Hi,
I have a question regarding how DB connections work within a single process perl script. Hope someone doesn't mind giving me a few pointers.

If I was to have a sub routine that setups a connection and returns a connection handler variable (or perhaps a reference), such as the code shown below. If I then call this sub everytime I need to make a query (my $dbh = &dbConnect), am I right in thinking that a new connection would NOT be openend every time but that DBI would use an existing connection if one existed and was not already in use; assuming that I hadn't yet called disconnect()

My second question is: Is the connection opened on the call to connect or is it delayed until the first query is prepared?

Regards to all,
Cyril


sub one {

  my $dbh = &dbConnect;
  # query continues here

}

sub two {
  
  my $dbh = &dbConnect;
  # query continues here
}
sub dbConnect {

        my $dsn = "DBI:mysql:database:localhost";
        my $db_user_name = 'username';
        my $db_password = 'password';
        my $dbh;
        $dbh = DBI->connect
                ($dsn, $db_user_name, $db_password,
                {
                        RaiseError => 1 

                }
                        ) or die("cannot connect to DB: ".DBI::errstr.
+"\n",$dbh);

       
        return $dbh;
