>                 Key: CALCITE-5412
>                 URL: https://issues.apache.org/jira/browse/CALCITE-5412
>             Project: Calcite
>          Issue Type: Bug
>    Affects Versions: 1.32.0
>            Reporter: Leonid Chistov
>            Priority: Trivial
>
> CUBE clause seems to be not supported in MYSQL5 in any form 
> ([https://dev.mysql.com/doc/refman/5.7/en/group-by-modifiers.html]), but 
> there is no check for that in Calcite.
> Thus, SQL statement with CUBE clause may be erroneously generated by JDBC 
> adapter for MySQL 5 dialect, causing syntax error issue later on.
