huge data load from flat file

    Question

  • Hi,

               I have to load around 3 GB of data daily from a flat file to DB.I have to load it incrementally. I can identify the changed data using 3 columns. If any of those column data is changed, i need to  delete it from DB, and insert that from flat file. There is not timestamp column. What can be the best approach to load the data?
