mysql如何跳到指定记录 mysql_field_seek教程

<pre class="brush:php;toolbar:false"><strong>mysql_field_seek语法:</strong>

mysql_field_seek(data,field_offset)

参数:

data:必须 指的是mysql_query正确返回的数据集.

field_offset:指定位置.不写代码从0开始

看个mysql_feild_seek实例.

<pre class="brush:php;toolbar:false">$sql = "SELECT * from Person";

$result = mysql_query($sql,$con);

mysql_field_seek($result,3);

print_r(mysql_fetch_field($result));

mysql_close($con);

?>

输出结果.

stdClass Object<br>(<br>[name] => Age<br>[table] => Person<br>[def] =><br>[max_length] => 2<br>[not_null] => 0<br>[primary_key] => 0<br>[multiple_key] => 0<br>[unique_key] => 0<br>[numeric] => 1<br>[blob] => 0<br>[type] => int<br>[unsigned] => 0<br>[zerofill] => 0<br>)
