Reading external files from in T-SQL

[Wallstyouth]

I'm Trying to create a stored procedure that reads the contents of a file and executs some operations on this file anyone have sample code they could provide?

Thanks.

I found this link. Maybe you can accomplish the file I/O part but I'm not sure about using t-SQL for file operations.

Really cool. I may find some use of this in the future.
Are you able to point to a file on a network drive?
