Integrity constraint violation: for Hibernate Insert

[walter wang]

Dear All,

I have tables designed as below, but i always get Caused by: java.sql.SQLException: Integrity constraint violation: SYS_FK_16 table: BOSS in statement [insert into COMPANY (WORKER_ID, WORKER_DEPAT_ID, BOSS_ID, BOSS_DEPAT_ID, COMPANY_ID) values (1, 2, 1, 11, 1)]
at org.hsqldb.Trace.getError(Unknown Source)
for insert record to table Company

Could any one give me some hints ?

CREATE TABLE WORKER (
depat_id int NOT NULL ,
worker_id int NOT NULL,
salary decimal(20,4) NOT NULL,
primary key (depat_id,worker_id)
)

CREATE TABLE BOSS (
depat_id int NOT NULL ,
boss_id int NOT NULL,
salary decimal(20,4) NOT NULL,
primary key (depat_id,boss_id)
)

CREATE TABLE COMPANY(
company_id int NOT NULL PRIMARY KEY,
boss_id int NOT NULL,
boss_depat_id int NOT NULL ,
worker_id int NOT NULL,
worker_depat_id int NOT NULL ,
foreign key (boss_id, boss_depat_id) references BOSS (boss_id,depat_id),
foreign key (worker_id, worker_depat_id) references WORKER (worker_id,depat_id)
)

Is it possible that the Worker and/or Boss records that the Company refers to hasn't been inserted yet?

What is your relationship/association mapping?

Thanks for your reply.
I insert Boss first, then Insert Worker, then Insert Company
Session s= SessionManager.currentSession();
Boss b1=new Boss();
b1.setComp_id(new BossPK(new Integer(1),new Integer(11)));
b1.setSalary(new BigDecimal(7000));

Worker w1=new Worker();
w1.setComp_id(new WorkerPK(new Integer(1),new Integer(2)));
w1.setSalary(new BigDecimal(3000));

Company c=new Company();
c.setBoss(b1);
c.setWorker(w1);
c.setCompanyId(new Integer(1));
HashSet hs=new HashSet();
hs.add(c);
w1.setCompanies(hs);
b1.setCompanies(hs);
s.save(w1);
s.save(b1);
s.save(c);

s.flush();

You should only have to call s.save(c);

and change the cascade from "none" to "all" for the associations from Company to the Boss and Worker.

Thanks for your reply.

I modify work.hbm.xml and boss.hbm.xml cascade=all
I tried many times. save(c) doesnot work. it will have exception,
but if save(w1) and save(b1), it workds. i donot need to save(c).

PS: in work.hbm.xml and boss.hbm.xml to set inverse as true or false
have same result. it has no effects on this case.
