Php SQL查询,我需要获取一些值

Php SQL查询,我需要获取一些值,php,mysql,Php,Mysql,我有两张桌子,一张和二张 表1包含以下字段: id atype adesc aid id aid adesc value_1 value_2 表2包含以下字段: id atype adesc aid id aid adesc value_1 value_2 $query1 = mysql_query("Select DISTINCT atype from table1"); while($row = mysql_fetch_array($query1)){ $atype = $

我有两张桌子,一张和二张

表1包含以下字段:

id
atype
adesc
aid
id
aid
adesc
value_1
value_2
表2包含以下字段:

id
atype
adesc
aid
id
aid
adesc
value_1
value_2

$query1 = mysql_query("Select DISTINCT atype from table1");
while($row = mysql_fetch_array($query1)){
    $atype = $row['atype'];
    $query2 = mysql_query("Select adesc from table1 where atype='$atype' and aid IN (Select aid from table2 ) order by id asc");
    while($row2 = mysql_fetch_array($query2)){
        // i know query2 can only get adesc, so i need value_1 and value_2 in this
        echo $row2['adesc'] .'>> '. (this should be value1 from table2) .'>> '. (this should be value2 from table2);
    }
}

我还想得到
值_1
值_2
。任何帮助都将不胜感激




编辑:
表1值在我的数据库中(分别为atype、aid和adesc):

表2中的值(分别为aid、adesc、val1和val2):

我真正想表达的是:

type1
      (sum)value_1 (sum)value_2
type2 
      (sum)value_1 (sum)value_2
type3
      (sum)value_1 (sum)value_2
type4
      (sum)value_1 (sum)value_2

此SQL查询应生成所需的结果:

select adesc, 
       value_1, 
       value_2 

from   table1 

where  atype='$atype' and 
       aid IN (Select aid from table2 ) 

order by id asc

在SQL中使用一个简单的innerjoin,而不是两个选择:

select table1.adesc,atable2.value1 from table1,table2 where table2.adesc=table1.adesc and table1.aid=table2.aid order by table1.aid asc

upd:


$sql=就这样-Connor基于内部连接编写了整个代码。“table2.adesc=table1.adesc”源代码中未指定此条件code@int2000很明显,他们并没有考虑我该如何付款。请查看我的编辑信息以了解详细信息。显然,他们没有考虑我应该如何显示它。请查看我的编辑信息以了解详细信息。thx对于您的更新伙伴,我现在少了1个无忧:D thx很多。。谢谢我真的希望,
$atype
永远不会是
“Jade的类型”
select table1.adesc,atable2.value1 from table1,table2 where table1.aid=table2.aid order by table1.aid asc
    $query2 = mysql_query("Select t1.adesc, t2.value_1, t2.value_2 from table1 as t1, table2 as t2 where t1.atype='$atype' and t1.aid = t2.aid order by t1.id asc");

    while($row2 = mysql_fetch_array($query2)){
        // i know query2 can only get adesc, so i need value_1 and value_2 in this
        echo $row2['adesc'] .'>> '. $row2['value_1'] .'>> '. $row2['value_2'];
