[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-5171) Allow usage of standalone @JoinFormula annotation

Allow usage of standalone @JoinFormula annotation ------------------------------------------------- Key: HHH-5171 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5171 Project: Hibernate Core Issue Type: Improvement Components: annotations Affects Versions: 3.6 Reporter: Sharath Reddy Assignee: Sharath Reddy Fix For: 3.6 If there is a single-column join (based on formula) between 2 entities, it is overkill to wrap the @JoinFormula within a @JoinColumnsOrFormulas annotation: @ManyToOne @JoinColumnsOrFormulas( { @JoinColumnOrFormula(formula=@JoinFormula(value="SUBSTR(product_idnf, 1, 3)", referencedColumnName="product_idnf")) }) The above annotation is powerful, because it gives us the flexibility of using an arbitrary combination of columns and formulas for the join, but in this case it is redundant. If would be easier to just specify like this: @ManyToOne @JoinFormula(value="SUBSTR(product_idnf, 1, 3)", referencedColumnName="product_idnf")) })
