CALCITE-2183) Depends on [CALCITE-2183|https://issues.apache.org/jira/browse/CALCITE-2183] > subquery leading to a "java.lang.ClassCastException: RexSubQuery cannot be > cast to RexLocalRef" > ----------------------------------------------------------------------------------------------- > > Key: CALCITE-2184 > URL: https://issues.apache.org/jira/browse/CALCITE-2184 > Project: Calcite > Issue Type: Bug > Components: core > Affects Versions: 1.16.0 > Reporter: Alessandro Solimando > Assignee: Julian Hyde > Priority: Minor > > Executing this query Calcite tries to cast the subquery (_RexSubQuery_) to a > local reference (_RexLocalRef_), resulting in a _ClassCastException_. > Here is the query: > {code:sql} > select * > from (values (1, 'a'), (2, 'b'), (3, 'b'), (4, 'c'), (2, 'c')) as t(x, y) > where exists ( > select * > from (values (1, 'a'), (2, 'b')) as v(w, z) > where w < x > ) > {code} > But the same happens with other (similar) queries, such as the following: > {code:sql} > select x > from (values (1, 'a'), (2, 'b')) as t(x, y) > where x <= all ( > select x > from (values (1, 'a'), (2, 'b'), (1, 'b'), (2, 'c'), (2, 'c')) as t(x, y) > ) > {code} > Please note that this problem is "masked" by the issues described in > [CALCITE-2183|https://issues.apache.org/jira/browse/CALCITE-2183], and it can > be reproduced only by "patching" this second. > Below the
