并排列合并

Question

我需要创建一个价格比较工具，所以这样的需求来了。为此，我从数据库查询中得到了两个不同的结果集。我的数据库是 SQL Server 2017 Developer Edition。我想要的是并排合并两个结果集。见下图：

我的查询

SELECT ADuration Duration, APlan_Price AmazonPrice 
FROM tbl_AmazonPlans
WHERE AProduct_Name = 'Air Conditioner'
  AND 14678 BETWEEN TRY_CONVERT(int, PARSENAME(REPLACE(APrice_Range, '-', '.'), 2))
                AND TRY_CONVERT(int, PARSENAME(REPLACE(APrice_Range, '-', '.'), 1))

SELECT Duration, Plan_Price GwPrice
FROM tbl_PlanDetails
WHERE Product_Name = 'Air Conditioner'
  AND 14678 BETWEEN TRY_CONVERT(int, PARSENAME(REPLACE(Price_Range, '-', '.'), 2))
                AND TRY_CONVERT(int, PARSENAME(REPLACE(Price_Range, '-', '.'), 1))

来自表 may/may 的结果集不具有相同的架构。也没有连接点，因为它们没有公共键。但是，是的，它们包含一些可能相同的列，并且基于这些相同的列，我必须获得预期的结果集。

Answer 1

Duration 列是两个表中共同的标识符吗？如果是，那么你可以使用内部连接。

select
    Duration,
    APlan_Price as AmazonPrice
    Plan_Price as GwPrice
from tbl_AmazonPlans
inner join tbl_PlanDetails on tbl_PlanDetails.Duration = tbl_AmazonPlans.Duration
where /* Your filter here */

Answer 2

您可以直接加入表格，但如果您的 where 标准可能不同以保持简单，您可以直接加入结果集

select a.duration, a.AmazonPrice, b.GwPrice
from (
    Select ADuration Duration, APlan_Price AmazonPrice 
    From tbl_AmazonPlans
    Where AProduct_Name ='Air Conditioner'
    and 14678 between try_convert(int,parsename(replace(APrice_Range,'-','.'),2))
                                and try_convert(int,parsename(replace(APrice_Range,'-','.'),1))
)a
join
(
    Select Duration, Plan_Price GwPrice
     From tbl_PlanDetails
     Where Product_Name ='Air Conditioner'
    and 14678 between try_convert(int,parsename(replace(Price_Range,'-','.'),2))
                                and try_convert(int,parsename(replace(Price_Range,'-','.'),1))
)b on a.duration = b.duration
