Can you show an example of how you'd use those modules to do what mine does? From the documentation I'm looking at, it appears DBD::Sponge is used for making some data appear to be from some SQL, not for doing any kind of transformation.
use DBI;
my $sponge = DBI->connect( 'dbi:Sponge:', '', '', { RaiseError => 1 }
+);
my $sth = $sponge->prepare( 'SELECT name,count(*) FROM ??? GROUP BY na
+me',
{ NAME => [ 'name', 'count' ],
rows => [ [ 'fred ', 10 ],
[ 'john ', 20 ],
[ 'jdporter', 30 ],
[ 'jdporter', 40 ], ] } );
while ( my @row = $sth->fetchrow_array ) {
print join ', ', @row;
print "\n";
}
__END__
fred , 10
john , 20
jdporter, 30
jdporter, 40
