879. Can one load variable and fix length data records? (for DBA
Yes, look at the following control file examples. In the first we will load delimited data (variable length):
INTO TABLE load_delimited_data

If you need to load positional data (fixed length), look at the following control file example:
INTO TABLE load_positional_data
( data1 POSITION(1:5),
Can one skip header records load while loading?
Use the "SKIP n" keyword, where n = number of logical rows to skip. Look at this example:
INTO TABLE load_positional_data
( data1 POSITION(1:5),
