- 1、在SQL数据库中直接从Excel里面查询数据:
- select * from
- OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
- ,'Excel 5.0;HDR=YES;DATABASE=c:\test.xls',sheet1$)
- 2、从Excel文件中,导入数据到SQL数据库中,
- select * into 表 from
- OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
- ,'Excel 5.0;HDR=YES;DATABASE=c:\test.xls',sheet1$)
- 3、从SQL数据库中,导出数据到Excel(excel存在),
- insert into OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
- ,'Excel 5.0;HDR=YES;DATABASE=c:\test.xls',sheet1$)
- select * from 表
- 4、从SQL数据库中,导出数据到Excel(excel不存在),
- ---- 导出表
- EXEC master..xp_cmdshell 'bcp 数据库名.dbo.表名 out "c: est.xls" /c -/S"服务器名" /U"用户名" -P"密码"'
- ---- 导出查询语句
- EXEC master..xp_cmdshell 'bcp "Select au_fname, au_lname FROM pubs..authors orDER BY au_lname" queryout "c: est.xls" /c -/S"服务器名" /U"用户名" -P"密码"'
- 5、导入导出的存储过程
- --下面是导出真正Excel文件的方法:(请将一下所有代码复制到存储过程中)
- if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[p_exporttb]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
- drop procedure [dbo].[p_exporttb]
- GO
- /**//*--数据导出EXCEL
- 导出表中的数据到Excel,包含字段名,文件为真正的Excel文件
- ,如果文件不存在,将自动创建文件
- ,如果表不存在,将自动创建表
- 基于通用性考虑,仅支持导出标准数据类型
