Обсуждение: How to view the code of a function
Hi,
I’m trying to look at the source code of a function in PostgreSQL. Could anybody please let me know how to view the same?
Thanks,
Venkat

Can anyone recommend a good, easy to ease and inexpensive reporting tool for accessing and manipulating Postgre database/table? The key features I am looking for with this tool are as follows:
- Require less programming effort. I am trying to stay away from having to write sophisticate programming language, such as Java or .Net
- Allow to bundle SQL commands in store procedure like style.
- Allow to evaluate conditions of SQL result set and trigger alert email based on preset threshold.
Thanks.
Alan

Have you seen this: http://www.zwartberg.com/surf.html You can write SQLs or calls to PLPGSQL (stored procedure) directly into the XML configuration file, then generate a web front end. No Java or C++ required, though you can make complex features in C++. But for more complex GUI logic, you'll need Javascript. There is no escaping writing programs to describe logic, but the straight-forward front-end is all auto-generated from your XML configuration and HTML. To do email from triggers will require extra coding, but talk to me about it... The Karoo Project is new, and the documentation is a bit lacking, but you can email me your questions "Brian Modra" <brian@zwartberg.com> > > > Thanks. > > Alan > > This email and all files and information transmitted with it are > confidential and intended solely for the use of the individual or entity to > whom the email is addressed.

Brian, What you mentioned below is more sophisticated than what I am capable of doing now. Could you or anyone on this email recommendother tool that meets the following requirements: 1. Require less programming effort. I am trying to stay away from having to write sophisticate programming language, such as Java or .Net 2. Allow to bundle SQL commands in store procedure like style. 3. Allow to evaluate conditions of SQL result set and trigger alert email based on a preset threshold. -----Original Message----- From: Brian Modra [mailto:epailty@googlemail.com] Sent: Friday, December 11, 2009 3:09 PM To: Su, Alan Cc: pgsql-admin@postgresql.org Subject: Re: [ADMIN] Looking for Good and Easy-to-use Reporting Tool 2009/12/11 Su, Alan <Alan.Su@daiwausa.com>: > Can anyone recommend a good, easy to ease and inexpensive reporting tool for > accessing and manipulating Postgre database/table?

Have you considered psql and grep, with maybe a little logic in bash? -Kevin

Do you need any sort of GUI front end to the application?
