title: Whats the size of an SQL Int(N)?
body: <p>Simple question. I have tried searching on Google and after about 6 searches, I figured it would be faster here.</p>
  
  <p>How big is an int in SQL?</p>
  
  <pre><code>-- table creation statement.
  intcolumn INT(N) NOT NULL,
  -- more table creation statement.
  </code></pre>
  
  <p>How big is that <code>INT(N)</code> element? What's its range? Is it 2^N or is it N Bytes long? (2 ^ 8N)? Or even something else I have no idea about?</p>
