Oracle父节点及其子节点数据的查询

Oracle语句如下：

使用方法：start with.....connect by prior。其中start with后面跟的条件1是父节点的查询条件，connect by prior后面跟的条件2是与记录的父节点相同的子节点中的数据。

示例：

SELECT id,
       name as text,
       parent_id as parentId
  from TF_SYS_T_ACTION action
 where 1 = 1
   and action.id in (select caction.action_id
                       from TF_SYS_T_CUSTOMERACTION caction
                      where caction.cust_domain = '110108')
 START WITH parent_id = '0'
CONNECT BY PRIOR id = parent_id
