Обсуждение: fetching text file from internet
Hi to all. I need download text file from internet, and I'll use plpgsql, but I don't know if this language can do this. Ideas? Where I can find documentation more precisely than postgresql manual? Thank you, hi Billo Dario rodario@libero.it

I think you need something like plperl, plpython, or pltcl that knows how to make network connections. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073

Is there a reason you want to do this in server code instead of in the client? If you must implement download functionality on the server side, then you could write a function in C or one of the other PLs (PL/Perl, PL/Tcl, PL/Python, etc.) and call it from PL/pgSQL. -- Michael Fuhr http://www.fuhr.org/~mfuhr/
I'd be surprised to find out that plpgsql could do this natively - it's not a database function you're trying to perform. Try using wget or curl to obtain the file in a shell script, then run your plpgsql to slurp in the **local** file.

In pl/perlu (and likely python, maybe others), you can easily download a file from the internet, parse it, and return results. If it is a type of file parseable by DBD::AnyData, then you could use dbi-link to make this file available as a table in your database.
