Hello, Does anybody know if this "very useful" feature will be "exposed" to us mortals in the next version (11g) ? Anybody using it in "production" ? It is used internally in some Oracle products and it does actually work but it is "officially" not documented... It is available in other RDBMS systems (DB2, SQL Server) but not on Oracle which I find "odd"... Thanks! Nilo Segura Oracle Support - IT/DEs CERN - Geneva Switzerland
