Description
The following test in RelOptRulesTest causes a crash:
@Test void testArrayRepeat() { final String sql = "select array_repeat(1, null)"; sql(sql) .withFactory( t -> t.withOperatorTable( opTab -> SqlLibraryOperatorTableFactory.INSTANCE.getOperatorTable( SqlLibrary.STANDARD, SqlLibrary.SPARK))) .withRule(CoreRules.PROJECT_REDUCE_EXPRESSIONS) .check(); }
The crash is:
java.lang.AssertionError: Cannot add expression of different type to set: set type is RecordType(INTEGER NOT NULL ARRAY NOT NULL EXPR$0) NOT NULL expression type is RecordType(INTEGER NOT NULL ARRAY EXPR$0) NOT NULL set is rel#4:LogicalProject.(input=HepRelVertex#3,exprs=[ARRAY_REPEAT(1, null:DECIMAL(19, 9))]) expression is LogicalProject(EXPR$0=[null:INTEGER NOT NULL ARRAY]) LogicalValues(tuples=[[{ 0 }]]) Type mismatch: rowtype of original rel: RecordType(INTEGER NOT NULL ARRAY NOT NULL EXPR$0) NOT NULL rowtype of new rel: RecordType(INTEGER NOT NULL ARRAY EXPR$0) NOT NULL Difference: EXPR$0: INTEGER NOT NULL ARRAY NOT NULL -> INTEGER NOT NULL ARRAY at org.apache.calcite.plan.RelOptUtil.verifyTypeEquivalence(RelOptUtil.java:419) at org.apache.calcite.plan.hep.HepRuleCall.transformTo(HepRuleCall.java:60) at org.apache.calcite.plan.RelOptRuleCall.transformTo(RelOptRuleCall.java:273) at org.apache.calcite.plan.RelOptRuleCall.transformTo(RelOptRuleCall.java:288) at org.apache.calcite.rel.rules.ReduceExpressionsRule$ProjectReduceExpressionsRule.onMatch(ReduceExpressionsRule.java:317) at org.apache.calcite.plan.AbstractRelOptPlanner.fireRule(AbstractRelOptPlanner.java:337)
