JPA Hibernate ManytoMany Foreign key as partial primary key
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I'm having trouble mapping the association between these 2 tables using JPA:
CREATE TABLE SEARCHKEY (
internalId int not null
keyType varchar(6) not null
keyId varchar(36) not null
...
PRIMARY KEY (keyId, keyType, internalId),
);
CREATE TABLE DECISION(
decisionId int not null
internalId int not null
decisionResult varchar(6) not null
...
PRIMARY KEY (decisionId),
);
Currently a searchKey can have multiple Decisions and a Decision can have several searchKeys, so I'm thinking of a ManyToMany association however I only need the SearchKey->Decision association.
I want to associate both entities using internalId as a foreign key but I'm currently having trouble since the internalId is part of the embeddedId in SearchKey.
How can I write these entities using JPA?
Thanks in advance!
