Sql 将2个CTE和多个选择组合到一个查询中

我在尝试将这两个CTE合并到一个查询中时遇到困难。有人能帮我指引正确的方向吗？我尝试在第一个CTE之后使用逗号，并删除第二个CTE中的“WITH”，但不确定将括号放在何处，因此出现错误：

消息156，级别15，状态1，第33行关键字附近语法不正确 “选择”。Msg 102，15级，状态1，第48行附近语法不正确

样本数据：

IIUC-考虑将RoWo数查询拆分为它们各自的CTE，然后运行选择“区别为最终语句”。现在，您调用内部的CTE，导致递归，而这似乎不是您所需要的。下面将分解两个结果集：

在第一列之前添加半列：；具有在第二个拷贝之后，从第一个拷贝之前的半列中选择*；有了……就不是了；使用@zip。仅凭一句话是正确的。这个在语句的末尾，而不是开始处。我明白了，虽然在Dee之前您有一些代码没有显示给我们，但是我的badI仍然得到一个公共表表达式的递归成员“ANS_CTE”有多个递归引用。在第二次CTE结束时，关于从ANS_CTE中选择*我该怎么做？您试图实现什么？请包括样品数据和预期结果。这是一个不完整的SQL查询。定义CTE后必须有一个最终语句。在第一个前添加一个半列：；具有在第二个拷贝之后，从第一个拷贝之前的半列中选择*；有了……就不是了；使用@zip。仅凭一句话是正确的。这个在语句的末尾，而不是开始处。我明白了，虽然在Dee之前您有一些代码没有显示给我们，但是我的badI仍然得到一个公共表表达式的递归成员“ANS_CTE”有多个递归引用。在第二次CTE结束时，关于从ANS_CTE中选择*我该怎么做？您试图实现什么？请包括样品数据和预期结果。这是一个不完整的SQL查询。定义CTE后必须有最终声明。
