Gilles has a good quick way. I have writtten a script to use the algorithm in the ORACLE Administrator's manual to calculate (really estimate) thhe actual size for the data in a table. I have found it quite good and use it regularly. See the posting Free ORACLE Reports and Utilities for UNIX (be carefull there are 8 parts). A Gilles, j'esper que je suis en France maintenant.pasc'est que j'ai habite en France dues ans. a bientot
