从SQL Server中导入导出Excel的基本方法1

从SQL Server中导入/导出excel 的基本方法/*=========== 导入/导出excel 的基本方法===========*/从excel文档中,导入数据到sql数据库中,直接用下面的语句:/*=============================================*/--假如接受数据导入的表已存在insert into 表select * fromopenrowset(microsoft.jet.oledb.4.0,excel 5.0;hdr=yes;database=c:test.xls,sheet1$)--假如导入数据并生成表select * into 表fromopenrowset(microsoft.jet.oledb.4.0,excel 5.0;hdr=yes;database=c:test.xls,sheet1$)/*===========================================*/--假如从sql数据库中,导出数据到excel,假如excel文档已存在,而且已按照要接收的数据创建好表头,就能够简单的用:insert into openrowset(microsoft.jet.oledb.4.0,excel 5.0;hdr=yes;database=c:test.xls,sheet1$)select * from 表--假如excel文档不存在,也能够用bcp来导成类excel的文档,注意大小写:--导出表的情况exec master..xp_cmdshell bcp 数据库名.dbo.表名out "c:test.xls" /c -/s"服务器名" /u"用户名" -p"密码"--导出查询的情况exec master..xp_cmdshell bcp "select au_fname, au_lname from pubs..authors order by au_lname" queryout "c:test.xls" /c -/s"服务器名" /u"用户名" -p"密码"/*--说明:c:test.xls 为导入/导出的excel文档名.sheet1$ 为excel文档的工作表名,一般要加上$才能正常使用.--*/--上面已说过,用bcp导出的是类excel文档,其实质为文本文档,--要导出真正的excel文档.就用下面的方法/*--数据导出excel导出表中的数据到excel,包含字段名,文档为真正的excel文档,假如文档不存在,将自动创建文档,假如表不存在,将自动创建表基于通用性考虑,仅支持导出标准数据类型--邹建2003.10--*//*--调用示例p_exporttb
