Re: performance question

Many thanks to Wolfgang B. who pointed out the problem to this.
The problem was that one database has histogram data and the other doesn't. I have verified it.

Thanks to all who replied.

That's interesting.
May you run

select column_name, num_distinct, density, histogram, num_buckets
from user_tab_col_statistics
where table_name = 'YOUR_TABLE'

and check stats.
