Question

我正在SQL Server中的一个项目上工作，我需要查找多少订单包含多个产品。例如，订单号为1，对于样式a，它有多个记录1，对于样式b，它有一个记录。我需要找出同时包含两种样式（a和b或a和c）的订单

select distinct(ordernumber), Style
from table1
join table2 on join1 = join1
where Style in ('a','b','c')
order by ordernumber

我希望将数据导入Excel进行分析，并查看包含我所讨论组合的订单数量。

ordernumber     style
1                 a
1                 b
2                 c
2                 a

我想看看有多少订单具有多种样式。

您需要首先查找具有多个产品的订单号，然后查找所有这些订单ID的详细信息。您可以检查以下脚本-

SELECT * FROM Table1 A
INNER JOIN table2 B ON A.<Joining Column> = B.<Joining Column>    
WHERE A.ordernumber IN
( 
    --This query will return Order Numbers that have at least
    --2 style in the order details table
    SELECT C.ordernumber
    FROM table1 C
    INNER JOIN table2 D ON C.<Joining Column> = D.<Joining Column>
    WHERE Style IN ('a','b')
    GROUP BY C.ordernumber
    HAVING COUNT(DISTINCT Style) = 2

    UNION

    SELECT C.ordernumber
    FROM table1 C
    INNER JOIN table2 D ON C.<Joining Column> = D.<Joining Column>
    WHERE Style IN ('a','C')
    GROUP BY C.ordernumber
    HAVING COUNT(DISTINCT Style) = 2
)
