[jira] Commented: (AMQ-660) Add support for MaxDB

JIRA jira@apache.org
    [ https://issues.apache.org/activemq/browse/AMQ-660?page=comments#action_35945 ]

Johan Hallgren commented on AMQ-660:
------------------------------------

MaxDB does support subselects. When I run the SQL statement manually, I do get the same error as in the log output. That error code maps to "System error" per the MxDB documentation, so there's not much more info to be gained there.

FYI, when I create two smaller tables like below, the statement exexutes successfully:

create table activemq_msgs
(
expiration integer,
id integer,
container varchar(10) ascii
)
//
create table activemq_acks
(
last_acked_id integer,
container varchar(10) ascii
)

Hiram, if you could point me to the structure of the actual activemq_msgs and activemq_acks tables, I can ask on the MaxDB mailing list and maybe get some hints on the issue. Judging by the highlighting in MaxDB's SQL client, I thought that "container" may be a reserved word, but if that were the issue, there'd be another error thrown, and my above experiment wouldn't have worked either.
