Question

我需要创建一个存储过程来查询表，并在指定的目录位置为该数据创建一个CSV文件。

我该怎么办？

Answer 1

您无法直接使用存储过程执行此操作。我建议在SQL Server Management Studio中右键单击您的数据库，然后选择“导出数据”。

使用返回行的查询或存储过程提供它。告诉它你希望文件用逗号分隔，文本用引号限定。

当向导询问您是要执行还是保存时，请将其保存到磁盘。

这会产生一种称为SSIS包的东西。然后，您可以使用Windows资源管理器运行它，或使用名为dtexec.exe的命令行程序来运行参数，或者将其提供给DBA以让它们在SQL Server中运行。

Answer 2

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

除了导入之外，这是一个非常相似的问题。 Use bcp to import csv file to sql 2005 or 2008

See here for more information on BCP.

可以这样做但你需要有足够的权限来运行xp_cmdshell和ad hoc分布式查询。
