QueryTest - PostgreSQL - "ERROR: operator does not exist: character varying = bytea" ------------------------------------------------------------------------------------ Key: EJB-404 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-404 Project: Hibernate Entity Manager Issue Type: Patch Components: EntityManager Environment: PostgreSQL and Entity Manager Reporter: Juraci Paixao Krohling Assignee: Juraci Paixao Krohling Attachments: QueryTest_2.diff Test org.hibernate.ejb.test.QueryTest#testIsNull fails due to this query: select i from Item i where (i.descr is null and :descr is null) or i.descr = :descr When changing the query to what it reads below, it works properly: select i from Item i where i.descr = :descr or (i.descr is null and :descr is null) As this happened only with PostgreSQL, I assume this is an issue with either the driver or with the database itself. Will dig into pgsql's site to find out more about this issue. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
