ORA-00922
        missing or invalid option
        
        
        Cause
        An invalid option was specified in defining a column or storage clause. The valid option in specifying a column was NOT NULL to specify that the column cannot contain any NULL values. Only constraints may follow the datatype. Specifying a maximum length on a DATE or LONG datatype also causes this error.
        Action
        Correct the syntax. Remove the erroneous option or length specification from the column or storage specification.
