Oracle and Rails seems really slow.... In development
...w
select column_name, data_type, data_default, nullable,

''VARCHAR2'', data_length,

decode(data_type, ''NUMBER'', data_scale, null) as scale

and syn.synonym_name (+)= cat.table_name
and col.table_name = nvl(syn.table_name, cat.table_name)

OCI adapter slowdown on dictionary access
Hi,
after some experience with Rails on MySQL databases I gave it a try on one
of our larger Oracle database.
I was facing a problem when Rails tried to detect the columns for a
model/table. The appropriate statement ran about 1 min which led to a

ActiveRecord: Oracle metadata loading slow on large database
...select column_name, data_type, data_default, nullable,

and syn.synonym_name (+)= cat.table_name
and col.table_name = nvl(syn.table_name, cat.table_name)
and col.owner = nvl(syn.table_owner, user)
At first glance, the query looks okay. Oracle should apply the WHERE
clause on the FROM...

Legacy Table works-except edit?
Greetings,
I''m trying to put a Rails face on a Legacy Oracle 10 table. I am
currently setting the table_name and primary_key, and I get the list
and show to work fine.
However, when I hit edit I just get the Editing <table name>, Edit
button, Show, and Back. None of the fields are rendered.
Why would I be able to show these fields in the show and list, but not
edit them in the
