--从Excel文件中,导入数据到SQL数据库中,很简单,直接用下面的语句:
/*===================================================================*/
--如果接受数据导入的表已经存在
insert into 表 select * from
OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
,'Excel 5.0;HDR=YES;DATABASE=c:\test.xls',sheet1$)
--如果导入数据并生成表
select * into 表 from
OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
,'Excel 5.0;HDR=YES;DATABASE=c:\test.xls',sheet1$)

/*===================================================================*/
--如果从SQL数据库中,导出数据到Excel,如果Excel文件已经存在,而且已经按照要接收的数据创建好表头,就可以简单的用:
insert into OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
,'Excel 5.0;HDR=YES;DATABASE=c:\test.xls',sheet1$)
select * from 表

--如果Excel文件不存在,也可以用BCP来导成类Excel的文件,注意大小写:
--导出表的情况
EXEC master..xp_cmdshell 'bcp 数据库名.dbo.表名 out "c:\test.xls" /c -/S"服务器名" /U"用户名" -P"密码"'
--导出查询的情况
EXEC master..xp_cmdshell 'bcp "SELECT au_fname, au_lname FROM pubs..authors ORDER BY au_lname" queryout "c:\test.xls" /c -/S"服务器名" /U"用户名" -P"密码"'
/*--说明:
c:\test.xls 为导入/导出的Excel文件名.
sheet1$ 为Excel文件的工作表名,一般要加上$才能正常使用.
--*/

--下面是导出真正Excel文件的方法:
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
