[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-345) compound primary/foreign key problems with nulls and NamedQuery parsing

compound primary/foreign key problems with nulls and NamedQuery parsing ----------------------------------------------------------------------- Key: EJB-345 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-345 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.3.2.GA Environment: Hibernate core 3.2.6.ga, Hibernate EntityManager 3.3.2.GA, Hibernate Validator 3.0.0.GA, Hibernate Annotations 3.3.1.GA MySQL 5.0.45 / driver jar mysql-connector-java-3.1.12-bin Reporter: Reid Hartenbower Attachments: test-src.zip Hi. I have Item, Container, and Specification entities that subclass NamedThing. NamedThing uses a compound primary key which is a two-long representation of a UUID. Item has a @ManyToOne with Container and Specification, and Specification has a <String,String> properties map. Two problems, first: queries like "select distinct object(i) from Item i where i.specification.properties[:key] = :value" produce parse errors (these are the commented-out NamedQueries in Item); the complaint is '.' character after specification queries like "select distinct object(i) from Item i, Specification s where i.container is null and i.specification = s and s.properties[:key] is null" in TestItem.java:61 do parse successfully but produce the exception whose stack trace is in TestItemStackTrace.txt. The hibernate sql is in hibernate-sql-output.txt; the complaint is 'java.sql.SQLException: Operand should contain 1 column(s)' Thanks, Reid
