Hello Experts,

I have a strange query(select statement) some times it finish in 1 min and some times it will take more than 3 hours.

No changes at DB level

No hash value changed

DB is running fine without any issues.

Out of 6 tables 4 tables going for full table scan.But the same query some times will finish in a minute and some time it takes more than 3 hours.

Please advise,

Thanks a lot in advance.

Howdy, Stranger!
