title: Update Oracle table with values from CSV file
body: <p>I have a CSV file which contains an ID and several other columns. I also have a table in oracle where the ID identifies a row. How can I best replace the values that are in the table with the values in the CSV file while keeping the other columns the way they were before? </p>
  
  <p>This has to be done with tools available in oracle itself (i.e. PL/SQL or SQL scripts), I can not use a "real" scripting language (Python, ...) or a "real" program.</p>
  
  <p>Thanks,
  Thomas</p>
