Обсуждение: Writing Text Files from PostgreSQL
Hello. I am brand new to PostgreSQL and I need someone to point me in the right direction on how to write the results of a function to a text file. Is it possible to do this within the PostgreSQL PL/pgSQL language? I have done this before in Oracle using the UTL_FILE commands and I was hoping that PostgreSQL had similar functionality. I need to provide some data formatting in the text file that I produce so I don't think the pg_dump command would work for me (correct me if I am wrong though). Thanks in advance for any help that you can give.

Is it possible to do this within the PostgreSQL PL/pgSQL No, this is a trusted language. But you can use untrusted languages such as plperlu or plsh. 21:05 < akretschmer> ??plperl 21:05 < rtfm_please> For information about plperl 21:05 < rtfm_please> see http://pgfoundry.org/projects/plperlng/ 21:05 < rtfm_please> or http://www.postgresql.org/docs/current/static/plperl.html HTH, Andreas -- Really, I'm not out to destroy Microsoft.
