示例 #1 cubrid_unbuffered_query() example
<?php
$link = cubrid_connect("localhost", 30000, "demodb", "dba", "");
if (!$link)
{
die('Could not connect.');
}
$query = "select * from code";
$result = cubrid_unbuffered_query($query, $link);
while ($row = cubrid_fetch($result))
{
var_dump($row);
}
cubrid_close_request($result);
cubrid_disconnect($link);
?>
注意:
The benefits of cubrid_unbuffered_query() come at a cost: you cannot use cubrid_num_rows() and cubrid_data_seek() on a result set returned from cubrid_unbuffered_query().
