【中文标题】用于多个 excel 文件加载的 SQL Server 存储过程 [关闭]

【英文标题】：SQL Server Stored Procedure for multiple excel file load [closed]

【问题描述】：

请帮助我，他们的程序可用于将多个 Excel 文件加载到 SQL Server 表中。

我在 google 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。

消息 137，第 15 级，状态 2，第 67 行 必须声明标量变量“@filepath”。

1a。创建用于获取文件名的表

【问题讨论】：

错误告诉你这里的问题："CREATE/ALTER PROCEDURE' must be the first statement in a query batch." 你为什么使用动态 SQL 来创建程序在这里？特别是当动态语句无效时。

旁注：您为什么在其中一些列中使用float？例如，何时需要将某人工作的小时数存储为浮点值？您是否真的告诉人们，例如您上周工作了 0.375×10^2 小时？

【参考方案1】：

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$]')
