,也许您可以张贴到目前为止已编写的代码.它将帮助我们提供最后一步.

您不能在枢轴中将case语句与聚合函数一起使用.
请参考以下URL:-http://technet.microsoft.com/zh-cn/library/ms177410.aspx
如果要使用case语句,则可以在使用了ivot关键字的实际select语句中使用.检查以下语法:-
SELECT``Sun''=
如果[Sun]> 0则为"true",否则为"false"结束,
``星期一''=
[Mon]> 0时为"true",否则为"false"的情况,
``Tue''=
[Tue]> 0时为"true",否则为"false"结束的情况

(选择
天数,费用
来自

)P
PIVOT(
总和(费用)
FOR
天数
(
[Sun],
[星期一],
[Tue]
))AS PVT
这样,您可以在查询中使用case语句. :)

Hi,
you can not use case statement along with aggregate function in pivot.
refer the following URL :- http://technet.microsoft.com/en-us/library/ms177410.aspx
If you want to use case statement then you can use in actual select statement in which you have used pivot keyword. check the following syntax:-
SELECT ''Sun''=
case when [Sun]>0 then ''true'' else ''false'' end,
''Mon'' =
case when [Mon]>0 then ''true'' else ''false'' end,
''Tue'' =
case when [Tue]>0 then ''true'' else ''false'' end
FROM
(Select
Days, Cost
From
Product
)P
PIVOT(
Sum(Cost)
FOR
Days IN
(
[Sun],
[Mon],
[Tue]
)) AS PVT
This way you can use case statement in your query. :)
Thanks
