Making DBI’s type info data usable for its quote method

I’m putting this here mostly as future copy-paste fodder:

my %sql_type = do {
    my $ti = $dbh->type_info_all;
    my $tidx = shift @$ti;
    my ( $n, $t ) = @$tidx{qw( TYPE_NAME SQL_DATATYPE )};
    map {; uc $_->[$n], $_->[$t] } @$ti;
};

Now you can say things like $dbh->quote( $latitude, $sql_type{'DOUBLE'} ). This is useful in situations where you cannot use placeholders, e.g. when generating some kind of fixture.sql file from CSV data.
