PHP的结果集和ASP的记录集就只是叫法上的不同吗
我觉得PHP的结果集和ASP的记录集是一样的,它们都是内存中的一个虚表,都有一个指针指向当前记录。
就只在它们上面有些操作不同而已
PHP
每次输出记录后记录集指针可自动向下移动一条,结果集可自动关闭
ASP
需要手动使用rs.movenext将记录集指针移动到下一条,记录集必须手动关闭
ASP有BOF和EOF属性,PHP没有
不知我理解得对不对,希望大家能够补充或纠正哦
回复讨论(解决方案)
怎么没有人对这个帖子感兴趣吗
记录集 RecordSet 是 ADODB 的一个组件
结果集 result 是一个资源号
虽然两者都代表查询的结果,但他们是完全不同的两个东西
但是从实现的功能上看,它们基本是一样的吗
两个资源的类型不一样,但是实现的功能一样
php 的mysql_fetch_array,就是移动
参考如下代码
$result = mysql_query("SELECT id, name FROM mytable");
while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
printf ("ID: %s Name: %s", $row[0], $row[1]);
}
但是从实现的功能上看,它们基本是一样的吗
从实现的功能上看,基本一样。都是循环取结果集数据。
