liu ming commented on TRAFODION-2047:
-------------------------------------
As Hans correctly pointed out, it is hard to support 'INTERSECT ALL' at
present, so this JIRA will only add support for 'INTERSECT' or 'INTERSECT
DISTINCT', and raise syntax error for 'INTERSECT ALL'
A new JIRA will be created to cover 'INTERSECT ALL' later.
> add SQL syntax support to INTERSECT
