Can't use distinct in Oracle with BLOB/CLOB column -------------------------------------------------- Key: HHH-3606 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3606 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.2.6 Environment: Oracle 9i Reporter: Julien HENRY Problem: Oracle doesn't support distinct when a row is BLOB/CLOB. The resulting error is: ORA-00932: inconsistent datatypes: expected - got CLOB I got this error when trying to filter root entity (see FAQ: http://www.hibernate.org/117.html#A12). It is not really an Hibernate bug, much likely an Oracle limitation. But perhaps an entry may be added in the FAQ, or perhaps some workaround may be found to not use SQL distinct keyword when a BLOB/CLOB is involved in the query.
