我在 Stack Overflow 上看到了几篇文章，描述了如何在 SQL Server 存储过程中使用动态列，但我的尝试导致出现有关我尝试使用的动态列名称的错误消息。
消息 245，级别 16，状态 1，过程 sp_FetchBrandImagesNoCatID，第 21 行 [批量开始行 2]
将 varchar 值“share_on_macy”转换为数据类型 int 时转换失败。
当我不尝试引用动态列名时，存储过程工作正常，只有当我添加使用动态列名时才会出现错误（我使用的是 SQL Server 2014）。
这是存储过程：尝试使用传递给存储过程的列名

当我从 SQL Server Management Studio“执行存储过程”调用存储过程时，我在提供的对话框中提供了 5 个参数，然后按“确定”，然后收到错误。
我一定错过了一些明显的东西，如果是这样，我提前道歉，但这是我第一次尝试在存储过程中使用动态列名，我很感激任何帮助！
感谢您的有用建议 - 我已经学到了很多东西:) 解决方案是声明一个变量字符串来包含整个查询，从而允许灵活使用传递的参数：
