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
