ActiveRecord::Base error with Oracle

Rails
1

I am a noob; got handed this project with no knowledge of Ruby/RoR or
access to the original person who created it.

Anyway, my ActiveRecord::Base implementation is inserting backticks into
the query string sent to Oracle giving me an invalid character error. I
am not sure what to do to remove them.

Code:
class QCTestCycle < ActiveRecord::Base
set_primary_key “TC_TESTCYCL_ID”
end

QCTestCycle.establish_connection(@qc_db[@environment_name])
QCTestCycle.set_table_name “#{@application.qc_table_name}.TESTCYCL”

unique_tests = QCTestCycle.select(“tc_testcycl_id”).where(:tc_cycle_id
=> @application.qc_cycle_id).group(“tc_testcycl_id”).all

Error:

#<ActiveRecord::StatementInvalid: OCIError: ORA-00911: invalid
character: SELECT tc_testcycl_id FROM ONLINE_OLS3_DB.TESTCYCL WHERE
ONLINE_OLS3_DB.TESTCYCL.tc_cycle_id = 463 GROUP BY tc_testcycl_id>

Any help on removing the backticks would be greatly appreciated.
