AssertionError during optimization of EXTRACT expression

    XMLWordPrintableJSON

Details

    Description

      The following test added to RelOptRules test causes an AssertionError:

        @Test void testExtractDayFromTime() {
    final String sql = "select EXTRACT(DAY FROM TIME'10:00:00')";
    sql(sql).withRule(CoreRules.PROJECT_REDUCE_EXPRESSIONS)
        .check();
  }

      The bottom of the stack trace is:

      java.lang.AssertionError: unexpected TIME
	at org.apache.calcite.adapter.enumerable.RexImpTable$ExtractImplementor.implementSafe(RexImpTable.java:3056)
	at org.apache.calcite.adapter.enumerable.RexImpTable$AbstractRexCallImplementor.genValueStatement(RexImpTable.java:3796)
	at org.apache.calcite.adapter.enumerable.RexImpTable$AbstractRexCallImplementor.implement(RexImpTable.java:3758)

	at org.apache.calcite.adapter.enumerable.RexToLixTranslator.visitCall(RexToLixTranslator.java:101)
	at org.apache.calcite.rex.RexCall.accept(RexCall.java:189)

      This expression is indeed illegal. Perhaps validation should produce an error?
