oracle設定菜單全路徑

1、首先設定一級菜單的full_name(全路徑)

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

2、設定二級菜單的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 ,  -- 獲取二級菜單
             (select * from S_DEPARTMENT where dep_level = '1') b    -- 獲取一級菜單
             where a.fid = b.id
)
set full_name = cc||'/'||dep_name ;
