搞不懂了，数据库数据查询问题。
搞不懂了，数据库数据查询问题。
数据库设计如下
 l1 l2 l3 l4 l5 l6 dqs jqs zqs firstarea secondarea thirdarea ac
"1","1","2","3","4","5","6","21","0","3","4","6","0","0","0"
"2","1","2","3","4","5","7","22","0","4","5","6","0","0","1"
"3","1","2","3","4","6","7","23","0","3","4","6","0","0","1"
"4","1","2","3","5","6","7","24","0","4","5","6","0","0","1"
"5","1","2","4","5","6","7","25","0","3","4","6","0","0","1"
"6","1","3","4","5","6","7","26","0","4","4","6","0","0","1"
"7","2","3","4","5","6","7","27","0","3","4","6","0","0","0"
"8","1","2","3","4","5","8","23","0","3","4","6","0","0","2"
"9","1","2","3","4","6","8","24","0","2","3","6","0","0","2"
"10","1","2","3","5","6","8","25","0","3","4","6","0","0","2"
"11","1","2","4","5","6","8","26","0","2","3","6","0","0","2"
"12","1","3","4","5","6","8","27","0","3","3","6","0","0","1"

想根据已有条件选出来l1,l2,l3,l4,l5,l6的号码，设计了一张大表，包涵全部数据信息。。。
如，根据顾客利用表单提交的dqs,jqs,zqs,firstarea,secondarea,thirdarea等信息的值，挑选出l1到l6的号码都有什么。请问查询语句如何设计，还有表单的输入信息，如何传递给查询语句进行查询？

PHP code

我的想法

如下条件要同时满足   
<form method=post action="query_action.php">
<p>大号数：
<input type="text" name="dqs"></p>
<p>奇数：
<input type="text" name="jqs"></p>
<p>质数：
<input type="text" name="zqs"></p>
<p>第一部分：
<input type="text" name="firstarea"></p>
<p>第二部分：
<input type="text" name="secondarea"></p>
<p>第三部分：
<input type="text" name="thirdarea"></p>
<p><input type="submit" value="查"></p>
</form>

<?php  //query_action.php
$dqs=$_post['dqs'];
$jqs=$_post['jqs'];
$zqs=$_post['zqs'];
$firstarea=$_post['firstarea'];
$secondarea=$_post['secondarea'];
$thirdarea=$_post['thirdarea'];

$db=new mysqli('localhost','admin','admin','ssq') ;  
//mysql_connect("localhost
