用于报告的SQL多行到多列（所需列数未知）

我已经搜索了许多非规范化和多行到多列的帖子，但似乎没有一个能满足我的要求

我有一个具有重复ID的表，在其他字段中具有不同的值。根据关联记录的数量，ID可以有1-20行

例如：

Input - 
ID  Name    Address
1   A         A1
1   B         A2
1   C         A3
1   C         A4

Output - 
ID  Name1   Address1    Name2   Address2    Name3   Address3    Name4   Address4
1   A         A1          B       A2          C       A3          C        A4

我写了一些非常难看的SQL，在插入之前检查每个字段，但我希望有一种更干净的方法，因为这对更改非常不灵活。任何想法

一旦您获得结果，您将如何使用这些结果？您是否考虑过返回具有相同ID的所有数据的组？（即，按功能分组）光标可能是正确的选择？我可能完全没有把握，但听起来像是那种问题。乔-我实际上是在用光标填充变量，然后我需要取这些变量，看看第一组列是否已填充。如果是，请转到第二组columns.Taraz-我正在创建一个表，其中一行基于ID，然后在报告中使用此数据。因此，每组列将在报告中的一行上生成。这有点像我必须对表进行非规范化以使其规范化报表。我在上面添加了输出示例！
