I don't think activerecord-jdbc has anything to do with default sizes,
they should be baked into AR's migrations. Is the SQL sent to the
database actually specifying varchar2(4000)?
Yes, the default sizes are in the adapters. The general default for
strings in adapters is to use the largest string length possible. Since
this translates to varchars in most databases it will not cost anything
at all extra to have 4000 instead of 255.

I'm not sure if this is the best place for this question (so redirect if
not) but I was wondering about the String default from the
activerecord-jdbc-adapter.
When using Oracle the default for string seems odd.
create_table :accounts do |t|
t.string :name
end
This will create a column VARCHAR2(4000). I can set the :limit to 255 but I
was curious - why doesn't it do this automatically?
