Handle sub query

[jbarotin]

Hi,

It's a nice initiative, I haven't found an other project that aim to do a such feature.

I try this kind of query :
select a.foo as f1, b.bar as b1 from table_a a LEFT JOIN ( select id,bar FROM test) b on a.id = b.a_id where a.quuz = 2

And it gives me the following message
Bad table or column name: '(select' has chars not alphanumeric or underscore! at /usr/local/share/perl5/GraphViz/SQL.pm line 41. $VAR1 = 'sql'; $VAR2 = 0; Can't use an undefined value as a HASH reference at /usr/local/share/perl5/GraphViz/SQL.pm line 112.
