The = and <> operators should be supported on CLOBs.
----------------------------------------------------
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
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.
