> Key: TRAFODION-2730
> URL: https://issues.apache.org/jira/browse/TRAFODION-2730
> Project: Apache Trafodion
> Issue Type: Bug
> Reporter: Anoop Sharma
> Assignee: Suresh Subbiah
> Priority: Minor
>
> run the following script from sqlci to reproduce this issue on trafodion
> master branch:
> create table if not exists tloop(a int);
> control query default INFER_CHARSET 'on';
> select 'a' from tloop;
> drop table tloop;
> select 'a' from tloop; -- this select will loop
> Last 'select' will loop in method QCache∷free_entries_with_QI_keys.
> It is caused by method Qcache∷deCache not removing the specified entry.
>
> This issue happens if infer_charset cqd is on.
> It could be that the cache key being computed is different with and without
> this cqd.
