PL/Perl questions...

Hi List;

 

I have 2 questions...

 

1) I want to create a perl function which connects to an external non-Postgres database and retrieves data. I wonder is the best way to do this to return a set or an array? I assume returning a data set is a better way to go, I want to be able to run something like this:

 

"select a,b,c from my_new_perl_func('odbc-conn', 'sql-string') as t1(a,b,c)";

 

2) can anyone provide me with an example of how to return data from a perl function in this manner based on a DBI query?

 

Thanks in advance for your help...
