此sql语句中的PIVOT错误

Question

我有这张桌子

CUSTOMERNAME |  PRODUCTNAME  |  AMMOUNT
=======================================
Customer1       Product1         10
Customer1       Product1         100
Customer2       Product2         20
Customer2       Product2         200
Customer1       Product2         30
Customer1       Product2        300
Customer2       Product1         40
Customer2       Product1        400

我需要这张桌子：

Product1      |  Product2       .|.. ProductN
=================================
Sum(ammount)       Sum(Ammount)  |   Sum(Ammount)

我尝试了什么

我明白我需要使用PIVOT。

这是我的尝试

Selectt temp.Product1, temp.Product2
FROM
(
select ProductName, Ammount
from CustomerProducts
)
PIVOT(
  SUM(Ammount)
  FOR ProductName IN (['Product1'])
) as temp

这是我的例外

Incorrect syntax near '.'.: Selectt temp.Product1, temp.Product2 FROM ( select ProductName, Ammount from CustomerProducts ) PIVOT( SUM(Ammount) FOR ProductName IN (['Product1']) ) as temp

SQL FIDDLE

Answer 1

删除单引号，并包括您想要转动的所有产品，应该只是FOR ProductName IN（[Product1]，[Product2]），您还需要为子查询添加别名。您还在selectt中添加了两个ts。

进行最终查询：

SELECT  temp.Product1, temp.Product2
FROM    (   SELECT  ProductName, Ammount
            FROM    CustomerProducts
        ) AS c -- SUBQUERY ALIAS HERE
        PIVOT
        (   SUM(Ammount)
            FOR ProductName IN ([Product1], [Product2]) -- REMOVE SINGLE QUOTES, INCLUDE ALL PRODUCTS
        ) AS temp;
