一、递归查询
1、表机构 SQL> desc comm_org_subjection Name Null? Type ----------------------------------------- -------- ---------------------------- ORG_SUBJECTION_ID NOT NULL VARCHAR2(32) 子键 ORG_ID NOT NULL VARCHAR2(32) FATHER_ORG_ID NOT NULL VARCHAR2(32) 父键 LOCKED_IF NOT NULL VARCHAR2(1) START_DATE NOT NULL DATE END_DATE DATE EDITION_NAMEPLATE NUMBER(8) CODE_AFFORD_IF VARCHAR2(1) CODE_AFFORD_ORG_ID NOT NULL VARCHAR2(32) CODING_SHOW_ID NUMBER(8) BSFLAG VARCHAR2(1) MODIFI_DATE DATE CREATOR_ID VARCHAR2(32) CREATE_DATE DATE CREATOR VARCHAR2(35) 2、递归查找父结点 org_id为C6000000000001下的所有子结点: select * from comm_org_subjection a start with a.org_id='C6000000000001' connect by prior a.org_subjection_id=a.father_org_id 3、递归查找子结点 org_id为C6000000000001下的所有父结点: select org_id from comm_org_subjection a start with a.org_id='C6000000000001' connect by prior a.father_org_id=a.org_subjection_id
