Here in PG, we have getting the proper date irrespective of the format as Oracle. But in the case to to_number the returned value is wrong. For example following query returns '340' on PG where as it returns '3450' on Oracle. select to_number('34,50','999,99') from dual; > But FWIW, a -1 from me for changing this. > Do you mean this is the expected behaviour then? > > Cheers, > BJ > -- Jeevan B Chalke EnterpriseDB Software India Private Limited, Pune Visit us at: www.enterprisedb.com --- If better is possible, then good is not enough
