akagrawal3 has asked for the wisdom of the Perl Monks concerning the following question:

Kindly help me with the following 

my $db1      = StatView::Db::D1->connection;
my $db2      = StatView::Db::D2->connection;
....
for my $table ($db1->get_tables) {
 my $resultset   = $table->result_source->source_name;
 my $aggr_table  = $db2->resultset($resultset);

    Statview is not a module on CPAN. It seems to be a private module, so we cannot test it or check its code or documentation. Where did you get it? Cannot you ask the author directly?

    Update: It just might be a subclass of DBIx::Class and then you can have a look at the docs of that module.

      So does that infer that even  result_source->source_name will be available in that document.

        If it is indeed a DBIx::Class private sub-class then you will find it somewhere in the extensive docs of DBIx::Class.

    What does the documentation for "StatView::Db::D1" say?

      I don't have that document. But basically it should contain the database name and other details. I think the first statement connects to a database.

        I don't have that document...

        Gee, well you kinda need to get it, or read the source of the module -- in either case I don't see how we're supposed to help you, we don't have that document either
