title: How to divide one column with another in MySQL?
body: <p>I have a table and there are four columns and I have numbers in two of those columns. I want to divide one column with another, so let's say in one column there is number 20 and in another column there is 4 and I want to divide those two, so I should get the number 5.</p>
  
  <p>How would I do that? Here is my schema:</p>

  <p>I want to divide <code>ocena</code> with <code>st_ocen</code>.</p>
  
  <p>Update: if I use this <code>string Query = "SELECT ocena / st_ocen FROM filmi.film WHERE film = Deadspeed 2013";</code> (since I am making this in C#) I get this error:</p>
  
  <blockquote>
    <p>Could not find specified column in results: ocena</p>
  </blockquote>
