151 | @SequenceGenerator and single id in whole databaseHi, I have a question about @SequenceGenerator. I have separate @SequenceGenerator in each ... classes: By using multiple @SequenceGenerator and/or @TableGenerator definitions (with different name ... the part about strategy type. Each of my model class got following annotations: @SequenceGenerator |
86 | javax.persistence.SequenceGeneratorjavax.persistence Annotation SequenceGenerator Target: Classes and fields (including property get methods) Defines a primary key generator that may be referenced by name when a generator element ... to the persistence unit (across all generator types). Example: @SequenceGenerator(name="EMP_SEQ |
83 | SequenceGenerator.sequenceNameAnnotation Element javax.persistence.SequenceGenerator String sequenceName (Optional) The name of the database sequence object from which to obtain primary key values. Defaults to a provider-chosen value. Default value: "" Since: JPA 1.0 |
83 | SequenceGenerator.schemaAnnotation Element javax.persistence.SequenceGenerator String schema (Optional) The schema of the sequence generator. Default value: "" Since: JPA 2.0 |
83 | SequenceGenerator.nameAnnotation Element javax.persistence.SequenceGenerator String name (Required) A unique generator name that can be referenced by one or more classes to be the generator for primary key values. Since: JPA 1.0 |
83 | SequenceGenerator.initialValueAnnotation Element javax.persistence.SequenceGenerator int initialValue (Optional) The value from which the sequence object is to start generating. Default value: 1 Since: JPA 1.0 |
83 | SequenceGenerator.catalogAnnotation Element javax.persistence.SequenceGenerator String catalog (Optional) The catalog of the sequence generator. Default value: "" Since: JPA 2.0 |
83 | SequenceGenerator.allocationSizeAnnotation Element javax.persistence.SequenceGenerator int allocationSize (Optional) The amount to increment by when allocating sequence numbers from the sequence. Default value: 50 Since: JPA 1.0 |
