我有一张这样的桌子...
I have a table like this...
CustomerID DBColumnName Data
--------------------------------------
1 FirstName Joe
1 MiddleName S
1 LastName Smith
1 Date 12/12/2009
2 FirstName Sam
2 MiddleName S
2 LastName Freddrick
2 Date 1/12/2009
3 FirstName Jaime
3 MiddleName S
3 LastName Carol
3 Date 12/1/2009
我想要这个...
这可以使用 PIVOT 吗?
Is this possible using PIVOT?
CustomerID FirstName MiddleName LastName Date
----------------------------------------------------------------------
1 Joe S Smith 12/12/2009
2 Sam S Freddrick 1/12/2009
3 Jaime S Carol 12/1/2009
您可以使用 MAX 聚合,它仍然可以工作.一个值的最大值 = 该值..
You can use the MAX aggregate, it would still work. MAX of one value = that value..
在这种情况下,您也可以在 customerid 上自行加入 5 次,按每个表引用按 dbColumnName 过滤.可能效果会更好.
In this case, you could also self join 5 times on customerid, filter by dbColumnName per table reference. It may work out better.
这篇关于没有聚合函数的 TSQL Pivot的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
