Subject [jira] [Resolved] (ASTERIXDB-1294) FOR clause should return an Unordered collection of elements/records
Date Thu, 11 Aug 2016 04:04:20 GMT

     [ https://issues.apache.org/jira/browse/ASTERIXDB-1294?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yingyi Bu resolved ASTERIXDB-1294.
----------------------------------
    Resolution: Won't Fix

Both "For" clauses in AQL and Select queries in SQL++ return an ordered list. IMO, "ordered
list" doesn't mean the list is ordered by some keys, but just mean insertion order (which
could be non-deterministic, e.g., result distribution) is maintained and index-based access
(e.g., positional variables and index-access expressions) is supported.

> The return type for the "FOR" clause from a data type perspective should be an "unordered"
collection (Similar to SQL's "SELECT" statement). However, currently it is considered as an
"ordered" collection.
