    调用

     

    function __autoload($MssqlUtil) { require $MssqlUtil.'.php'; } $db = new MssqlUtil($config['host'],$config['user'],$config['keys'],$config['base']);

     

     

    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);
