【问题描述】：

我正在尝试重命名 SQL Server 中的数据透视列，即

for days in ([22], [23], [24], [25], [26], [27], [28]

有没有办法做到这一点？

这是我的查询：

select *
from 
    (select
         day(date) as days,
         temp 
     from 
         temperature) as t
pivot
    (max(temp) 
        for days in ([22], [23], [24], [25], [26], [27], [28])
    ) as pivot_table

【问题讨论】：

rename pivot columns 到底是什么意思？您是指结果中的列吗？

是的，我想将列从整数 22 重命名为二十二，从 23 重命名为二十三，依此类推。

SELECT [22] as [twenty-two], [23] as [twenty-three], . . .

【参考方案1】：

正如松鼠推荐的那样：

select [22] as [twenty-two], [23] as [twenty-three] ...
from (
    select
         day(date) as days,
         temp 
    from temperature) as t
pivot(max(temp) 
      for days in ([22], [23], [24], [25], [26], [27], [28])
) as pivot_table
