【问题描述】：

我有以下查询。我需要将销售代表列为列，并在相应的销售代表下的 DESCRIP 中列出信息。 Pivot 不起作用，因为我没有汇总任何内容。还没有找到与我有关的内容，因此我正在寻求您的帮助。感谢您的宝贵时间。

DLI01...      MIT01...      NUS01...
KID01...      DLI01...      LIM01...

【参考方案1】：

嗯。 . .我想你想要：

select max(case when sales_rep = 'AG' then col end) as ag,
       max(case when sales_rep = 'BD' then col end) as bd,
       . . . 
from (select t.*, row_number() over (partition by sales_rep, col order by col) as seqnum
      from t cross apply
           (values (substring(descr, 2, 5))) v(col)
     ) t
group by seqnum;

【讨论】：

如果销售代表的数量发生变化怎么办？更多的是一种动态方式，因此他们不必每次都更改查询？感谢您的回复。

@Mark 。 . .如果您不知道销售代表列表先验，则必须动态构建查询。
