Hi David!
Thanks for the fast reply. So you mean that I might already have created
a connection but am still trying to create the same one again?
>>Check whether the existing one works :)
So how can I test it?
What is the correct way of accessing this data source in a select statement?
Concerning the documents, I wouldn't say that they are unclear about
make_accessor_functions(). The problem is, that in the dbi-link
documents (quote: "Do the following, with the appropriate parameters.
"Appropriate parameters" come from the perldoc of the appropriate
DBD...") and in the dbi-odbc documents I can't find any information
about the correct use of the parameters for the ODBC-connection. That's
why I tried to create the connection so many times.
Regards,
Pit

I have the following problem with PostgreSQL and hope you guys can
help me out in this matter: I try to get a remote connection to any
database (e.g. MS-SQL or MS Access) using DBI-Link and DBD:ODBC. My
problem is, that everything seems fine so far, however I don't know
how to use the parameters for "make_accessor_functions()". I
searched the net for it, but can only find samples for
Perl-Scripting, but I need a sample for using it directly in SQL.
This is what I've come up so far. Hope you can point me to the right
direction.
SELECT make_accessor_functions(
'dbi:ODBC:Northwind::dbi_link.data_source,
'sa'::text,
NULL::text,
'---
AutoCommit: 1
RaiseError: 1
'::dbi_link.yaml,
NULL::dbi_link.yaml,
NULL::text,
NULL, ::text,
'Northwind'::text
);
I have a ODBC connection named "Northwind".
The error message I'm always receiving (for the MS-SQL sample) is:
ERROR: error from Perl function: error from Perl function: duplicate key
violates unique constraint "dbi_connection_data_source_key" at line 94.
at line 35.
SQL state: XX000
It looks like you're trying to connect the same data_source and
user_name twice. Check whether the existing one works :)
Are the documents unclear on the idea that you only run
make_accessor_functions() once per remote (data_source,user_name)
pair per local database?
Cheers,
David.
