@Target({}) @Retention(RUNTIME) public @interface ColumnResult
Used in conjunction with theSqlResultSetMapping
,NamedNativeQuery
, orConstructorResult
annotation to map a column of the SELECT list of a SQL query.The

element references the name of a column in the SELECT list — i.e., column alias, if applicable. Scalar result types can be included in the query result by specifying this annotation in the metadata.Example: {@snippet : Query q = em.createNativeQuery( "SELECT o.id AS order_id, " + "o.quantity AS order_quantity, " + "o.item AS order_item, " + "i.name AS item_name, " + "FROM Order o, Item i " + "WHERE (order_quantity > 25) AND (order_item = i.id)", "OrderResults");
