SQL EXEC PROCEDURE：“必须声明标量变量“@p1”

Question

当我尝试执行下面的存储过程时出现以下错误：

Must declare the scalar variable "@p1"

我不明白为什么或如何解决，任何帮助将不胜感激。谢谢

编辑：使用 sql server 2014。这不是我的代码，我正在尝试修复其他人代码中的错误。

更新：更新了“执行命令”部分以显示过程是如何执行的

如果要在动态语句中使用参数，则需要使用sp_executesql 而不是EXEC()：

    @p1 nvarchar(100),  
    @n nvarchar(100)

    SET @stm =
