從SQL Server中導入/導出Excel的基本方法

從sql server中導入/導出 excel 的基本方法

/*===========; 導入/導出 excel 的基本方法 ===========*/

從excel文檔中,導入數據到sql數據庫中,很簡單,直接用下面的語句:

/*=============================================*/--假如接受數據導入的表已存在insert into 表 select * from openrowset(microsoft.jet.oledb.4.0,excel 5.0;hdr=yes;database=c:test.xls,sheet1$)

--假如導入數據并生成表select * into 表 from openrowset(microsoft.jet.oledb.4.0,excel 5.0;hdr=yes;database=c:test.xls,sheet1$)

/*===========================================*/--假如從sql數據庫中,導出數據到excel,假如excel文檔已存在,而且已按照要接收的數據創建好表頭,就能夠簡單的用:insert into openrowset(microsoft.jet.oledb.4.0,excel 5.0;hdr=yes;database=c:test.xls,sheet1$)select * from 表

--假如excel文檔不存在,也能夠用bcp來導成類excel的文檔,注意大小寫:--導出表的情況exec master..xp_cmdshell bcp 數據庫名.dbo.表名 out 'c:test.xls' /c -/s'服務器名' /u'用戶名' -p'密碼'

--導出查詢的情況exec master..xp_cmdshell bcp 'select au_fname, au_lname from pubs..authors order by au_lname' queryout 'c:test.xls' /c -/s'服務器名' /u'用戶名' -p'密碼'

/*--說明:c:test.xls; 為導入/導出的excel文檔名.sheet1$;;;為excel文檔的工作表名,一般要加上$才能正常使用.--*/--上面已說過,用bcp導出的是類excel文檔,其實質為文本文檔,

--要導出真正的excel文檔.就用下面的方法

/*--數據導出excel導出表中的數據到excel,包含字段名,文檔為真正的excel文檔,假如文檔不存在,將自動創建文檔,假如表不存在,將自動創建表基于通用性考慮,僅支持導出標準數據類型--鄒建 2003.10--*/
