Unfortunately formatting is broken but first of internal selects cannot be
generated in 1.35.0 version.
> Assertion error in aggregate

> Key: CALCITE-5888
> URL: https://issues.apache.org/jira/browse/CALCITE-5888
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.35.0
> Reporter: Petr Masopust
> Priority: Major
>
> We have {{relBuilder.aggregate(groupKey, aggregateCalls)}} in our code with
> values {{[AS($31, 'a_label_d_opp_stage_id_foodmart_bd4c9c91212f9f'),
> AS(CAST(FLOOR($34, FLAG(QUARTER))):TIMESTAMP(0),
> 'a_label_snapshot_timestamp_quarter_foodmart_89fe710c8628d9')]}} and
> {{[COUNT(CASE(AND(COALESCE($37, false), =($36, $13)), $15, null:NULL)),
> SUM(CASE(AND(COALESCE($37, false), =($36, $13)), $2, null:NULL)),
> MAX(CASE(AND(COALESCE($37, false), =($36, $13)), 0, null:NULL)),
> MAX(CASE(AND(COALESCE($37, false), =($36, $13)), 0, null:NULL))].}}
> It works perfectly in version 1.34.0 but in 1.35.0 we got this exception:
> {{java.lang.AssertionError}}
> {{ at org.apache.calcite.rel.core.Aggregate.<init>(Aggregate.java:175)}}
> {{ at
> org.apache.calcite.rel.logical.LogicalAggregate.<init>(LogicalAggregate.java:72)}}
> {{ at
> org.apache.calcite.rel.logical.LogicalAggregate.create_(LogicalAggregate.java:144)}}
> {{ at
> org.apache.calcite.rel.logical.LogicalAggregate.create(LogicalAggregate.java:116)}}
> {{ at
> org.apache.calcite.rel.core.RelFactories$AggregateFactoryImpl.createAggregate(RelFactories.java:328)}}
> {{ at
> org.apache.calcite.tools.RelBuilder.aggregate_(RelBuilder.java:2564)}}
> {{ at
> org.apache.calcite.tools.RelBuilder.aggregate_(RelBuilder.java:2511)}}
> {{ at org.apache.calcite.tools.RelBuilder.aggregate(RelBuilder.java:2348)}}
>
> I think it is either missing {{permute}} or assert should compare
> {{cardinality}} instead of {{length.}} Because it compares field index? to
> number of fields which looks like nonsense to me.
