title: SQL: Is it efficient to use tinyint instead of Integer if my max value is 255?
body: <p>Lets assume I want to save the count of datagrid rows which can be max. 24 because each row is 1 hour.</p>
  
  <p>To save the row index in the database a tinyint field would be totally enough. But back in my mind I remember slightly that databases are optimized for integers?!</p>
  
  <p>So is it worth to use tinyint?</p>
