title: Parse error when inserting a row
body: <p>I have a problem when inserting a row into my database, 
  it adds the row but after that sends this parse error.
  From frontend I am sending an JSON POST request, and in backend
  I've installed mysql from npm and used it to connect to database.</p>
  
  <p>The problem is with first\ in query how can I disable that or anything 
  else that I can do? It works if I remove them from query.<br>
  I've tried with INSERT INTO VALUES and it doesn't works either.</p>
  
  <p>mysql debug:</p>
