Hi Mag,

As long as the doc (http://db.apache.org/derby/docs/10.1/ref/rrefjdbc96386.html)
says true,
you cannot index the CLOB column.

---here is a snippet of the doc-------------------------
* Restrictions on BLOB, CLOB, (LOB-types): 
LOB-types cannot be compared for equality(=) and non-equality(!=, <>. 
LOB-typed values are not order-able, so <, <=, >, >= tests are not
supported. 
LOB-types cannot be used in indices or as primary key columns. 
DISTINCT, GROUP BY, ORDER BY clauses are also prohibited on LOB-types. 
LOB-types cannot be involved in implicit casting as other base-types. 
--------------------------------------------------------

Regards,
Wolfgang.
