在SQL中将多行显示为不同的列

我有以下查询，显示同一产品但不同销售状态的不同行中的产品列表：

select distinct productname as 'Product', sale_status as 'Sold/Unsold', count(distinct i.item_number) as 'Total Items'
            from item i
            left join department d on i.item_number = d.item_number
            where d.term = 'WINTER' and d.year = '2014'
            group by productname,sale_status
            order by productname

其输出为：

       Product       Sold/Unsold        Total Items
        Bags            SOLD                 20
        Bags            UNSOLD              100
        Shoes           SOLD                 30
        Shoes           UNSOLD               50

       Product         SOLD        UNSOLD        Total Items
        Bags            20          100             120
        Shoes           30           50              80

现在我需要将输出显示为：

       Product       Sold/Unsold        Total Items
        Bags            SOLD                 20
        Bags            UNSOLD              100
        Shoes           SOLD                 30
        Shoes           UNSOLD               50

       Product         SOLD        UNSOLD        Total Items
        Bags            20          100             120
        Shoes           30           50              80

我尝试使用PIVOT来完成以下任务，但我无法实现此目标。它说：关键字“PIVOT”附近的语法不正确

select distinct productname as 'Product', sale_status as 'Sold/Unsold', count(distinct i.item_number) as 'Total Items'
            from item i
            left join department d on i.item_number = d.item_number
            where d.term = 'WINTER' and d.year = '2014'
            group by productname,sale_status
            order by productname
            PIVOT
            (
            SUM (Total Items)
            FOR [Sold/Unsold] IN ([SOLD], [UNSOLD])
            ) as P

有什么建议或任何其他可能的方法来实现这一目标吗？

将当前查询放在子查询中，然后围绕子查询旋转

SELECT  Product, 
    [SOLD], 
    [UNSOLD], 
    [SOLD] + [UNSOLD] AS [Total Items] 
FROM
(
    SELECT DISTINCT
        productname AS [Product],
        sale_status AS [Sold/Unsold],
        COUNT(DISTINCT i.item_number) AS [Total Items]
    FROM
        item i
        LEFT JOIN department d ON i.item_number = d.item_number
    WHERE
        d.term = 'WINTER'
        AND d.year = '2014'
    GROUP BY
        productname,
        sale_status
) T
PIVOT 
(
    SUM([Total Items])
    FOR [Sold/Unsold] IN ([SOLD],[UNSOLD])
) p

Total Items

是一个列名。它不应该有空间分隔。用户

“项目总数”

instead@vkp你的意思是应该在单引号

“

？@Juan.字符串的单引号之间。这是一个列。我尝试了单引号或双引号，但仍然会出现错误“关键字“PIVOT”附近的语法不正确”。它需要放在方括号中……或者更好的是，从派生列名中去掉空格。列名中的空格只会给代码增加不必要的复杂性。
