Hi
I am loading data from the flat file in to a table using sqlloader. I am appending to the already existing data.
Can I compare the data in the flat file with the already existing data in the table while loading??

For example the data from position(10:20) corrosponds to an id number. So whenever this id number is already in the table it manipulates the field inthe flat file from position(30:34)(increases that field by 1) and then loads in to the table. If the id number is not there in the table it just loads the data whatever in the flat file.

So how can I compare the data from the flat file with already existing data in the table? What condition should I add in the control file?

Thanks,
Sri

You cannot compare with sql*loader.
You can load the flat file as is into an staging table.
then use sql means to compare the staging table and original table and load only the records you want.
