我已经成功地为自己构建了一个漂亮的小 T-SQL 语句，它将调度信息转换为每月的列。

SELECT *
FROM 
(
    SELECT 
    t1.customer_code,
    t1.part_number,
    LEFT(DATENAME(month, [formatted_date]),3) as [Month],
    t1.quantity as [quantity] FROM FORECAST_VIEW as t1

    where
        quantity <> 0 
        and formatted_date >= DATEADD(month, DATEDIFF(month, 0, GETDATE()), 0)  

) as p
pivot
(
    sum(quantity)
    for [Month] in (Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec)
) as p
order by customer_code, part_number

这会产生一个带有列的输出

customer_code, part_number, Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec

并汇总每个月所需的 part_number 数量。

这工作正常并且在报告中产生奇迹，但是如果我可以让月份列从当前月份开始并按顺序排列 …
