Hello friends,



Can anyone please tell me how to drop (only) histograms on a column?



Ours is an OLTP application.


Few of our queries go really bad when there are histograms.
We need only NUM_DISTINCT, LOW_VALUE, HIGH_VALUE, DENSITY, NUM_NULLS,
AVG_COL_LEN in the data dictionary.



Or rather, how to retain only the above statistics and drop rest stats?



The procedure DBMS_STATS.DELETE_COLUMN_STATS does not have any option
to remove/add only selected statistics.
