title: Oracle SQL Syntax: Inner Join
body: <p>I don't have access to an Oracle Database right now, so I'm posting my question here:</p>
  
  <p>Is the following statement valid Oracle SQL Syntax?</p>
  
  <pre><code>SELECT a1
  FROM t1 INNER JOIN t2
  </code></pre>
  
  <p>I'm particularly wondering whether we need to specify a join attribute for the inner join.</p>
  
  <p>Best,
  Will</p>
