從excel文件中,導入數據到sql數據庫中,很簡單,直接用下面的語句:
/*===================================================================*/
--如果接受數據導入的表已經存在
insert into 表 select * from
openrowset('microsoft.jet.oledb.4.0'
,'excel 5.0;hdr=yes;database=c:/test.xls',sheet1$)
--如果導入數據并生成表
select * into 表 from
openrowset('microsoft.jet.oledb.4.0'
,'excel 5.0;hdr=yes;database=c:/test.xls',sheet1$)
/*===================================================================*/
--如果從sql數據庫中,導出數據到excel,如果excel文件已經存在,而且已經按照要接收的數據創建好表頭,就可以簡單的用:
insert into openrowset('microsoft.jet.oledb.4.0'
,'excel 5.0;hdr=yes;database=c:/test.xls',sheet1$)
select * from 表
--如果excel文件不存在,也可以用bcp來導成類excel的文件,注意大小寫:
--導出表的情況
exec master..xp_cmdshell 'bcp 數據庫名.dbo.表名 out "c:/test.xls" /c -/s"服務器名" /u"用戶名" -p"密碼"'
--導出查詢的情況
exec master..xp_cmdshell 'bcp "select au_fname, au_lname from pubs..authors order by au_lname" queryout "c:/test.xls" /c -/s"服務器名" /u"用戶名" -p"密碼"'
說明.
c:/test.xls 為導入/導出的excel文件名.
sheet1$ 為excel文件的工作表名,一般要加上$才能正常使用.
下面是導出真正excel文件的方法:
/*--數據導出excel
導出表中的數據到excel,包含字段名,文件為真正的excel文件
,如果文件不存在,將自動創建文件
,如果表不存在,將自動創建表
基于通用性考慮,僅支持導出標準數據類型
