> Key: DERBY-5241
> URL: https://issues.apache.org/jira/browse/DERBY-5241
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.9.0.0
> Reporter: Rick Hillegas
> Labels: derby_triage10_9
>
> According to the 2008 SQL Standard, part 2, section 4.2.1, the = and <>
> operators should be supported when comparing CLOBs. The following script
> shows this defect:
> connect 'jdbc:derby:memory:db;create=true';
> create table t( a clob, b clob );
> select * from t where a = b;
> select * from t where a <> b;
> A partial workaround would be to cast the CLOBs as VARCHAR( 32672 ). This
> would work for small CLOBs.
