用于多个 Excel 文件加载的 SQL Server 存储过程

如何解决用于多个 Excel 文件加载的 SQL Server 存储过程

请帮我看看他们的程序是否可用于将多个 Excel 文件加载到 sql Server 表中。

我在谷歌上找到了一个，但没有按预期工作：

消息 111，级别 15，状态 1，过程 usp_ImportMultipleFiles，第 11 行 [批处理开始第 40 行]
“CREATE/ALTER PROCEDURE”必须是查询批处理中的第一条语句。

必须声明标量变量“@filepath”。

解决方法

我在这里看到两个错误：

'CREATE/ALTER PROCEDURE' 必须是查询批处理中的第一条语句。

必须声明标量变量“@filepath”。

获取一个非常简单的脚本来工作，然后在此基础上进行构建。可以这样试试吗？

insert into test.dbo.Categories
SELECT * FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0','Excel 12.0;
Database=C:\Users\Excel\Desktop\Book1.xls;
HDR=yes','Select * from [Sheet1$]')
