title: Is an old Oracle syntax for outer joins (+) always equivalent to new syntax?
body: <p>I wonder if it's always possible to rewrite <code>LEFT JOIN</code> using old Oracle syntax<code>(+)</code>. In particular, I tried to express the following query using <code>(+)</code> </p>
  
  <pre><code>SELECT *
  FROM table_1 a
  LEFT JOIN table_2 b ON (b.table1_id = a.id AND b.other_field = 'value1')
  </code></pre>
  
  <p>without success. Is it possible at all?<br>
  Thank you.</p>
