[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5185) Columns in Formulas not always rewritten, triggers ambiguous column SQL error

Columns in Formulas not always rewritten, triggers ambiguous column SQL error ----------------------------------------------------------------------------- Key: HHH-5185 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5185 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.1 Environment: MySQL Server version: 5.0.51a-3ubuntu5.5 (Ubuntu) Hibernate version 3.5.1-Final Reporter: Chris Wilson Attachments: HibernateJoinFormulaAliasTest.java The attached test case joins an entity with two @Formulas twice. The first @Formula is the algebraic expression "(kittens * 4) + 3", the second is a SQL function "EXTRACT(MONTH FROM birthday)". kittens is rewritten but birthday is not. Because the table is joined twice, MySQL reports the error: {code} com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Column 'birthday' in field list is ambiguous {code} which shows up as: {code} org.hibernate.exception.ConstraintViolationException: could not load an entity: [org.aptivate.hibernate.test.HibernateJoinFormulaAliasTest$House#1] at

left outer join cats cats2x2_ on hibernatej0_.id=cats2x2_.secondHome_id where hibernatej0_.id=? {code} There's no apparent workaround that lets us reference the same column in a formula in a table that's joined twice.
