RE: VB and ODBC

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

When using Access, because it is essentially a file-based db, rather
than server-based, you give the filename.  With Postgres, you will
probably not have to give the data source a name, but you will have
to change the parameters in the connection string.  I think that the
Name parameter is used to give the connection a name internal to the
script that you're running.  It's only a temporary thing.  The
connection string should probably be something like:

constr = "ODBC;DSN=Your_DSN;UID=user;PWD=password"

Your_DSN needs to be a DSN that you have already defined in the
control panel, user needs to be the database user, and password for
the password, if it's required.  You may also get away with this:

constr =
"ODBC;Driver={PostgreSQL};SERVER=Your_Server;DATABASE=Your_Database;UI
D=user;PWD=password"

which means that you don't have to create the DSN beforehand.  The
DATABASE keyword may not be right, but I can't remember what it is
offhand for Postgres.  Each vendor has it's own set of keywords,
although UID and PWD seem to be pretty universal, and the ODBC prefix
is always required for ODBC connections (remember, DAO doesn't assume
that you want to use ODBC, you have to tell it).  If you feel like
tracing the connection (using the first method), then you can find
out what the keywords are ;-) and use the second.

Cheers...
