2016年要学会用存储过程向关联的几张表里面插入数据。

第一次操作多张相关联的数据库表，傻傻的去做一张一张的操作。结果发现写sql语句去Low数据，发现怎么都Low不出来。事后（也就是现在，我先笑一笑）

向6张表里插入数据：

insert into DE_CONTRACT_INFO (id,RECORD_TYPE,ID_DE_RULE_CHECK_REQ,CDATE,EDATE,CREATOR,EDITOR,STATUS)  values(1,1,1,sysdate,sysdate,'pd','pd1','a');

insert into de_external_ds (id,ID_DE_RULE_CHECK_REQ,CDATE,EDATE,CREATOR,EDITOR,STATUS)values(1,1,sysdate,sysdate,'pd','pd1','a');

insert into DE_HARD_CHECK (ID,ID_DE_RULE_CHECK_REQ,CDATE,EDATE,CREATOR,EDITOR,STATUS)values(1,1,sysdate,sysdate,'pd','pd1','a');

insert into DE_ONLINE_TRIGGERS(ID,ID_DE_RULE_CHECK_REQ,STATUS)values(1,1,'a');

insert into DE_ROUND (ID,ID_DE_RULE_CHECK_REQ,ROUND,RAND1,RAND2,RAND3,CDATE,EDATE,CREATOR,EDITOR,STATUS)values(1,1,1,1.1,1,1,sysdate,sysdate,'pd','pd1','a');

insert into DE_ROUND_RESULT(ID,ID_DE_ROUND,CDATE,EDATE,CREATOR,EDITOR,STATUS)values(1,1,sysdate,sysdate,'pd','pd1','a');

insert into  DE_RULE_CHECK_RESULT (ID,ID_DE_RULE_CHECK_REQ,CDATE,EDATE,CREATOR,EDITOR,STATUS)  values(1,1,sysdate,sysdate,'pd','pd1','a');

insert into De_Rule_Check_Req(ID,ID_DE_RULE_CHECK_REQ,CDATE,EDATE,CREATOR,EDITOR,STATUS)values(12,1,sysdate,sysdate,'pd','pd1','a');

insert into  de_round_result (ID,ID_DE_ROUND)  values(1,11);

查询6张表关联后的结果：

select  r.ID

  from de_rule_check_req rcr

  left join DE_CONTRACT_INFO ci1

    on (rcr.ID = ci1.ID_DE_RULE_CHECK_REQ and ci1.RECORD_TYPE = '1')

  left join DE_CONTRACT_INFO ci2

    on (rcr.ID = ci2.ID_DE_RULE_CHECK_REQ and ci2.RECORD_TYPE = '2')

  left join DE_HARD_CHECK hc

    on (hc.ID_DE_RULE_CHECK_REQ = rcr.ID)

  left join DE_ONLINE_TRIGGERS ot

    on (ot.ID_DE_RULE_CHECK_REQ = rcr.ID)

  left join DE_EXTERNAL_DS ed

    on (ed.ID_DE_RULE_CHECK_REQ = rcr.id)

  left join DE_WORKFLOW_ACT wa

    on (wa.ID_DE_RULE_CHECK_REQ = rcr.id)

  left join DE_ROUND r

    on (r.ID_DE_RULE_CHECK_REQ = rcr.ID and r.ROUND = 1)

  left join (select rr1.*, d.ID_DE_RULE_CHECK_REQ id_rcr, d.id id_last_round

               from de_round d, de_round_result rr1

              where d.ID = rr1.ID_DE_ROUND(+)

                and d.ROUND = 1 - 1) aa

    on (aa.id_rcr = rcr.id)

 where rcr.id_application = 504;

查询通过de之后返回的结果。

 select * from de_round_result where id_de_round=503;

怎么都查不出来，结果就是，去问数据库工程师，说是要关联的插入数据才能够查出一张综合的表出来。逻辑嘛，很麻烦。现在暂时还不太了解，是用了存储过程。。。
