title: Can I add a variable value in mySQL query to table?
body: <p>I have a table in my database in which I have three fields: <code>Field_1</code>, <code>Field_2</code>, <code>Field3</code>.</p>
  
  <p><code>Field_1</code> is auto-incremented integer.
  <code>Field_2</code> will be a string value provided by the user.
  <code>Field_3</code> should be a concatenation of <code>Field_2</code> and <code>Field_1</code>.</p>
  
  <p>Example: <code>(1, Dog, Dog1)</code> should be added to my table without me providing the <code>"Dog1"</code> input.</p>
  
  <p>How to do this? I want to make <code>Field_3</code> my primary key. I have tried to look for solutions online, but to no use. Sorry, if this is a very easy question. </p>
