1、定时更新异网短信状态报告，后台程序接收状态报告errorcode和标示client_id存入yw_detail表中

2、log_yw_mobile、yw_detail、和sms_mt_send_detail+日期，三表关联更新数据

3、存储过程：

-------- 异网短信更新

create or replace procedure pro_update_yw_sms_detail is

TYPE TYPE_CURSOR IS REF CURSOR;

v_detail_cur TYPE_CURSOR;

v_sql varchar2(2500); ---------执行sql

v_day varchar2(2); ---------日期(天数)

v_errorcode number(10); ---------状态报告

v_ismg_status varchar2(40); ---------状态报告

v_msgid number(20); ---------detail表标示id

v_clientId varchar(40); ---------唯一标示id

v_start_time number(10); --------统计起始时间

v_end_time number(10); -------统计结束时间

i number; -----------处理的个数

begin

i:=0;

select date_to_num(sysdate) into v_start_time from dual;

open v_detail_cur for select msgid,client_id,dd,errorcode,statu from yw_detail_info;

loop

fetch v_detail_cur into v_msgid,v_clientId,v_day,v_errorcode,v_ismg_status;

if v_detail_cur%notfound then

exit;

end if;

execute immediate 'update sms_mt_send_detail'||v_day||' set ERRORCODE = '||v_errorcode||',ISMG_STATUS='''||v_ismg_status||''' where MT_SEND_DETAIL_ID ='||v_msgid;

i:=i+1;

if i>100 then

commit;

end if;

end loop;

close v_detail_cur;

v_sql:='delete from yw_detail where client_id in (select client_id from (select client_id from yw_detail order by client_id asc) where rownum

execute immediate v_sql;

select date_to_num(sysdate) into v_end_time from dual;

insert into log_procedures(create_time,procedure_name,deal_result,flag,deal_time)

values(sysdate,'异网短信状态更新：pro_update_yw_sms_detail','处理了'||i||'个数据',1,v_end_time-v_start_time);

commit;

end pro_update_yw_sms_detail;

4、视图view：

acreate or replace view yw_detail_info as

select "MSGID","CLIENT_ID","DD","ERRORCODE","STATU" from (select logg.msgid,logg.client_id,to_char(logg.send_time,'dd') dd,decode(detail.errorcode,'DELIVRD','0','0','0','1111') errorcode,decode(detail.errorcode,'0','DELIVRD','DELIVRD','DELIVRD',detail.errorcode) statu from log_yw_mobile logg

inner join yw_detail detail on logg.client_id = detail.client_id

order by logg.client_id asc ) where rownum<1000;

5、遇到的问题：

1)、ORA-00904: "EXPIR602": invalid identifier

这个是由于update的时候sms_mt_send_detail表中的errorcode是number类型，而上面取得的v_errorcode里面含有字母，所以一直报这个错。所以视图中把DELIVRD替换成0，其他的都替换成1111，这样插入就不会有问题了。

2)、ismg_status是varchar类型，所以得把引号带上:ISMG_STATUS='''||v_ismg_status||'''

3)、三张表关联时把关联的字段建立索引，如：

create index yw_detail_clientId on yw_detail(client_id);

4)、之前本来想着update一条就delete一条，感觉效率太低，直接每次取前1000条，删除起来就方便多了。

6、Job定时执行存储过程(每过五分钟执行一次)：

begin

sys.dbms_job.submit(job => :job,

what => 'pro_update_yw_sms_detail;',

next_date => to_date('21-11-2012 21:55:27', 'dd-mm-yyyy hh24:mi:ss'),

interval => 'sysdate+5/1440');

commit;

end;
