Trailing blanks are not loaded with nondelimited data types unless you specify PRESERVE BLANKS. If a data field is 9 characters long and contains the value DANIELbbb, where bbb is three blanks, then it is loaded into the Oracle database as "DANIEL" if declared as CHAR(9).
If you want the trailing blanks, then you could declare it as CHAR(9) TERMINATED BY ':', and add a colon to the data file so that the field is DANIELbbb:. This field is loaded as "DANIEL ", with the trailing blanks. You could also specify PRESERVE BLANKS without the TERMINATED BY clause and obtain the same results.
