Fellow sufferers!
I am getting an error on my SQL in ALM (see buttom). The problem is related to the very last ON... statement.
The strange thing is, if I replace
FIRST.ID2 = SECOND.RT_FROM_REQ_ID
with
FIRST.ID2 = '0' AND SECOND.RT_FROM_REQ_ID = '0'
then the SQL executes without error (but obviously with another result).
Can anynóne propose a reason?!
Total statement:
SELECT *
FROM
(
SELECT FIRST.NAME ID1, FIRST.TEXT Requirement1, SECOND.RQ_REQ_NAME ID2, SECOND.RQ_USER_29 Requirement2
FROM
(
SELECT SECOND.ID, SECOND.NAME, SECOND.TEXT, SECOND.TOID
FROM
(
SELECT SECOND.RQRL_REQ_ID ID
FROM
(
SELECT *
FROM RELEASES
where REL_ID = @Release@
) FIRST
INNER JOIN
REQ_RELEASES SECOND
ON FIRST.REL_ID = SECOND.RQRL_RELEASE_ID
) FIRST
INNER JOIN
(
select FIRST.ID ID, FIRST.NAME, FIRST.TEXT, REQ_TRACE.RT_TO_REQ_ID TOID
from
(
SELECT rq_req_id ID, REQ.RQ_REQ_NAME NAME, REQ.RQ_USER_29 TEXT
FROM req
where rq_req_id not in
(
select rt_to_req_id
from req_trace
)
AND rq_type_id <> 1 AND rq_type_id <> 101
) FIRST
LEFT JOIN
REQ_TRACE
ON
FIRST.ID = REQ_TRACE.RT_FROM_REQ_ID
) SECOND
ON FIRST.ID = SECOND.ID
) FIRST
LEFT JOIN
REQ SECOND
ON FIRST.TOID = SECOND.RQ_REQ_ID
) FIRST
LEFT JOIN
REQ_TRACE SECOND
ON
FIRST.ID2 = SECOND.RT_FROM_REQ_ID
