我有 2 个选择返回 2 个表，在每个表中我有 12 行和 2 列，现在我只想有一个表。

---- First Table
    select f. date as Date, f.value as Month1 
        from
            (
                select b.date as date, sum(b.value) as value
                from business bu
                    join bus_cat buc on buc.id = bu.id
                    join cat ct on ct.id = buc.type_id
                    join bus2 b on b.id = buc.id
                where ct.id = 1
                    and b.value <> 0
                    and b.date between @start and @actual
                    and bu.name = @bu_name
                group by b.date, b.value

                union all

                select b5.date as date, sum(b5.value) as value
                from bus bu
                    join bus_cat buc on buc.id = bu.id
                    join cat ct on ct.id = buc.type_id
                    join bus3 b5 on b5.id = buc.id
                where ct.id = 1
                    and b5.value <> 0
                    and b5.date between @nextM and @endM
                    and bu.name = @bu_name
                group by b5.date, b5.value

            ) as f


---- Second Table   

        select f1. date as Date, f1.value as Month2 
        from
            (
                select b.date as date, sum(b.value) as value
                from business bu
                    join bus_cat buc on buc.id = bu.id
                    join cat ct on ct.id = buc.type_id
                    join bus2 b on b.id = buc.id
                where ct.id = 1
                    and b.value <> 0
                    and b.date between @start and @actual
                    and bu.name = @bu_name
                group by b.date, b.value

                union all

                select b5.date as date, sum(b5.value) as value
                from bus bu
                    join bus_cat buc on buc.id = bu.id
                    join cat ct on ct.id = buc.type_id
                    join bus3 b5 on b5.id = buc.id
                where ct.id = 1
                    and b5.value <> 0
                    and b5.date between @nextM and @endM
                    and bu.name = @bu_name
                group by b5.date, b5.value

            ) as f1

第一个表的实际输出是：

Date                Month1
2015-01-01        23
2015-01-01        77

第二：

Date                Month2
2015-01-01        88
2015-01-01        90

我想要的只是合并这两个表看起来像

   Date                Month1      Date                Month2
    2015-01-01        23         2015-01-01             77          
    2015-01-01        28         2015-01-01             787

正如我在评论中所说，一个简单的连接应该可以解决问题。就像是：

SELECT      *
FROM        
            (
                select b.date as date, sum(b.value) as value
                from business bu
                    join bus_cat buc on buc.id = bu.id
                    join cat ct on ct.id = buc.type_id
                    join bus2 b on b.id = buc.id
                where ct.id = 1
                    and b.value <> 0
                    and b.date between @start and @actual
                    and bu.name = @bu_name
                group by b.date, b.value

                union all

                select b5.date as date, sum(b5.value) as value
                from bus bu
                    join bus_cat buc on buc.id = bu.id
                    join cat ct on ct.id = buc.type_id
                    join bus3 b5 on b5.id = buc.id
                where ct.id = 1
                    and b5.value <> 0
                    and b5.date between @nextM and @endM
                    and bu.name = @bu_name
                group by b5.date, b5.value

            ) as f
LEFT JOIN   (
                select b.date as date, sum(b.value) as value
                from business bu
                    join bus_cat buc on buc.id = bu.id
                    join cat ct on ct.id = buc.type_id
                    join bus2 b on b.id = buc.id
                where ct.id = 1
                    and b.value <> 0
                    and b.date between @start and @actual
                    and bu.name = @bu_name
                group by b.date, b.value

                union all

                select b5.date as date, sum(b5.value) as value
                from bus bu
                    join bus_cat buc on buc.id = bu.id
                    join cat ct on ct.id = buc.type_id
                    join bus3 b5 on b5.id = buc.id
                where ct.id = 1
                    and b5.value <> 0
                    and b5.date between @nextM and @endM
                    and bu.name = @bu_name
                group by b5.date, b5.value

            ) as f1
        ON  f.date = f1.date

顺便说一句，这个查询可以简化，看起来查询中有很多相似之处。
