Partition Pruning did not take place for the below query after I executed the
"refresh table metadata command"
{code}
explain plan for
select
l_returnflag,
l_linestatus
from
`lineitem/2006/1`
where
dir0=1 or dir0=2

The logs did not indicate that "pruning did not take place"
Before executing the refresh table metadata command, partition pruning did take
effect
