But the binding values are out of order. Value for ref_no binds with seq_no and value for seq_no binds with ref_no. @OneToMany(fetch = EAGER) @JoinColumns({ @JoinColumn(name = "REF_NO",referencedColumnName = "REF_NO"), @JoinColumn(name = "SEQ_NO",referencedColumnName = "SEQ_NO") }) public Set<InProcessPartyEntity> getParties() { return parties; } Output trace log(incorrect binding): Hibernate: select p1_0.seq_no,p1_0.ref_no,p1_0.party_code,p1_0.party_id from rbi_trade.ot_txn_party p1_0 where (p1_0. *seq_no* ,p1_0. *ref_no* ) in((?,?)) 2023-03-09T08:31:42.540+01:00 TRACE 15588 — [ scheduling-1] org.hibernate.orm.jdbc.bind : binding parameter [1] as [VARCHAR] - [*E313100005323221237*] 2023-03-09T08:31:42.540+01:00 TRACE 15588 — [ scheduling-1] org.hibernate.orm.jdbc.bind : binding parameter [2] as [VARCHAR] - [*001*] In the same entity class I am also using @OnetoOne ( https://github.com/OnetoOne ) annotation with multiple join columns as follows, which works perfectly fine and leads to the correct binding parameters values ` @OneToOne(fetch = EAGER) @JoinColumns({ @JoinColumn(name = "REF_NO",referencedColumnName = "REF_NO"), @JoinColumn(name = "SEQ_NO",referencedColumnName = "SEQ_NO") }) public InProcessWorkUnitEntity getWorkUnit() { return workUnit; } Output trace log (correct binding): Hibernate: select i1_0.ref_no,i1_0.seq_no,i1_0.reg_by from rbi_trade.ot_workunit i1_0 where (i1_0. *ref_no* ,i1_0. *seq_no* ) in((?,?)) 2023-03-09T08:31:42.524+01:00 TRACE 15588 — [ scheduling-1] org.hibernate.orm.jdbc.bind : binding parameter [1] as [VARCHAR] - [*E313100005323221237*] 2023-03-09T08:31:42.525+01:00 TRACE 15588 — [ scheduling-1] org.hibernate.orm.jdbc.bind : binding parameter [2] as [VARCHAR] - [*001*] I am facing this issue since I upgraded to spring boot jpa 3.0.2. I was using version 2.7.2 before where the binds with @OneToMany ( https://github.com/OneToMany ) also worked fine.
