Clustering is really static i.e. it's done and after it any inserts/updates start spoiling the table again. So I guess theanswer is no. Maybe you can create a procedure that does CLUSTER and then recreates the indeces and whatever else youlose in the process. cheers, thalis On Fri, 15 Jun 2001, Dariusz Pietrzak wrote: > > It's done with CLUSTER indeed.
