1，业务说明：

报表查询数据,第一列要查询A类型数据,第二列要查询B类型数据(如A1.jpg)

2，sql：

SELECT 日期, 类型, 温度, 数量, company
  from ((select trunc(a.estimate_date, 'dd') as 日期,
                a.name as 类型,
                a.category as 温度,
                sum(a.moved_quantity_bu) as 数量,
                a.company_id as company
           from A a
          group by trunc(a.estimate_date, 'dd'),
                   a.name,
                   a.category,
                   a.company_id) union all
        (select trunc(b.intend_ship_date, 'dd') as 日期,
                '出库单' as 类型,
                b.category as 温度,
                sum(b.shipped_quantity_bu) as 数量,
                b.company_id as company
           from B b
          group by trunc(b.intend_ship_date, 'dd'), b.category, b.company_id))
 WHERE trunc(日期, 'dd') >= ?
   and trunc(日期, 'dd') <= ?
   and company = ?
 ORDER BY 日期, 温度
