Well, you got it almost right!

The first "login" must be the physical attribute in the table, i.e. the
DbAttribute. You could also use the ObjAttribute name with a
binary(Path)Exp.

Here "login" also needs to be the DbAtrribute name; unfortunately the
ObjAttribute name won't work. :(

This should be something like:
DefaultOperationObserver observer = new DefaultOperationObserver();
ctxt.performQuery(q, observer);
if (observer.hasExceptions())
{
// handle error
log.debug("Error: " + observer.getQueryExceptions());
}
Directly executing queries basically works (and is very useful, e.g. for
mass updates) but is IMHO still too confusing and inconsistent; this needs
to be addressed for 1.1.
