title: In Oracle, is starting the SQL Query's WHERE clause with 1=1 useful?
body: <p>I'm working with a client that starts almost all of their WHERE clauses in Oracle with <code>1=1</code>. Forgive my ignorance, but isn't this a no-op? Are there any negative consequences of this usage?</p>
  
  <p>Here's a scrubbed example:</p>
  
  <pre><code>SELECT   gpz.zname
           ,gpp.pname
  FROM     table1 gpp INNER JOIN table2 gpz ON gpz.p_id = gpp.p_id
  WHERE    1=1
           AND gpp.active = 1
           AND gpz.active = 1
  </code></pre>
