I have the following code to make sure that the query does not acquire an exclusive lock on the database tables.

query=session.createQuery("select count(*) from prh a " +
" where a.prn = :form_nbr " +
" and UPPER(a.gsi) = thr");
query.setLong("form_nbr",form_nbr);
query.setString("othr","OTHR");
query.setLockMode("a",LockMode.NONE);
The code compiles and builds fine, but when I run it, it throws the following exception:

exception: alias a not found

I am adding the LockMode.None to the query to avoid any kind of table locking as there is some other transaction that is expected to update the same row.

Any help in this regard with be greatly appreciated.
