title: Reading data from excel to query database
body: <p>I am not exactly sure what the best approach here is.  I am a novice programmer, trying to learn Java and I have a task I would like to complete.    I have data in a Excel file.   The Excel file has multiple columns.   I need to take a the value from a particular column, use it to query a database.  If the query returns null then add a value to a column, or mark it some how.  If the the query returns a value then do nothing.   Move to the next line.  </p>
  
  <p>anyone want to throw a noob a bone?</p>
