浅谈oracle树状结构层级查询

　　oracle树状结构查询即层次递归查询，是sql语句经常用到的，在实际开发中组织结构实现及其层次化实现功能也是经常遇到的，虽然我是一个java程序开发者，我一直觉得只要精通数据库那么对于java开发你就成功了三分之一，本篇中主要介绍start with...connect by prior 、order by 、sys_connect_by_path。
　　浅谈oracle树状结构层级查询的博客地址是 浅谈oracle树状结构层级查询之start with ....connect by prior、level及order by
　　下面试测试数据：
　　创建表：

(
  dept_id         VARCHAR2(32) not null,
  dept_name       VARCHAR2(128),
  dept_code       VARCHAR2(32),
  par_dept_id     VARCHAR2(32),
  dept_leader     VARCHAR2(32),
  dept_desc       VARCHAR2(256),
  create_time     CHAR(19),
  org_id          VARCHAR2(32),
  dept_type       VARCHAR2(1),
  order_id        NUMBER,
  state           CHAR(1) default ‘1‘,
  bqq_dept_id     VARCHAR2(128),
  bqq_par_dept_id VARCHAR2(128)
)
