title: Difference between INT PRIMARY KEY and INTEGER PRIMARY KEY SQLite
body: <p>Is there any difference between  <code>INT PRIMARY KEY</code> and <code>INTEGER PRIMARY KEY</code>  when defining a schema for a table? 
  When int primary key is used, I got <code>sqlite_autoindex</code> <em>thing</em> generated; 
  when  integer primary key , I got <code>sqlite_sequence</code> table generated. 
  what's the difference? what side effects can have the first and second variants?</p>
