title: How to retrieve and increase fingerprint score in PL/SQL Developer?
body: <p>I am currently using PL/SQL Developer to query a database (Oracle 11g) to generate reports and aggregate data for use. The database collects vital statistics and other bio data such as  DOB, Place of Origin, nationality, parents details, etc. </p>
  
  <p>It also collects an individuals fingerprints and stores them as BLOBs. We use a Hongda S700 Four fingerprint scanner to collect the fingerprints. </p>
  
  <p>The fingerprints are then recorded into the database as BLOBs but also they are given a score; I believe they are called an 'Authentication Threshold Score' from Oracle. These scores indicate whether the fingerprint is qualified, unqualified, are a mismatch or whether the scores need to be increased to qualify the fingerprint. </p>
  
  <p>I am unsure as to what the code is to retrieve the data from the database and how to adjust the score to make the fingerprints qualified. What code (PL/SQL query) do I use to retrieve the fingerprint scores from the database and how do I adjust the scores?</p>
