Based in my few experience in histograms I decided to run this command
EXEC DBMS_STATS.GATHER_SCHEMA_STATS( OWNNAME=>'DAZ', ESTIMATE_PERCENT=>100
METHOD_OPT=>'FOR ALL COLUMNS SIZE SKEWONLY');
with the only goal of giving more information to CBOI
didn't tested if this really gives a improvement, but I read something in
some place that says it does.
I don't remember where.
Any comment about the previous command?
