title: List available datatypes in MySQL
body: <p>How can I programmatically list all available datatypes in MySQL?</p>
  
  <p>Like <code>SELECT * FROM sys.types in MS-SQL.</code></p>
  
  <p>I believe it is not possible, but anybody knows for sure ?
  <br /><br />
  <strong>Note</strong>: I do <strong>not</strong> need only the types used as in </p>
  
  <pre><code>SELECT DISTINCT data_type FROM information_schema.columns
  </code></pre>
