Join bug with explicit column refs #181

Closed neilconway closed 13 years ago

neilconway commented 13 years ago

Test case:

require "rubygems"
require "bud"

class TestJoinExplicitPreds
  include Bud

  state do
    table :t1
    table :t2
    table :t3
  end

  bootstrap do
    t1 << [1,2]
    t2 << [3,4]
  end

  bloom do
    t3 <= (t1 * t2).pairs(t2.key => t2.val)
  end
end

TestJoinExplicitPreds.new.tick

Result:
