===== Description =====
The function ''prepareSP()'' accesses an existing stored procedure. If the stored procedure is valid the function return a resource otherwise it returns false.

===== PrepareSp Correct Usage =====
''prepareSp'' should only be used with database drivers that support direct access to the procedures. It should not be passed an SQL statement that might access the procedure so, assuming a stored procedure ''PROC_LIST'' exists, 
the statement:
  $db->prepareSp('PROC_LIST') 
is correct, however 
   $db->prepareSp('CALL PROC_LIST')
is not.
-------------------------------------
===== Usage =====
<code php>
/*
 * Connection to SQL Server database
*/

/*
 * Accessing an existing stored procedure called kmnProc
 */
$stmt = $db->PrepareSP('kmnProc');
$val1 = 'ADMIN';
$par1 = 'users';
$db->InParameter($stmt,$val1,$par1);
$db->OutParameter($stmt,$ret,'RETVAL');
