Your description doesn't match with your table's column description. You said,you have number, varchar and date. So what is "file" that you want to load in this table? Do you mean that you are going to store an actual file in some column? If yes, you need to use Bfile as the data type. If not, tell us with a reproducible example and/or a better explanation that what you want to do ?
