Oracle SQL 连接两个单独的用户生成表

Question

我有一个查询，根据位置的名称显示空位置的数量，我要添加的是我在空位置旁边创建的总位置列，然后我打算做数学显示可用库存空间的百分比。我对子查询等比较陌生，所以我不确定我哪里出错了

完整查询：

select bin_type_name, floor, empty_locations, total day, time from(
    (select bin_type_name,
    bin_level as floor, 
    sum(bin) as empty_locations,
    to_char(sysdate, 'MM-DD-YYYY ') as day,
    to_char(sysdate,'hh:mi:ssam') as time
    from
    (select count(bins.bin_id) as bin, bin_type_name, bin_level
      from bins
      left join bin_items bi on bi.bin_id = bins.bin_id
      where bi.quantity is null
      and usage = '1024'
      group by bins.bin_id, bin_level, bin_type_name)
      group by bin_type_name, bin_level, to_char(sysdate, 'MM-DD-YYYY '), to_char(sysdate,'hh:mi:ssam')
      )order by bin_level) a
      inner join a on a.bin_type_name = b.bin_type_name
    union
    (select bin_type_name, count(bin_type_name) as total, bin_level from bins
    where usage = '1024'
    group by bin_type_name, bin_level
    )order by floor) b;

顶部：

    select bin_type_name, count(b.bin_id) empty_locations, bin_level from bins b
left join bin_items bi on bi.bin_id = b.bin_id
where quantity is null
and usage = '1024'
group by bin_type_name, bin_level, quantity
order by bin_level;

底部

   select bin_type_name, bin_level, count(bin_type_name) as total from bins

其中用法 = '1024' 按 bin_type_name、bin_level 分组 按 bin_level 排序；
