自己网站折腾中，需要用到查询另外一个数据库信息并且输出数据关联起来，这样更有利于网站SEO，怎么做呢？以下实例：

首先按照以下文章设置数据库权限：
 

[e:loop={"select * from sql_feisu_gushi.{$dbtbpre}ecms_mingju where classid=3 order by rand() desc limit 20",10,24,1}]
<?php
$zz=$empire->fetch1("select * from sql_feisu_gushi.{$dbtbpre}ecms_sinfo where title='$bqr[writer]' limit 1"); 
$sw=$empire->fetch1("select * from sql_feisu_gushi.{$dbtbpre}ecms_article where title='$bqr[gsfrom]' and writer='$bqr[writer]' limit 1");
$btfl=$empire->fetch1("select * from sql_feisu_gushi.{$dbtbpre}enewsinfotype where typeid='$zz[ttid]'");
$num=$empire->gettotal("select count(*) as total from sql_feisu_gushi.{$dbtbpre}ecms_article where writer='$bqr[writer]'");
$lmurl=$zz[titleurl];
$lmurl=str_replace('.html','/',$lmurl);  //替换小列表链接
?>
<li><a href="<?=$bqr[titleurl]?>" class="biaoti" title="<?=$bqr[title]?> "><?=$bqr[title]?> </a>
<div>出自<a class="gs-service-dynsty" href="/gushi/<?=$btfl[tpath]?>/"><?=$btfl[tname]?></a>：<a class="gs-service-author" href="<?=$zz[titleurl]?>"><?=$bqr[writer]?></a>的《 <a class="gs-service-author" href="<?=$sw[titleurl]?>"><?=$bqr[gsfrom]?></a> 》</div>

</li>
