TimesTen and subqueries

Question

Does TimesTen support subqueries? What can I do, if not?

Answer 1

I really have other tables :)
T1 is
CREATE USERMANAGED CACHE GROUP "CGRP_AUTO_CALLS"
AUTOREFRESH MODE INCREMENTAL INTERVAL 5 MINUTES
STATE ON
FROM
"KVSTR"."AUTO_CALLS" (
"ATCL_ID" NUMBER(10) NOT NULL,
"SRLS_SRLS_ID" NUMBER(10),
"ATTP_ATTP_ID" NUMBER(10),
"CLNT_CLNT_ID" NUMBER(10),
"MSISDN" VARCHAR2(15 BYTE),
"CALL_DATE" DATE,
"DEL_USER" VARCHAR2(20 BYTE),
PRIMARY KEY("ATCL_ID"), READONLY
WHERE (DEL_USER IS NULL);
T2 is
CREATE USERMANAGED CACHE GROUP "CGRP_AUTO_ATTEMPTS"
AUTOREFRESH MODE INCREMENTAL INTERVAL 5 MINUTES
STATE ON
FROM
"KVSTR"."AUTO_ATTEMPTS" (
"ATAT_ID" NUMBER(10) NOT NULL,
"ATCL_ATCL_ID" NUMBER(10),
PRIMARY KEY("ATAT_ID"), READONLY
And query is
select
AUTO_CALLS.CLNT_CLNT_ID,
nvl(T.ATAT_ID_COUNT, 0)
from
AUTO_CALLS,
(select
AUTO_ATTEMPTS.ATCL_ATCL_ID,
count(AUTO_ATTEMPTS.ATAT_ID) ATAT_ID_COUNT
from
AUTO_ATTEMPTS
group by AUTO_ATTEMPTS.ATCL_ATCL_ID
) T
where (AUTO_CALLS.ATCL_ID = T.ATCL_ATCL_ID(+))
and (AUTO_CALLS.DEL_USER is null)
I cann't modify these tables or create some indexes, because these are commercial ORACLE tables.
