Sandeep Tamhankar commented on HHH-1423:
----------------------------------------

I believe I'm running into a different flavor of this issue.  Here's some HQL that didn't quite do what I wanted, but it satisfied most of my needs:

select foo
from Foo foo 
  left join foo.bar bar1 
  left join foo.baz baz1
  left join foo.bar bar2
  left join foo.baz baz2
where ((bar1.name = :param_1 and bar1.some_field = :param_2)
         or (baz1.name = :param_1 and baz1.some_field = :param_2))
     and ((bar2.name = :param_3 and bar2.some_field = :param_4)
         or (baz2.name = :param_3 and baz2.some_field = :param_4))

In this example, foo.bar and foo.baz are collections.

This is a generated query, but it doesn't quite fit the structure I want because sometimes I want to find objects Foo whose collections bar and baz don't contain elements with some name.  I thought I could get there like this:

select foo
from Foo foo 
  left join foo.bar bar1 with bar1.name = :param_1
  left join foo.baz baz1 with baz1.name = :param_1
where bar1.name is null and baz1.name is null;

which means my first query would look like this:

select foo
from Foo foo 
  left join foo.bar bar1 with bar1.name = :param_1
  left join foo.baz baz1 with baz1.name = :param_1
  left join foo.bar bar2 with bar2.name = :param_3
  left join foo.baz baz2 with baz2.name = :param_3
where ((bar1.some_field = :param_2)
         or (baz1.some_field = :param_2))
     and ((bar2.some_field = :param_4)
         or (baz2.some_field = :param_4))

basically, just move the 'name' references in the predicate up to the join clause.  This failed (returned no results).  However, when I switched the join order to do all of the bar's before baz's, it worked.  I then tried all baz's before bar's, and that worked, too.

select foo
from Foo foo 
  left join foo.bar bar1 with bar1.name = :param_1
  left join foo.bar bar2 with bar2.name = :param_3
  left join foo.baz baz1 with baz1.name = :param_1
  left join foo.baz baz2 with baz2.name = :param_3
where ((bar1.some_field = :param_2)
         or (baz1.some_field = :param_2))
     and ((bar2.some_field = :param_4)
         or (baz2.some_field = :param_4))

Thus, I think the parameter parsing issue that this JIra issue encompasses does apply to me.
