從sql server中導(dǎo)入/導(dǎo)出 excel 的基本方法

/*===========; 導(dǎo)入/導(dǎo)出 excel 的基本方法 ===========*/

從excel文檔中,導(dǎo)入數(shù)據(jù)到sql數(shù)據(jù)庫中,很簡(jiǎn)單,直接用下面的語句:

/*=============================================*/--假如接受數(shù)據(jù)導(dǎo)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(dǎo)入數(shù)據(jù)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(shù)據(jù)庫中,導(dǎo)出數(shù)據(jù)到excel,假如excel文檔已存在,而且已按照要接收的數(shù)據(jù)創(chuàng)建好表頭,就能夠簡(jiǎn)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(dǎo)成類excel的文檔,注意大小寫:--導(dǎo)出表的情況exec master..xp_cmdshell bcp 數(shù)據(jù)庫名.dbo.表名 out 'c:test.xls' /c -/s'服務(wù)器名' /u'用戶名' -p'密碼'

--導(dǎo)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(wù)器名' /u'用戶名' -p'密碼'

/*--說明:c:test.xls; 為導(dǎo)入/導(dǎo)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(dǎo)出的是類excel文檔,其實(shí)質(zhì)為文本文檔,

--要導(dǎo)出真正的excel文檔.就用下面的方法
