@Target(value=TYPE) @Retention(value=RUNTIME) public @interface NamedStoredProcedureQuery
Specifies and names a stored procedure, its parameters, and its result type.
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(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.
