sql - 存储过程的语法错误

Question

环境：SQL Server 2008 R2。

这是一个由 APP 调用的存储过程，用于将数据从一组表从数据库复制到另一个数据库，其中它们都具有相同的模式。它似乎没有复制数据。当我尝试在查询分析器上手动运行它时。

exec dbo.sp_Copy_DB_Subset_Tables ('Server1\Instance','MainDB','Server1\Instance','MiniDB')

但是当我运行它时出现此错误：

消息 102，级别 15，状态 1，第 1 行
'Server1\Instance' 附近的语法不正确。

这是存储过程，我看不出这怎么会出错。数据库位于同一台服务器上。为什么我会收到错误消息？

Answer 1

exec dbo.sp_Copy_DB_Subset_Tables 'Server1\Instance','MainDB','Server1\Instance','MiniDB'

不带括号试试？
