* Add Nodes::TableAlias#engineJon Leighton2012-07-131-0/+4
| | | | | Eventually #engine should go away, but until that time, this means that Table and Nodes::TableAlias can be used more interchangeably.
* Remove ArgumentError.Jon Leighton2012-07-131-2/+1
| | | | | | | | | | It is untested. There is no `@frame` variable. Presumably it is supposed to be `@framing`, but changing that shows that some of the tests *are* setting frame twice. I don't see why this level of strictness is necessary. If someone disagrees, they should add a test for this behaviour and make the other tests pass.
* Include Predications in GroupingErnie Miller2012-05-193-7/+7
| | | | | | Also, removed unused ordering.rb file, since it is identical to the one being created in unary.rb already, and isn't required anywhere.
* Must support aliases for OVER operator.Alexander Staubo2012-02-231-0/+2

* Add nodes for boolean constantsDaniel Cadenas2011-08-032-0/+34
| | | | | | | | | | | | This is useful for dynamically created predicates e.g: expr1 = table.create_false expr2 = table.create_false expr1 = create_a_predicate() if some_condition expr2 = create_another_predicate() if some_other_condition table.where(expr1.and(expr2))
