[jira] [Created] (OPTIQ-418) Complete interpreter

Julian Hyde created OPTIQ-418:
---------------------------------

             Summary: Complete interpreter
                 Key: OPTIQ-418
                 URL: https://issues.apache.org/jira/browse/OPTIQ-418
             Project: Optiq
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


In OPTIQ-416, we added the Interpreter class. It is able to handle RelNode types scan (over array-table at least), filter, project, values, sort; and RexNode types literal, inputRef, and calls to < and >.

This task is to complete implementation of the interpreter. This includes implementations of aggregate, join, union, minus, intersect, correlator RelNodes and of the set of built-in operators.

To prove that the interpreter is working, add a test that executes several complex queries over small data sets. (Maybe run the foodmart queries manually?) Also add a sub-class of SqlOperatorTest that interprets rather than generating code.
