Re: BEST odbc driver for windows MS Access

I installed pgsql yesterday on my windows xp. I was under the impression
that I needed to also download and install a specific odbc driver so that MS
Access could link to pgsql tables. Someone explained to me that an ODBC
automatically installs now, when I install pgsql. Sure enough, they were
right. I was able to find an ODBC driver and link MS Access to pgsql.

My question is this: Is that default odbc driver, which installs with pgsql
the best one to use for MS Access? I notice that there are a confusing
array of odbc drivers to download. What is the difference between all of
them. How can one decide which is best for a particular purpose, such as MS
Access.

Do many of you use MS Access as a front end to pgsql?

Thanks!

I am not yet using Access as a front end to pgsql, but it is something I
would like to get set up in the future, and I AM in the very early
stages of developing an application which has an Excel front end to
pgsql, and the data connection issues here may be very similar. I am
currently comparing the use of ODBC vs. OLEDB (with ADO in VBA) to
connect to pgsql and pull data in. I think OLEDB will be faster and
more stable...IF a good OLEDB driver for pgsql exists, that is. And if
not, will I have to go thru MSQuery to get to pgsql via ODBC? I hope not...

So I don't have an answer for Karabac, but I'll looking at the same
questions and I'll post what I find. And if anyone has thoughts or
experience on OLEDB vs. ODBC for connecting to pgsql from Microsoft
software, I'd love to hear of them!

I posted my question at utteraccess.com and was directed to this link as the
best odbc driver for postgres

http://pgfoundry.org/projects/psqlodbc/

I am wondering how it differs (or if it differs) from the odbc which was
installed automatically when I installed pgsql.

That link leads to this link for Window

http://pgfoundry.org/softwaremap/trove_list.php?form_cat=216

The page at the first mentioned link ALSO least to this page

http://www.postgresql.org/ftp/odbc/versions/

and it is at THIS LINK that I find great confusion as to WHICH ODBC driver I
should be downloading for my DELL Windows XP

since it says

PARENT DIRECTORY

DLL

MM

MSI

OLD

SRC

And the DLL link shows a myriad of zipped choices for download, at the top
of the list being

psqlodbc-07_01_0007.zip
<http://wwwmaster.postgresql.org/download/mirrors-ftp?file=odbc%2Fversions%2
Fdll%2Fpsqlodbc-07_01_0007.zip>

SO, if anyone has any guidance in this matter, I would be most grateful

Thanks!

Each of the above directories are giving you the option has to how you would like to have your
ODBC driver installed.

DLL -- probably give you only the dll files. You will have to manual install them and register in
the windows resistry your self. MM -- not to sure what it is for. MSI -- give you the odbc
drivers in a format that will install themselves after you execute the msi file. OLD -- probably
old drivers kept for anyone that specifically needs the old drivers. SRC -- give you the sources
code from the odbc driver. This way you can compile it yourself and then install it into windows
yourself.

I expect you should just choose the MSI directory since it is the easiest method to install your
odbc drivers.

Pick the newest driver. it will be the driver with the largerst number.

I am not to sure how to answer your question. The functionality does MSQquery give you that you
get some other way with OLEDB.

My opionion of OLEDB for postgresql is that it is broken and certainly not more stable in this
case. Even worse, there doesn't seem to be much support for the oledb project as compared with
the odbc projects. If you find that a bug keeps you from completing your project, there aren't
very many places to turn.

from the following link:

http://archives.postgresql.org/pgsql-odbc/2006-10/msg00009.php

you see that an old version of ODBC was able to handle a load of 600 transactions requests per
second. The Command Prompt odbc-ng appears to almost double this throughput, however it breaks
when I try to use it. This should be expected since this driver is still released as being under
the "public test mode".

If you are enterested in using the odbc-ng driver you could use the following mailing list for
help:

http://lists.commandprompt.com/mailman/listinfo/odbcng

This is what I'm not actually sure of, but some more research I've done
tonight seems to indicate that the method I've used accessing an OLEDB
source entirely from within code (which is what I'm trying to do) may be
completely adaptable to an ODBC source.

Using SQL Server as an example, I can connect from Excel VBA using code
that looks something like this:
oConn.Open "Provider=sqloledb;Data Source=Aron1;Initial
Catalog=pubs;User Id=sa;Password=asdasd;"00)

I was hoping I could replace the "sqloledb" provider with the proper
reference for the postgresql oledb provider and have a working connection!

I now find that I can theoretically also connect to SQLServer thru ODBC
using a connection string in VBa that looks something like:
oConn.Open "Driver={SQL
Server};Server=Aron1;Database=pubs;Uid=sa;Pwd=asdasd;"

So again, if I install the PostgreSQL ODBC driver and put it in there in
place of {SQL Server}, I should have a working connection I can pass SQL
thru from code...right? :-) That's what I'm going for anyway. I am
really just looking to do pretty simple querying and writing back to the
database with this. If ANYONE out there has any experience with this,
from any MS application using VBA, I would appreciate hearing from
them...and any references to other message lists are welcome too -
thanks for the pointer to the odbcng list, Richard.

If you install the MSI version of the driver, it will also install odbc help documentation in your
windows start menu. There is an example of how to connect using vb. Also if you search the odbc
mailing list archieves you will find many other examples that show how to do this. There are some
important "lessons learned" about linking tables via ms-acces also documented in the archieves.

to search odbc list archieves check out the following link:
http://archives.postgresql.org/pgsql-odbc/

one of the many sample ado connection scripts:
http://archives.postgresql.org/pgsql-odbc/2006-11/msg00019.php

Here is one such bit of advice:

Thanks for the compliment with you refered to me as an "expert". :-)
http://www.utteraccess.com/forums/showflat.php?Board=36&Number=1312899

But I am really just a novice on the list just like you are. Only I've had a little more time to
get familar with PG web site than you have.

If you want to see a list of the REAL experts check out:
http://www.postgresql.org/developer/bios

Do a "find" for "odbc" on that webpage and you will see the people that actually deserve that
compliment.

You bring up valid points regarding the postgresql website about where it can be improved.
However, your suggestions can only be inacted if you report them to the correct people.

So regarding you consern about what MSI,DLL,MM,SRC, et.al acutally mean:
http://www.postgresql.org/ftp/odbc/versions/

and why the odbc driver are sorted in ascending vs descending order:
http://www.postgresql.org/ftp/odbc/versions/msi/

since your concerns address the display of the postgresql website, you should post your concerns
to:
webmaster(at)postgresql(dot)org

If this is the wrong person, they will know who to forward your conserns on to. At least this way
your concerns can be addressed by people who have the ablity to make changes.

When you post problems such as these on non-postgresql mailinglists you are not doing yourself or
anyone else a favor.

It's the same code (might be a different version though). The pgFoundry
site is where the development work happens.

Yes, it says:

psqlODBC is the official PostgreSQL ODBC Driver. Downloads are available
on the PostgreSQL Mirror network at http://www.postgresql.org/ftp/odbc/

I'm sure you can guess what that one is :-)

Thats the driver distributed as a zip of the dll's - not recommended
unless you know what you're doing.

That's the driver distributed in a Windows Installer Merge Module, for
developers to include in their own installers.

That's probably what you want - the standard Windows Installer MSI package.

Old (well, archaic versions)

Source code.

Yes - unless you specifically need an older version for some reason, get
the latest. No-one is likely to support the older ones, and the first
question you're likely to be asked is 'are you running the latest version'?

I'll add a readme to that directory on the FTP site though... thought
there was one already :-(

Very helpful, thanks!
