mysql - Hibernate native sql table not found error -


i'm trying run native sql delete in hibernate session, exception complaining table alias. if run sql query in sql client, works fine.

string sql = 'delete c child c join parent p on c.parent_id=p.id p.some_id = :someid' sqlquery deletequery = sessionfactory.currentsession.createsqlquery(sql) deletequery.setparameter( 'someid', some.id.longvalue() ) deletequery.executeupdate()

exception thrown in unit test:

[main] error util.jdbcexceptionreporter  - table "c" not found; sql statement:  delete  c  child  c  join parent p on c.parent_id=p.id p.some_id = ?

any suggestions on why doesn't work through hibernate?

(edited)

using names of tables better.

string sql = 'delete child child inner join parent on child.parent_id = parent.id parent.some_id = :someid';

add

this example code (my) adapted you:

...  public boolean eliminar( child some_id ) {     boolean result  = false;     session session = null;     transaction rs  = null;      try     {         session = sessionfactory.opensession();         rs = session.begintransaction();         rs.settimeout(5);          string query_string = "delete child child inner join parent on child.parent_id = parent.id parent.some_id = :someid";         query_string.setparameter( 'someid', some_id );         query q = session.createquery(query_string);         q.executeupdate();          rs.commit();          result = true;     }     catch(runtimeexception e)     {         try         {             rs.rollback();         }         catch(runtimeexception rbe)         {             system.out.println(rbe.getmessage());         }         system.out.println(e.getmessage());     }         {         session.close();     }     return result; } ...
