导入/导出Excel_sqlserver

sqlserver 搞代码 3年前 (2018-06-16) 74次浏览 已收录 0个评论

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:

/*===================================================================*/
–如果接受数据导入的表已经存在
insert into 表 select * from

http://www.gaodaima.com/35459.html导入/导出Excel_sqlserver

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.

 

下面是导出真正Excel文件的方法:

/*–数据导出EXCEL
 
 导出表中的数据到Excel,包含字段名,文件为真正的Excel文件
 ,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
 基于通用性考虑,仅支持导出标准数据类型

/*–调用示例

drop procedure [dbo].[p_exporttb]
