Dynamic Pivot

。您是否有类似于我希望结果集的示例？您正在寻找透视表。在这里搜索

[sql server]行到列

很好的示例-唯一的问题是他说将有10个电话号码字段，因此您希望将计数器硬编码为10，而不是动态获取它。但是预期结果不会显示所有10个电话号码。不管如何，如果最多可以有10个号码，然后我们可以安全地假设他的新表（数据最有可能出现的地方）将有10个电话号码列。他有10个电话号码，我不知道-为什么他不创建一个连接表来存储它们，我也不知道（特别是在经历了这一次混乱之后）。到目前为止，这是最好的答案。很不错的！唯一的问题是，问题说明最多可以有10个电话号码，因此您需要编辑答案以包含所有10个。@StanShaw正在处理动态版本，因此电话号码字段的数量将不会是一个已发布动态版本的问题。然而，这是行不通的，因为他需要一个有10个电话号码的表。@StanShaw刚刚发布了动态版本
