title: SQLite Query to Insert a record If not exists
body: <p>I want to insert a record into a sqlite table if its actually not inserted.</p>
  
  <p>Let's say it has three fields pk, name, address</p>
  
  <p>I want to INSERT new record with name if that name not added preveously.</p>
  
  <p>Can we do with this in a single Query. Seems like its slightly different from SQL Queries sometimes. </p>
