- What did you do?
If possible, provide a recipe for reproducing the error.
CREATE TABLE `t1` (
`period_name` varchar(24) DEFAULT NULL ,
`period_id` bigint(20) DEFAULT NULL ,
`starttime` bigint(20) DEFAULT NULL
);
CREATE TABLE `t2` (
`bussid` bigint(20) DEFAULT NULL,
`ct` bigint(20) DEFAULT NULL
);
select
a.period_name,
b.date8
from
(select * from t1) a
left join
(select bussid,date(from_unixtime(ct)) date8 from t2) b
on
a.period_id = b.bussid
where
datediff(b.date8, date(from_unixtime(a.starttime))) >= 0;
- What did you expect to see?

Empty set (0.01 sec)
- What did you see instead?
No result and eventually panic caused by stack overflow.
