我有* .hbm.xml
...
<id name="id" type="java.lang.Integer" column="col1"/>
<map name="myMap" table="table1" cascade="delete" lazy="false">
<key column="col1" />
<composite-map-key class="MyCompositeKey">
<key-property name="komp_key1" column="komp_key1"></key-property>
<key-property name="komp_key2" column="komp_key2"></key-property>
</composite-map-key>
<many-to-many column="col2" class="MyClass" />
</map>
...
结果我有这个约束:
CONSTRAINT relations_pkey PRIMARY KEY (entity_id, attribute_idv, entity_val)
我可以有这个约束:
CONSTRAINT relations_pkey PRIMARY KEY (entity_id, attribute_idv, entity_val, col2)
我可以将col2添加到组合键吗?
