I have the problem, that I can't find out, how I can access a PostgeSQL database.
I've tried to use odbc but I failed. (odbc:connect())
So I looked for a solution by other people and found a doc from ejabberd. I need to intsall jungler but this project is dead?
Well, can you tell me what I have to do?
Thx  |

The OTP ODBC application is not among their best and efficent ones released by Ericsson. That is why many bypass it and write their own drivers or APIs. It does work, however, so the issues on your end must be with configuration. I would check the documentation and not be scared of reading the code to find out what is going wrong.
Jungerl is a repository for erlang developers to contribute their own code. It is alive, contains lots of interesting modules and used by many.
Hilsen,

Well, I know odbc shouldn't be prefered but in this case I need also a way to connect to arbitrary databases such as mysql.
I wondered why I wasn't able to connect by using odbc:connect().
My problem was a wrong connection string and I coudn't find out which arguments I needed to pass.

| When I come across similar errors and the reply is cryptic, the quickest way is to use dbg (see the manual page) and work my way down through the module until I find what is going wrong. Last time I did that was a few years ago. In about an hour, I figured out we had configured the snmp agent to handle v3 vs our system and mibs only managing snmp v1. Others had spent days on it, and only finding where in the code the request was failing helped. |
