    SQL*Loader Sequential Data File Record Processing?

    User437258

      If I use the conventional path will SQL*Loader process a data file sequentially from top to bottom?  I have a file comprised of header and detail records with no value found in the detail records that can be used to relate to the header records.  The only option is to derive a header value via a sequence (nextval) and then populate the detail records with the same value pulled from the same sequence (currval).  But for this to work SQL*Loader must process the file in the exact same sequence that the data has been written to the data file.  I've read through the 11g Oracle® Database Utilities SQL*Loader sections looking for proof that this is what will happen but haven't found this information and I don't want to assume that SQL*Loader will always process the data file records sequentially.

       

      Thank you
