      Native evaluation does not respect ordering. MDX sets, unlike SQL sets, are deterministically ordered. So for instance

      {X, Y}


      {A, B}

      must return

      {(X, A), (X, B), (Y, A), (Y, B)}


      Pushing the evaluation down to SQL is very desirable for performance reasons. However, the SQL results may come back in a different order. If the SQL is generated without an ORDER BY clause the results may be different for different databases.

      One example of this failure is mondrian.test.clearview.SummaryTest.testRankExpandNonNative. It occurs on MySQL with mondrian.native.crossjoin.enable=true.
