[teiid-issues] [JBoss JIRA] Resolved: (TEIID-251) Support SQL 2003 order by with expressions
[
https://jira.jboss.org/jira/browse/TEIID-251?page=com.atlassian.jira.plug...
]
Steven Hawkins resolved TEIID-251.
----------------------------------
Resolution: Done
Finished the work to add support for order by expression by using the rewriter. At a
later time it would be good to add full support through the planner/processor/connector
layer.
Support SQL 2003 order by with expressions
------------------------------------------
Key: TEIID-251
URL: https://jira.jboss.org/jira/browse/TEIID-251
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Affects Versions: 6.0.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Optional
Fix For: 7.0
Attachments: sort_expression.patch
Original Estimate: 2 days
Remaining Estimate: 2 days
Defect Tracker #25000: SQL 2003 allows the order by clause to contain expressions instead
of just simple simple symbol names. Since we already support expressions in the group by
clause (which is actually against the SQL spec), it would make since to support
expressions in the order by as well.
