在组合两个查询时多次重复相同的值

Question

我在执行空洞查询时在mysql workbench中写了两个查询，我得到了相同的值。我该怎么办？

这是我的查询

Select * 
from 
  (
    (select division.name,
            date(meter_data.reading_date),
            sum(meter_data.meter_delta) 'Gas Consumption (m3)'
     from meter, meter_data, division
     where meter.meter_id = meter_data.meter_id 
       and meter.division_id = division.division_id
       and Date(meter_data.reading_date) between '2018-04-01' and '2018-05-03' 
     group by date(meter_data.reading_date) 
    ) as table1,

    (Select Date(receipt.receipt_date), 
            sum(case receipt_item.item_name 
                    when 'Gas' then receipt_item.item_amount else 0 
                end) 'Gas Purchase'
     from receipt_item, receipt
     where receipt.receipt_id = receipt_item.receipt_id
       and Date(receipt.receipt_date) between '2018-04-01' and '2018-05-03'  
     group by Date(receipt.receipt_date)
    ) as table2
  );

在单独执行查询时，每个查询返回精确的33个但总共返回1089个rwos

例如我在这里得到的所有重复的相同数据

但需要像那样展示（这个是演示图片）
