             Summary: Extend simplification of expressions with CEIL function over date types
                 Key: CALCITE-2334
                 URL: https://issues.apache.org/jira/browse/CALCITE-2334
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.17.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Julian Hyde


CALCITE-2332 disables simplification of CEIL function due to correctness issues.

{{FLOOR}} and {{CEIL}} cannot be handled with the same logic. For instance, {{CEIL(CEIL(x TO HOUR) TO YEAR)}} cannot be simplified, e.g., '2011-12-31 23:59:59', while {{FLOOR(FLOOR(x TO HOUR) TO YEAR)}} can be simplified. Hence, we need new logic to enable simplification of CEIL function on date types.
