Package org.hibernate.annotations
Annotation Type SQLSelect
-
@Target({TYPE,FIELD,METHOD}) @Retention(RUNTIME) public @interface SQLSelect
Specifies a custom SQL query to be used in place of the default SQL generated by Hibernate when an entity or collection is loaded from the database by id. This occurs when:- an association to an entity is fetched lazily,
- a collection is fetched lazily, or
- when an entity is retrieved using
Session.get(java.lang.Class<T>, java.lang.Object)
orEntityManager.find(java.lang.Class<T>, java.lang.Object)
.
The given SQL statement must have exactly the number of JDBC
?
parameters that Hibernate expects, that is, one for each column of:- the primary key, in the case of an entity, or
- the foreign key, in the case of a collection.
Optionally, an explicit result set mapping may be specified. It should have:
- a single
EntityResult
, if the SQL query loads an entity, one-to-many association, or many-to-many association, or - a single
ColumnResult
orConstructorResult
, if the SQL query loads an collection of basic-typed values.
