【问题描述】：
由于某种原因，我无法执行此查询，因为我遇到了错误：
Token ( was not valid. Valid tokens: , FROM INTO.
我在 DB2 中运行它，我认为这发生在第二个 with/as 的第一行 ) , A AS ( SELECT
我哪里错了？
WITH
RES (PRODUCT_ID, JOB_STATUS, JOB_STATUS_TIME) AS
(
select
T1.NAME,
t2.PRODUCT_id as PRODUCT_ID,
t3.product_id,
t3.created_at,
t5.name as JOB_STATUS,
t4.row_created_timestamp as JOB_STATUS_TIME ,
t3.expiration_timestamp
from schema.PRODUCT T1
inner join schema.PRODUCT_to_product T2
on t1.PRODUCT_id = t2.PRODUCT_id
inner join schema.product t3
on t2.product_id = t3.product_id
inner join schema.product_to_job_statust t4
on t3.product_id = t4.product_id
inner join schema.job_statust t5
on t4.job_statust_id = t5.job_statust_id
where t3.job_typet_id = 2
and t3.created_at >= '2019-09-20'
and t5.name <> 'D'
order by t1.name,t3.product_id
)
, A AS
(
SELECT
PRODUCT_ID, JOB_STATUS
, JOB_STATUS_TIME
, LEAD (JOB_STATUS_TIME) OVER (PARTITION BY PRODUCT_ID ORDER BY JOB_STATUS_TIME) AS JOB_STATUS_TIME_NEXT
FROM RES
)
SELECT
PRODUCT_ID
, COUNT(CASE JOB_STATUS WHEN 'O' THEN 1 END) AS CREATED
, COUNT(CASE JOB_STATUS WHEN 'C' THEN 1 END) AS COMPLETED
, COUNT(CASE JOB_STATUS WHEN 'X' THEN 1 END) AS CANCELLED
, SUM
(
CASE JOB_STATUS WHEN 'P' THEN
(DAYS(JOB_STATUS_TIME_NEXT) - DAYS(JOB_STATUS_TIME)) * 86400
+ MIDNIGHT_SECONDS(JOB_STATUS_TIME_NEXT) - MIDNIGHT_SECONDS(JOB_STATUS_TIME)
END
) / 60 AS ACTIVE_MINUTES
FROM A
GROUP BY PRODUCT_ID;
【问题讨论】：
-
删除
order by。它不属于 CTE（或子查询）。我不知道 DB2 是否会检查，但它也可能是错误的原因。 -
我确实在您提出的那个主体上删除了它，但不幸的是它没有解决这个问题
-
您的
RES字段列表与其SELECT语句不匹配，并且您的A查询根本没有字段列表... -
其实除非运行递归CTE，否则不需要字段列表。
-
因此，即使将字段列表添加到
A或从RES中删除，我也会遇到相同的错误。这也在 IBM iSeries 版本 7 上
