下面说下调用
复制代码 代码如下:
function __autoload($mssqlutil)
{
require $mssqlutil.'.php';
}
$db = new mssqlutil($config['host'],$config['user'],$config['keys'],$config['base']);
主要说下带参数的存储过程调用
复制代码 代码如下:
$pname 存储过程名字
$parname 参数，参数形式很重要，是数组类型，对应关系为
array('@a'=>'a') @a 为存储过程里面的参数，a为要传递的值
$sqltyle 是存储过程参数的数据类型，是数组形式，也很重要
array(sqlchar,sqlvarchar),注意不要加单引号等，因为sqlvarchar是sql的一些常量
带参数存储过程
$db->executeprocedur($pname,$parname,$sqltyle);
无参数存储过程
$db->executeprocedurnopar($pname);
select * from t2 where t2.id in(select max(t2.id) from t1 join t2 on t1.id = t2.pid group by t1.id);
取每个分类的最新一条数据。此处做个记录。
t1为类别表，t2为主表
