【问题描述】：
我的 php 中有两个选择查询。
$rr=mysql_query("SELECT * FROM tbl_sales_target WHERE rep = '502' AND DATE_FORMAT(date, '%Y-%m') = '2016-03'");
$r=mysql_query("SELECT SUM(tbl_sales.ton_ach/1000) AS tonSum, SUM(tbl_sales.val_ach/1000000) AS valSum FROM tbl_sales INNER JOIN tbl_mas_customer on tbl_sales.customer = tbl_mas_customer.customer WHERE rep = '502' AND DATE_FORMAT(date, '%Y-%m') = '2016-03'");
我想将每个查询输出合并到一个 Json 中。 这是我的两个查询的 Json 输出
{"feed":[{"rep":"502","date":"2016-03-01","val_tar":"64.91","ton_tar":"84.59","col_tar":"69.92"}]}{"feed":[{"tonSum":"45.201940","valSum":"33.150250"}]}
我想要的是这样的。
{"feed":[{"rep":"502","date":"2016-03-01","val_tar":"64.91","ton_tar":"84.59","col_tar":"69.92","tonSum":"45.201940","valSum":"33.150250"}]}
这是我的 php 脚本。
$r=mysql_query("select sum(tbl_sales.ton_ach/1000) as tonSum, sum(tbl_sales.val_ach/1000000) as valSum from tbl_sales inner join tbl_mas_customer on tbl_sales.customer = tbl_mas_customer.customer where rep = '502' and DATE_FORMAT(date, '%Y-%m') = '2016-03'");
$rr=mysql_query("select * from tbl_sales_target where rep = '502' and DATE_FORMAT(date, '%Y-%m') = '2016-03'");
$result = array();
$resultt = array();
while($row=mysql_fetch_array($rr)){
array_push($result,
array('rep'=>$row[0], 'date'=>$row[1],'val_tar'=>$row[2],'ton_tar'=>$row[3],'col_tar'=>$row[4]));}
while($row=mysql_fetch_array($r)){
array_push($resultt,
array('tonSum'=>$row[0],
'valSum'=>$row[1]));}
$json['feed']= $result;
echo json_encode($json);
$jsonn['feed']= $resultt;
echo json_encode($jsonn);

已编辑
$r=mysql_query("SELECT tbl_sales_target.*,
SUM(tbl_sales.ton_ach/1000) AS tonSum,
SUM(tbl_sales.val_ach/1000000) AS valSum

enter code here
输出
{"feed":[{"rep":"502","date":"2016-03-01","val_tar":"64.91","ton_tar":"84.59","col_tar":"69.92"},{"tonSum":"45.201940","valSum":"33.150250"}]}
我想要什么
{"feed":[{"rep":"502","date":"2016-03-01","val_tar":"64.91","ton_tar":"84.59","col_tar":"69.92","tonSum":"45.201940","valSum":"33.150250"}]}

【问题讨论】：
-
能否请您发布示例。
tbl_sales和tbl_mas_customer的数据。您需要在第一个查询中使用连接 -
你为什么不只是简单地选择具有第二个查询的列？而不是 2 个查询。
-
它没有用。我尝试对三个表使用内部联接。它没有用.. [我的桌子][1] [1]：i.stack.imgur.com/zJTB6.jpg
-
为什么
table_sales_target没有关系？foreign key和primary key的关系在哪里？ -
table_sales_target 没有主键。值重复
