title: Mssql query exec returns error
body: <p>I'm connected to a sybase db through php's mssql driver.</p>
  
  <p>When I run this sql query:</p>
  
  <pre><code>$result = mssql_query("exec taxKM $rate, $var, $days, $discount, $distance, $inDate, $outDate, null", $cnx);
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>Warning: mssql_query(): message: ASA Error -188: Not enough values for host variables (severity 16)
  </code></pre>
  
  <p>I'm following the <code>taxKM</code> procedure specs.</p>
  
  <p>It seems there are missing values, isn't it?</p>
  
  <p>But if I'm following the specs, it has to do with wrong function specs?</p>
