SQL server 2005中PIVOT附近的语法不正确

我想在透视表中创建SSRS报告。所以我写了下面的问题。 在分析下面的查询时，我发现Pivot错误附近的语法不正确

Create PROCEDURE [dbo].[CP_get_transaction_by_card_Type_Summary]

@EndDate DateTime

有谁能帮我找出上面查询中的错误吗？

您在T中的选定列中添加了聚合和，但在前两列中没有添加聚合和，即SalesChannel和CardType。错误是因为pivot的源表T不正确。

您在T中的选定列中添加了聚合和，但在前两列（即SalesChannel和CardType）中没有添加。错误是因为pivot的源表T不正确。此查询是否独立工作？您收到的错误消息是什么？如果在不使用PIVOT的情况下运行子查询，是否会出现错误？我已删除聚合函数sum，但仍然会出现相同的错误-
