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.
