title: SQL loader to load data into specific column of a table
body: <p>Recently started working on SQL Loader, enjoying the way it works.
  We are stuck with a problem where we have to load all the columns in csv format say (10 columns in excel)but the destination table contains around 15 fields. 
  filler works when you want you skip columns in source file but unsure what to do here.
  using is staging table helps but is there any alternative?</p>
  
  <p>Any help is really appreciated.
  thanks.</p>
