After Rebuilding the Indexes
the LAST_ANALYZED-Attribute is set to NULL,
The Statistics for the index is gone.
Problem is that the CBO goes grazy with indexes when
no statistics is available ( FULL-TABLE-SCANS ).
Is there a trick to rebuild the index without dropping the old statistics ( till a new gather of stats ) ?
