Re: Can PostGreSQL handle 100 user database - more info - Mailing list pgsql-general

I am not sure what an ole db provider is? This must be another method of
talking to the server from a client application. What advantages does it have?

I have the open source ODBC client (and I know a Java version exists), it seems
ok but I don't know if it handles things like transactions and other advanced
functions.

It would obviously be important to have a good method of talking to P-sql from
Windows since a lot of people will want to do this.

I have only just started looking at this but if I find any limitations I'm sure
I will post them!!!

One thing to consider since you mentioned VB is the lack of ole db provider.
It really puts a black mark on the DB for Windows developers.

Unfortunately only one person has volunteered to try to make one, but he is
extremely busy (as most of us are).

Part of the drawback of making one is software and knowledge needed.  You
need a good understanding of the way the database talks to the client, the
database schema and other topics.  As for the software, it seems atleast
VC++ 6.0 is best.

ODBC can be used, but again, there is faltering support for it also.

I'm not pointing fingers, just things to look out for since you are a VB
programmer.  I'd be more than willing to give the provider a try (while
asking many questions along the way), but the problem of not having VC++ is
a major obstacle.
