wordpress下sql调用同一数据库任意数据表内容并呈现

<div class="lianglanwenxin">
<header class="page-header"><h3 class="archive-title">网友最新提问</h3></header>
<?php
	$result = $wpdb->get_results("SELECT question_id,question_content FROM aws_question ORDER BY question_id desc LIMIT 0 , 10"); 
	foreach ($result as $topten) {  
		$question_id = $topten->question_id;  
		$question_content = $topten->question_content;   
		if ($question_id != 0) {
?>   
		<li><a href="https://qiexuxing.com/ask/?/question/<?php echo $question_id ?>" title="<?php echo $question_content ?>"><?php echo $question_content ?></a></li>  
<?php } } ?>
</div>

上述代码已经可以实现调用后列表显示
