> in derby concat with input parameter needs a cast, otherwise becomes long varchar and

> (NOTE:already done if concat is inside substring eg. substring(concat(xxx,yyy),n,m)
> EJBQL:
> select d from EmpBean e left join e.dept d where concat(d.name, 'ahmad') = 'AhmadDept'

>  
> OPENJPA ERROR OR SQL PUSHDOWN:
> Comparisons between 'LONG VARCHAR' and 'LONG VARCHAR' are not supported. {SELECT t1.deptno,
t1.budget, t1.mgr_empid, t1.name, t1.reportsTo_deptno FROM EmpBean t0 LEFT OUTER JOIN DeptBean
t1 ON t0.dept_deptno = t1.deptno WHERE ((t1.name||?) = ?)} [code=30000, state=42818] 
> SUGGESTED SQL PUSHDOWN:
> select t1.deptno, t1.name FROM EmpBean t0 LEFT OUTER JOIN DeptBean t1 ON t0.dept_deptno
= t1.deptno WHERE (cast((t1.name||?) as Varchar(1000))) = ?  {String ahmad, String AhmadDept}
