php 呼叫sybase 的sp

sp:
CREATE PROCEDURE dbo.sp_u_test_test
@mult1 int, @mult2 int, @result int output
AS
BEGIN
select @result = @mult1 * @mult2
END

php:
$sql="declare @guess int
select @guess = 0
execute databse..sp_u_test_test 5, 6,
@result = @guess output";

$query=sybase_query($sql);

echo sybase_result($query,0,0);
==>30
