下面说下调用
PHP;">
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
'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,$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
