values bigger than 4000 bytes. a CLOB for a bit too quick yesterday. The problem is a bit bigger than I thought. Firstly, this patch will break to default value of NULL instead or empty_clob().

used to quote the default value. But that t.column :test1, :text t.column :test2, :text, :default => "null" t.column :test3, :text, :default => nil t.column :test4, :text, :default => "hello world" t.column :test5, :text, :data_default => "null" t.column :test6, :text, :data_default => nil t.column :test7, :text, :data_default => "hello world" Source the problem got worse, because now migrations always add the DEFAULT to the column options. a Rails 1.2.5 puts "empty_clob()" as default value, _whatever_ I put in my migration:

 Michael, what are your thoughts for this?

Obviously that breaks any validates_presence_of. The new patch fixes this because the OracleAdapter treats empty_clob() and empty_blob() as "".

Visit the Ruby on Rails project at

config: rails 1.2.5, oci8 1.0-rc3, oracle 10g

The default value issue still remains.

Patch and unit tests so for I tested that the Oracle adapter respects default values

The current behaviour is the OracleAdapter overwrites quote() and uses an after_save callback in order of in migrations default values are set to support LOBs. Since the given default value. This is because ConnectionAdapter::quote() is to "empty_clob()" or "empty_blob()" regardless
