Question

我想根据PIVOT函数生成的列按函数应用group。

在下面的查询中，我想应用Sum（TC.MB_Usage），所以我最后可以使用group by。但是，我无法将按功能分组应用于由PIVOT功能（SITES）生成的列。

BOLD

中提到了评论

Answer 1

您需要在GROUP BY中指定各个列。

您的SITES别名看起来将具有IMSI，MDN，IMSI_MDN列，然后是PIVOT子句中的1,2,3,4,5,6,7,8,9,10,11,12,13

因此，请尝试单独列出这些内容，对于数字内容，请使用引号将其括起来：

GROUP BY
...
SITES."1", SITES."2", etc.

对于数据透视表列，需要按
