             Summary: Make the Visitor support in CursorNodes support ORDER BY lists, FETCH, and OFFSET clauses
                 Key: DERBY-6263
                 URL: https://issues.apache.org/jira/browse/DERBY-6263
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.11.0.0
            Reporter: Rick Hillegas


If you call treePrint() on a CursorNode, you will see information on ORDER BY, FETCH, and OFFSET clauses. However, these clauses are not visited by CursorNode.acceptChildren(). This looks like an omission. This defect was brought to our attention by this email thread: http://apache-database.10148.n7.nabble.com/Using-ASTParser-and-TreeWalker-for-parsing-SQL-query-td131219.html. You can see the difference in treePrint() and acceptChildren() behavior by running the following query through the ASTParser and TreePrinter tools attached to DERBY-3946:

    select tablename from sys.systables where 1=2 order by tablename;
