Description

However, here's a query that works in 10.1.2.1 but not in 10.2.1.1 – database can be assumed to be the same in Derby - 1205

SELECT DISTINCT
ZONE.ZONE_ID ZONE_ID,
PORT.PORT_ID PORT_ID,
ENTITY_TO_PORT.TYPE,
ENTITY_TO_PORT.PREFIX_ID,
ENTITY_TO_PORT.ENTITY_ID,
ENTITY_TO_PORT.DISPLAY_NAME,
ENTITY_TO_PORT.PORT_DISPLAY_NAME,
PORT2ZONE.MEMBER_NAME,
PORT2ZONE.ZONE_MEMBER_ID,
PORT.PORT_NUMBER
FROM
T_RES_ZONE ZONE left outer join T_VIEW_PORT2ZONE PORT2ZONE on
ZONE.ZONE_ID = PORT2ZONE.ZONE_ID left outer join T_RES_PORT PORT on
PORT2ZONE.PORT_ID = PORT.PORT_ID left outer join T_VIEW_ENTITY_TO_PORT ENTITY_TO_PORT on
PORT2ZONE.PORT_ID = ENTITY_TO_PORT.PORT_ID and
PORT2ZONE.ZONE_ID = ENTITY_TO_PORT.ZONE_ID, T_RES_FABRIC FABRIC
WHERE PORT2ZONE.ZONE_ID = ZONE.ZONE_ID and
ZONE.FABRIC_WWN = FABRIC.FABRIC_WWN and
FABRIC.FABRIC_ID = 1

Same db as before.

In 10.2.1.1 it gives the following error (should this be a new issue?)
