考虑MySQL数据透视表吗？

这是我能得到的最好的…如何合并相同的fromP和toP？如果使用group by只能显示单元格上升或下降

在where子句后添加group by，那么让我们说在toP

group by T.toP

不确定@Kumar为什么删除了他们的答案。在我看来差不多是对的。

SELECT T.fromP,T.toP,T.value,T.type FROM CELLPROPERTYFACT F 
INNER JOIN DIM_TIMING T ON T.timingID = F.timingID 
WHERE T.cellID = '1' 
AND (type = 'cell_rise' or type = 'cell_fall');

+-------+------+----------+-----------+<br>
