Hi,

I am trying to create a loader file that will allow me to append data to a table if the primary key does not exist and if the primary key exists in the table then to just update that row.

For example, append employee rows to the employee table from the loader file, else if the employee_number exists in the employee table then just update the employee details on the table with the employee details from the loader file.

Does anyone know how to do this?

Thanks for your help on this.

sql*loader WILL NOT do the update.
u have to use a trigger in the background.
or
load all records into another temp table.
from that temp table u can do whatever u want using sql
