---------------------------------
Labels: sub-query (was: )
> AssertionError in ReduceExpressionsRule on multi-column IN sub-query
> --------------------------------------------------------------------
>
> Key: CALCITE-1479
> URL: https://issues.apache.org/jira/browse/CALCITE-1479
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.10.0
> Reporter: Gian Merlino
> Assignee: Julian Hyde
> Labels: sub-query
> Fix For: 1.11.0
>
>
> See also https://github.com/apache/calcite/pull/317. This seems to be related
> to visiting subqueries without accounting for the fact that they might push
> multiple constancys on the stack.
> The assertion error I'm getting in my code is from the sql,
> {code}
> SELECT * FROM s.foo
> WHERE (dim1, dim2) IN (
> SELECT dim1, dim2 FROM (
> SELECT dim1, dim2
> FROM s.foo
> GROUP BY dim1, dim2
> )
> )
> {code}
> and the stack trace is,
> {noformat}
> java.lang.AssertionError: Internal error: Error while applying rule
> ReduceExpressionsRule(Filter), args
> [rel#8:LogicalFilter.NONE.[](input=rel#7:Subset#0.NONE.[],condition=IN($2,
> $3, {
> LogicalProject(DIM1=[$0], DIM2=[$1])
> LogicalAggregate(group=[{0, 1}])
> LogicalProject(DIM1=[$2], DIM2=[$3])
> DruidQueryRel(dataSource=[foo])
