动态Sql方法

IF OBJECT_ID('Tempdb..##Months')IS NOT NULL
DROP TABLE ##Months

SELECT number,
        DATENAME(MONTH,DATEADD(MONTH ,number-DATEPART(MONTH,GETDATE()),GETDATE())) AS Months
        INTO ##Months

Answer 2

您要取消枢轴旋转。我会这样做：

select t.o, v.category,
       max(case when t.p = 'January' then v.val end) as jan,
       max(case when t.p = 'February' then v.val end) as feb,
       . . .
       max(case when t.p = 'December' then v.val end) as dec
from t cross apply
     (values ('a', a), ('b', b), . . . ('n', n)
     ) v(category, val)
group by t.o, t.p;

取消枢纽与多栏
