-----------------------------------

             Summary: support ORDER BY clause in GROUP_CONCAT function
                 Key: TRAFODION-2270
                 URL: https://issues.apache.org/jira/browse/TRAFODION-2270
             Project: Apache Trafodion
          Issue Type: Sub-task
            Reporter: liu ming
            Assignee: liu ming


currently, GROUP_CONCAT() in Trafodion cannot recognize order by clause, need 
to support it.

for example:
SELECT student_name,
          GROUP_CONCAT(DISTINCT test_score
                    ORDER BY test_score asc SEPARATOR ' ')
          FROM student
          GROUP BY student_name;
