Two minor notes:

First, you might want to be careful about the values returned by $sth->{NAME} if you care about case-sensitivity. The DBI doesn't make them consistent or modify them at all -- they're whatever the database returns. And what the database returns can be vendor specific. The NAME_uc and NAME_lc properties do what you'd expect.

Second, I think the integer values returned from $sth->{TYPE} correspond to the DBI SQL type constants. So you can do:

use DBI qw( :sql_types );
...
my $types = $sth->{TYPE};
foreach my $type ( @{ $types } ) {
  print "VARCHAR"  if ( $type == SQL_VARCHAR );
  print "DATETIME" if ( $type == SQL_DATETIME );
  print "BOOLEAN"  if ( $type == SQL_BIT );
  print "FLOAT"    if ( $type == SQL_FLOAT );
  ...
}

Conveniently, most of them also map to the ODBC CLI specifications. :-)

You can find the type-to-constant mapping in the 'dbi_sql.h' header file found in your architecture-dependent perl library tree -- for example, mine is in site_perl/5.6.1/i686-linux/auto/DBI/dbi_sql.h
