SELECT * FROM T_UFW_INFO_CATEGORY START WITH NUMBER_CATEGORY=\'01-03-02-09\' CONNECT BY PRIOR PARENT_ID = ID

查询当前节点及其所有父节点。

   ID                   VARCHAR2(30)                    not null,
   NAME                 VARCHAR2(200),
   NUMBER_CATEGORY      VARCHAR2(30),
   PARENT_ID            VARCHAR2(30),
   LEVEL_INFO           VARCHAR2(10),
