SQL 导入导出Excel数据的语句

--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
