t-sql导出EXCEL语句--待测试
/*=================== 导入/导出 Excel 的基本方法 ===================*/
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:
/*========================================================*/
EXEC master..xp_cmdshell 'bcp " exec weberp.dbo.DailyCash_Excel @PayAccount=null,@StartDate=null,@EndDate=null,@TrackStation=null" queryout "C:\authors.xls" -c -S "(local)" -U "sa" -P "password"'
--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.
--*/
/*--数据导出EXCEL
导出表中的数据到Excel,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

ExportToExcel @tbname='test',@path='c:\',@fname='test.xls'
