@Repeatable(value=NamedStoredProcedureQueries.class) @Target(value=TYPE) @Retention(value=RUNTIME) public @interface NamedStoredProcedureQuery
The NamedStoredProcedureQuery
annotation can be applied to an
entity or mapped superclass.
The name
element is the name that is passed as an argument to the
EntityManager.createNamedStoredProcedureQuery(java.lang.String)
method to create an executable StoredProcedureQuery
object.
Names are scoped to the persistence unit.
The procedureName
element is the name of the stored procedure in
the database.
The parameters of the stored procedure are specified by the
parameters
element. All parameters must be specified in the order in
which they occur in the parameter list of the stored procedure.
The resultClasses
element refers to the class (or classes) that are
used to map the results. The resultSetMappings
element names one or
more result set mappings, as defined by the SqlResultSetMapping
annotation.
If there are multiple result sets, it is assumed that they will be
mapped using the same mechanism — e.g., either all via a set of
result class mappings or all via a set of result set mappings. The
order of the specification of these mappings must be the same as
the order in which the result sets will be returned by the stored
procedure invocation. If the stored procedure returns one or more
result sets and no resultClasses
or resultSetMappings
element is specified, any result set will be returned as a list of type
Object[]. The combining of different strategies for the mapping of
stored procedure result sets is undefined.
The hints
element may be used to specify query properties and
hints. Properties defined by this specification must be observed by
the provider. Vendor-specific hints that are not recognized by a
provider must be ignored.
All parameters of a named stored procedure query must be specified
using the StoredProcedureParameter
annotation.
