title: In Oracle SQL how do we avoid having to prepend the schema name?
body: <p>My boss just sent me a query that he runs like the following :</p>
  
  <pre><code>  SELECT * 
    FROM po_requisition_lines_all prl, 
      po_requisition_headers_all prha, 
      po_req_distributions_all prda,   /* ETC */ 
  </code></pre>
  
  <p>But this query won't run for me unless I prepend hte schema before the table names :</p>
  
  <pre><code>  SELECT * 
    FROM po.po_requisition_lines_all prl, 
      apps.po_requisition_headers_all prha, 
      userx.po_req_distributions_all prda,   /* ETC */ 
  </code></pre>
  
  <p>Is there a way in Oracle to avoid having to prepend the schema before the table-name? </p>
