Resolves #10716 Also add test for #10974

maumar · 2018-03-09T00:46:51Z

problem is that we add orderby group key clause to the query. When we compile include we project order by clauses in the inner query (one being qsre). We should optimize group by entity, to group by entity key instead.

maumar · 2018-03-09T00:53:12Z

assigning to @smitpatel since he is working on entity equality improvement currently

smitpatel · 2018-03-09T00:55:05Z

Hold on!
We cannot convert group by entity to group by entity key, if we have to return back the groups.

maumar · 2018-03-09T00:59:49Z

Ah right, I guess we can just recognize we are about to order by qsre and order by key instead.

smitpatel · 2018-03-09T01:01:09Z

Further entity equality deals with equality only and wouldn't process just a qsre in ordering. Perhaps include pipeline at some place needs to convert QSRE to key access while constructing collection query model since AnonymousObject cannot hold a qsre.

maumar · 2018-03-09T01:06:25Z

or we could do that broadly, in OptimizeQueryModel - we just need to convert orderby qsre into orderby pk before RewriteCollectionQueries

smitpatel · 2018-03-09T05:06:38Z

We can certainly do that more broadly. Right now we have piece of code in SqlTranslatingExpressionVisitor which translates QSRE to PK access when not in projection. Perhaps we could evaluate that code path and convert those to PK access during QM rewrite itself.
