spring - Relation table1_table2 does not exist Postgres -

i working using spring-mvc , hibernate. have 2 tables in database, table1 , table2. table1 has onetomany relationship table2. when run application query delete row table1 , children table2, error saying, relation table1_table2 not exist.

code : @table(name="table1") class user{     @onetomany     public set<accounts> accounts;     //remove method      query query = session.createquery("from user u left join fetch u.accounts u.id="+id)      //then use loop go through accoutns , remove accounts. } @table(name="table2") class accounts{     @manytoone     public user user; } 

@onetomany is unidirectional relationship can using jpa only. need replace following line onetomany.

@onetomany(mappedby="user",cascade = cascadetype.all, orphanremoval = true)
