使用UTF-8的xp_cmdshell写入文件 [英] Write to file with xp_cmdshell in UTF-8

问题描述

  SELECT @command ='echo'+ @fileContent +'> e：\ out\'+ @fileName +'.csv'
 exec master.dbo.xp_cmdshell'mkdire：\ out\''
 exec master..xp_cmdshell @command 
  

问题是文件内容不是UTF-8，所以有些特殊字符是错误的。 / p>

我可以使用UTF-8编码创建文件吗？ 您可以使用 SQLCMD 代替旧的tecnique作为DOS outupt redirect

  sqlcmd -S ServerName -d DataBaseName -E -oCSV文件路径和位置 - Q您的查询-W -w 4000 -s; -f 65001 
  

交换机 -f 65001 指示使用UTF8作为outfile文件

  SELECT @command ='sqlcmd -S ServerName -d DataBaseName -E -o'+ @fileName +' - Q您的查询-W -w 4000 -s; -f 65001'
 exec master.dbo.xp_cmdshell'mkdire：\ out\'
 exec master..xp_cmdshell @command 
  

ps我无法测试，所以请检查SQLCMD文档

希望它有帮助

I am creating files with xp_cmdshell like this:

SELECT @command = 'echo ' + @fileContent + ' > e:\out\' + @fileName + '.csv'
exec master.dbo.xp_cmdshell 'mkdir "e:\out\"'
exec master..xp_cmdshell @command 

The problem is that the file contents is not in UTF-8 and so some special characters are wrong.

Can i create the file in UTF-8 encoding?

解决方案

You can use the SQLCMD instead the old tecnique as DOS outupt redirect

sqlcmd -S ServerName -d DataBaseName -E -o "CSV File Path & Location" -Q "Your Query" -W -w 4000 -s ";" -f 65001

the switch -f 65001 indicate to use UTF8 as outfile file

SELECT @command = 'sqlcmd -S ServerName -d DataBaseName -E -o "'+ @fileName +'" -Q "Your  Query" -W -w 4000 -s ";" -f 65001'
exec master.dbo.xp_cmdshell 'mkdir "e:\out\"'
exec master..xp_cmdshell @command

p.s. i cant test it so please check the SQLCMD documentation

Hope it help
