以CSV格式导出数据表sql server 2008

Question

我需要创建一个存储过程来查询表并为指定目录位置中的数据创建一个CSV文件。

我该怎么做？

Answer 1

您无法直接使用存储过程。我建议在SQL Server Management Studio中右键单击数据库，然后选择“导出数据”。

为它提供一个查询或返回行的存储过程。告诉它你希望文件由逗号和用引号限定的文本分隔。

当向导询问您是要执行还是保存时，请将其保存到磁盘。

这使得所谓的SSIS包。然后，您可以使用Windows资源管理器来运行它，或者使用名为dtexec.exe的命令行程序来运行它，或者将它提供给DBA，让它们在SQL Server中运行它。

Answer 2

您可以通过exec调用BCP的xp_cmdshell 'BCP dbname..table出filename.bcp .....'

这是一个非常类似的问题，除了它的进口。 Use bcp to import csv file to sql 2005 or 2008

See here for more information on BCP.

Answer 3

这是可能做到，但你需要有足够的权利来运行xp_cmdshell和即席分布式查询。
