我列出了一些数据，如附件图片

SELECT Code, compCode FROM KitItems

数据当前的格式如下：

但我希望将其转置为许多列

Answer 1

您可以使用row_number()并进行条件聚合：

select code, 
       max(case when seq = 1 then compcode end) as one,
       max(case when seq = 2 then compcode end) as two,
       . . .
       max(case when seq = 7 then compcode end) as seven
from (select t.*,
             row_number() over (partition by code order by compcode) as seq
      from table t
     ) t
group by code;

如果PIVOT有太多的code，则可以通过动态compcode SQL实现相同的目的。
