pdo\_query() - 执行一条非查询语句 ### 说明 ~~~ int | boolean pdo_query($sql, $params = array()) ~~~ ### 参数 * **$params**指定SQL语句中绑定参数的值，参数占位与 pdo\_fetch 一致 ### 示例 ~~~ //更uid等于2的用户的用户名 $result = pdo_query("UPDATE ".tablename('users')." SET username = :username, age = :age WHERE uid = :uid", array(':username' => 'mizhou2', ':age' => 18, ':uid' => 2)); //删除用户名为mizhou2的记录 $result = pdo_query("DELETE FROM ".tablename('users')." WHERE uid = :uid", array(':uid' => 2)); if (!empty($result)) { message('删除成功'); } ~~~
