------------------------------------------------

             Summary: Extend simplify for reducing expressions
                 Key: CALCITE-1116
                 URL: https://issues.apache.org/jira/browse/CALCITE-1116
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Jesus Camacho Rodriguez

We would like to cover more cases in expression simplification, such as:

x>5 and x is not null => x>5
x>5 and x is null => not satisfiable
x>5 and x<=5 => not satisfiable
