数据结构 MYSQL_RES MYSQL_DATA MYSQL_ROWS MYSQL_ROW MYSQL_FIELD 相关API mysql_store_result mysql_use_result mysql_fetch_row...(res); //mysql_fetch_row()毎执行一次,都从资源也就是结果集中依次取一条数据,...mysql_use_result()将结果保存在服务器,它必须通过对mysql_fetch_row()的调用,对每一行分别进行检索。...mysql_fetch_row MYSQL_ROW mysql_fetch_row(MYSQL_RES *result); 检索结果集的下一行,结束检索则返回null。...如果行中保存了调用mysql_fetch_row()返回的值,将按照row[0]到row[mysql_num_fields(result)-1],访问这些值的指针。
"; $result = @ mysql_query($sql, $conn) or die(mysql_error()); 3、两种查询函数array / row区别 格式:mysql_fetch_row...(result); 说明:mysql_fetch_row用来查询结果的一行保存至数组,该数组下标从0开始,每一个数组元素对应一个域。...格式:mysql_fetch_array(result); 说明:mysql_fetch_array和mysql_fetch_row功能基本相同,只不过它除了可以用从0开始的偏移量作索引,还可以用域名作索引
其中前一个函数只是初始化MYSQL_RES结构体,并不真正从服务器获取结果,后一个函数直接将全部数据读取到客户端*/ /*MYSQL_RES结构体可以通过以下函数获得数据*/ MYSQL_ROW mysql_fetch_row...mysql_use_result初始化检索,以便于后面一行一行的读取结果集,而它本身并没有从服务器读取任何数据,这种方式较之第一种速度更快且所需内存更少,但它会绑定服务器,阻止其他线程更新任何表,而且必须重复执行mysql_fetch_row...④调用mysql_fetch_row函数读取结果集数据。 上述两种方式最后都是重复调用mysql_fetch_row函数读取数据。...mysql_fetch_row函数的原型如下: MYSQL_ROW STDCALL mysql_fetch_row(MYSQL_RES *result); 参数释义: result就是mysql_store_result...<< endl; return 0; } // 重复读取行,并输出第一个字段的值,直到row为NULL while (row = mysql_fetch_row
dbdatabase,$db_connect); //执行MySQL语句 $result=mysql_query("SELECT id,name FROM user"); //提取数据 $row=mysql_fetch_row...mysql_connect()、mysql_select_db()等函数之前使用@(错误控制运算符),可以忽略掉系统产生的错误信息,然后我们用die()来自定义错误信息; ②提取数据的时候,除了上面的mysql_fetch_row...,常见的还有mysql_fetch_assoc和mysql_fetch_array,具体差别请查阅我的另一篇随笔《PHP中mysql_fetch_row()、mysql_fetch_assoc()和mysql_fetch_array
