title: Beginner to sqlite - Can't create a database
body: <p>So I'm very new to this and I'm trying to create a database using sqlite (with the instructions in their documentation). I get this error after the first line of code. Does anyone know what's going on?</p>
  
  <p>I'm using terminal on OS X Lion.</p>
  
  <pre><code>$ sqlite3 ex1.db
  SQLite version 3.7.5
  Enter ".help" for instructions
  Enter SQL statements terminated with a ";"
  sqlite&gt; create table tb11(one varchar(10), two smallint);
  Error: unable to open database "ex1.db": unable to open database file
  </code></pre>
  
  <p>Thanks in advance!</p>
