_SV_PUNISH (id, BREAK_RULE, BREAK_TIME, SBLSH, PUNISH_LEVEL, PUNISH_RESULT, OPERATE_TYPE, PUNISH_USERID, PUNISH_EXPLAIN, ISHANDLE, punish_type, NODE_ID, send_status, send_lead_status, IS_CONFIRM, CONFIRM_TIME) values (‘81af91db3c1b49a6a0f62b522275007a‘, ‘2f105e0797f84ea5b0cceb6a3f43b7fa‘, to_date(‘2014-10-16 23:07:50‘, ‘yyyy-mm-dd hh24:mi:ss‘), ‘YC-20141011009‘, ‘1‘, ‘2‘, ‘2‘, ‘3d12f197c5a04f2a8617d591acbf6ea9‘, ‘您所负责的业务申请歇业烟草专卖零售许可证,‘, ‘2‘, ‘1‘, ‘E939179C76C74BE5B29ECA958A3CD67E‘, ‘2‘, ‘2‘, ‘1‘, to_date(‘2014-10-16 23:07:50‘, ‘yyyy-mm-dd hh24:mi:ss‘));--(String)end;
3、解决方法：加上自治事务即可。
在declare后加上PRAGMA AUTONOMOUS_TRANSACTION;
表 XXX 发生了变化 触发器不能读它
