下面说下调用

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

$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
