title: sql syntax for update using php oci
body: <p>Any thoughts on why the query works in SQLDeveloper but in php it doesn't?</p>
  
  <pre><code>$update = " update TABLENAME SET LASTMOD=current_timestamp WHERE TABLE_NAME=$table ";
  $stmt = oci_parse($conn, $update);
  oci_execute($stmt, OCI_DEFAULT);
  oci_free_statement($stmt);
  </code></pre>
