You may be running an Oracle 10g Release 2 database server, but supporting some applications may have been written very early. Data tables created prior to Oracle 8i typically have a long data type to store large text. With the introduction of the large Object (LOB) data type, the long and long raw data types are discarded. If you are copying a data table that uses a Long data type, then using the CREATE table as SELECT syntax will not complete the t
