title: .returning() is not supported by sqlite3 and will not have any effect
body: <p>Recently, I noticed the yellow warning in my console saying,</p>
  
  <blockquote>
    <p>.returning() is not supported by sqlite3 and will not have any effect.</p>
  </blockquote>
  
  <p>I'm using the <code>sqlite3</code> module with <code>knex.js</code>. It didn't put any effect on output but knowing what is it worths a lot. Here are my environment details. </p>
  
  <p><b>knex</b> v0.19.1<br>
  <b>sqlite3</b> v4.0.9<br>
  <b>Node</b> v10.16.9<br>
  <b>electron-builder</b> v21.2.0<br>
  <b>electron</b> v6.0.2</p>
