thinkerbot / tables_in_string_test.rb

Created July 26, 2010 16:45

tables_in_string patch

	require 'test/unit'

	# These tests illustrate that the tables_in_string will not properly handle
	# oracle table names containing valid non-word characters like '$' or those
	# suffixed with a db link. As a consequence, eager loading can revert to the
	# left-outer-join strategy and ignore select statements on find (see
	# http://gist.github.com/486750).
	#
	# To fix the issue, the regexp in tables_in_string needs to be updated to
	# handle fully-qualified oracle names. As you can see it's kinda ugly to do
