Annotation Interface ColumnResult

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

The name() 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.
