问题
I'm new to Rails and I'm not sure why my chaining isn't working.
Working
my_model.select('name').where('status_id = 6').all
Not Working
my_model.select('name').where('status_id = 6').order('name')
Why does chaining the order after the where not execute the query? I've tried adding the .all after the .order but that didn't seem to work either.

Looks like this is a known bug in the jdbc adapter: http://kenai.com/jira/browse/ACTIVERECORD_JDBC-154
If you make these changes it will fix it: https://github.com/ystael/activerecord-jdbc-adapter/commit/8815d2fe133afb6774ebe12cc27c3a977dbf7ad2
