in thread Dancer + SQL::Translator

I saw that error creep up many times when i was trying to put this together. Looks like more will be necessary than simply replacing the name of the database vendor/driver. Take a look at the value for $sql and see what part(s) are invalid for Oracle. As for GraphViz2, normally i would jump up to upgrade but in this case i just need something quick and dirty to help me visualize my problem that needs to be solved. Thanks for your time. :)

It is the double bracketed values in the timestamp definition.

CREATE TABLE "ACCOUNT" (
  "ACCOUNT_ID" number(38) NOT NULL,
  "DATE_TIME_UTC" timestamp(6)(11),
  "CURRENCY_ID" number(38) NOT NULL,
  "NAME" varchar2(128) NOT NULL,
  "BALANCE" number(14) NOT NULL,
  "ACCOUNT_TYPE_ID" number(38) NOT NULL,
  "CREATED_BY_USER" varchar2(128),
  "CREATED_DATE_TIME_UTC" timestamp(6)(11),
  "MODIFIED_BY_USER" varchar2(128),
  "MODIFIED_DATE_TIME_UTC" timestamp(6)(11)
);

When the table was originally created those columns were only timestamps with no precision.

I spoke to one of the maintainers of SQL::Translator and after a suggestion from him I arrived at the following which avoids the problem above:

my $translator = SQL::Translator->new(
    from        => 'DBI',
    to          => 'GraphViz',
    parser_args => {
        dsn         => "dbi:Oracle:xxx",
        db_user     => 'xxx',
        db_password => 'xxx',
        producer_args => {
            output_type   => 'png',
            out_file => 'out.png',
            natural_join  => 1,
            width => 30.0,
            height => 30.0,
            #fontsize => 10
        },
    },
   );
my $sql = $translator->translate( data => '');

unfortunately our schema is quite large and the above produces a png which although looks like it might be correct is unreadable - everything is too small. The png output is limited in size apparently. I tried generating a postscript file as well but I don't seem to be able to produce one of those - nothing is output. Maybe I don't have whatever GraphViz needs to generate postscript.
