Set entity in HQL query without prefix -> incorrect SQL ------------------------------------------------------- Key: HHH-1286 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1286 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.1 Environment: PostgreSQL 8.0.1 Reporter: Ronald Wildenberg Assignee: Steve Ebersole Priority: Minor Fix For: 3.1.1 Attachments: hibernate.cfg.xml, model.zip Suppose two entities: Term and Indeling with: Term.java: private Indeling indeling; @ManyToOne(cascade = { CascadeType.REFRESH }, optional = false, fetch = FetchType.EAGER) @JoinColumn(name = "indeling_id") public Indeling getIndeling() { return indeling; } Indeling.java: private Set<Term> termen = new HashSet<Term>(); @OneToMany(mappedBy = "indeling", cascade = { CascadeType.REMOVE }) public Set<Term> getTermen() { return termen; } and a HQL query in package-info.java: "from Term where indeling = :indeling" Hibernate generates an SQL statement with the following where clause: "where indeling=?". The join column, however, is indeling_id. A workaround for this issue is to change the HQL query to: "from Term term where term.indeling = :indeling", using an alias. Attached you will find model.zip (with Term.java, Indeling.java and package-info.java) and hibernate.cfg.xml.
