oracle设定菜单全路径

1、首先设定一级菜单的full_name(全路径)

update S_DEPARTMENT t set t.full_name = 'XX集团'  where fid='-1';

2、设定二级菜单的full_name

update (
             select a.dep_name,a.full_name,b.dep_name dd,b.full_name cc from 
             (select * from S_DEPARTMENT where dep_level = '2') a ,  -- 获取二级菜单
             (select * from S_DEPARTMENT where dep_level = '1') b    -- 获取一级菜单
             where a.fid = b.id
)
set full_name = cc||'/'||dep_name ;
