多次引用 CTE 时对象名称无效

【问题标题】：Invalid Object Name When Referencing CTE Multiple Times多次引用 CTE 时对象名称无效
【发布时间】：2023-03-31 20:39:01
【问题描述】：

我在运行下面的代码时收到以下错误消息，但我不明白为什么。该代码构建了两个链式 CTE，然后针对它们运行 SELECT 语句。

    【解决方案1】：

    CTE 只能由紧随其后的 SELECT 语句引用。在您的情况下，FFCSource CTE 由其后的两个 SQL 语句引用。它适用于第一个 SELECT，然后当它到达第二个时抛出此错误。

    如果需要在多个查询中引用CTE，则重构，将FFCSource的结果写入临时表，或者表变量，然后引用this。

    试试这样的...
