[hibernate-issues] [Hibernate-JIRA] Moved: (HHH-3184) Erroneous SQL goes to Oracle when using operator IN with composite key

Erroneous SQL goes to Oracle when using operator IN with composite key ---------------------------------------------------------------------- Key: HHH-3184 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3184 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.6 Environment: Hibernate 3.2.6 Hibernate Annotations 3.3.1.CR1 Hibernate EntityManager 3.3.2.CR1 Oracle 10g Reporter: botWi entity Footballer has composite primary key defined via @IdClass and @Id getters (see http://www.hibernate.org/hib_docs/annotations/reference/en/html_single/#e...) entity Goal has property 'footballer' defined via @ManyToOne query select g from Goal g where g.footballer in (select f from Footballer f where f.age=22) is translated to erroneous SQL select goal0_.id as col_0_0_ from tgoal goal0_ where (goal0_.fb_firstname, goal0_.fb_lastname) in (select (footballer1_.fb_firstname, footballer1_.fb_lastname) from tfootballer footballer1_ where footballer1_.age=22) it's strange, but the slightly modified query select g from Goal g where g.footballer.id in (select f.id from Footballer f where f.age=22) is translated to valid SQL select goal0_.id as col_0_0_ from tgoal goal0_ where (goal0_.fb_firstname, goal0_.fb_lastname) in (select footballer1_.fb_firstname, footballer1_.fb_lastname from tfootballer footballer1_ where footballer1_.age=22)
