"select_rows is an abstract method" during "rake db:migrate" February 21, 2008

After successfully building a couple of applications in RoR with SQLite3 and PostgreSQL, I'm now trying to use Oracle as the database for Ruby on Rails application. When I tried db:migrate I ran into an error that said select_rows implementation is not available in oracle_adapter.rb.

After searching for a patch in the RoR Trac, the error is finally resolved. And here the file that fixed the error. Make sure that you installed activerecord-oracle-adapter gem and replace the oracle_adapter.rb with the file attached with this post.

Being an extremely influence by Bruce, I got some conviction that there are only four REAL computer languages in the world other than Perl: C++, Java and [...] Read more – ‘Ruby!’.
