query generates invalid sql: Column 'id' in where clause is ambiguous --------------------------------------------------------------------- Key: EJB-355 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-355 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.3.2.GA Environment: MySQL 5.0.1 Reporter: sagi mann Entities: @Entity @Inheritance(strategy=InheritanceType.JOINED) //@DiscriminatorColumn(name="classname", discriminatorType=DiscriminatorType.STRING, length=255) public abstract class JoinedBaseClass implements Serializable { @Id @GeneratedValue public Long getId() { return this.id; } public void setId(Long id) { this.id = id; } private Long id; } @Entity //@DiscriminatorValue(value="joinedsubclass1") public class JoinedSubClass1 extends JoinedBaseClass { @Basic public String getSubProp1() { return bp1; } public void setSubProp1(String bp) { this.bp1 = bp; } private String bp1; } Code in EJB em.createQuery("delete from JoinedSubClass1 c where c.id = 3") .executeUpdate(); The generated SQL (from MySQL trace file): create temporary table if not exists HT_JoinedSubClass1 (id bigint not null) insert into HT_JoinedSubClass1 select joinedsubc0_.id as id from JoinedSubClass1 joinedsubc0_ inner join JoinedBaseClass joinedsubc0_1_ on joinedsubc0_.id=joinedsubc0_1_.id where id=3 Note the final 'where' clause. Shouldn't it be where joinedsubc0_.id=3 instead of where id=3 ? When I manually tried to replace the where clause (just to see if the query gives correct output), it works... but Hibernate insists on generating an invalid query. I'm not sure what I need to do in order to instruct Hibernate to generate the correct syntax - this could be a bug.
