Merging multiple sorted results missing ordering clauses
---------------------------------------------------------
Key: OPENJPA-495
URL: https://issues.apache.org/jira/browse/OPENJPA-495
Project: OpenJPA
Issue Type: Bug
Components: query
Reporter: Pinaki Poddar
Assignee: Pinaki Poddar
Came across following error while merging multiple sorted result sets:
OrderingMergedResultObjectProvider uses QuereyExpressions.orderingClauses for
its logic to merge results in order. However,
QuereyExpressions.orderingClauses never gets populated while building the
expression by parsing the JPQL query in JPQLExpressionBuilder.
The problem became apparent while merging query results from multiple
databases.
