java - Hibernate Criteria select using embedded object (tuple) -

-

in case have sql query looks like:

select * event_instance (object_id, object_type) in      (<list of tuples retrieved subquery>);

i want map on hibernate entities , have problem query. mapping looks that:

     @entity      @table(name="event_instance")      public class auditevent {          <other_fields>           @column( name = "object_type", nullable = false)          private string objecttype;           @column( name ="object_id" , nullable = false)          private integer objectid;      }

and second entity:

    @entity     @table(schema = "els" ,name = "acg_objects")     public class acgobject implements serializable{          @id         @column(name = "acg_id")         private string acgid;          @id         @column(name="object_type")         private string objecttype;          @id         @column(name="object_id")         private integer objectid;          <other fields>  }

i run query getting acgobjects , dao i'm getting list thing want query touple using criteria like:

      crit.add(restrictions.in("objecttype,objectid",<list of tuples>);

is possible? trying use @embedded object don't know how construct query it. please help

you can not in standard sql nor using criteria; have split in 2 distinct restrictions or using session.sqlquery() if want use specific rdbms (look @ sql where.. in clause multiple columns explanation)

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
