Question

继承我的SQL代码

SELECT system.name,  ceil(sum(((comp.price*1.3)/100)))*100-1 Computed_value, 'total_price' as type
FROM Computersystem system, component comp 
WHERE system.name='Corporal' AND
 ((comp.name = gpu) OR
 (comp.name = cpu) OR
 (comp.name = ram) OR
 (comp.name = mainboard) OR
 (comp.name = computercase))

GROUP BY system.name

UNION

SELECT system.name, min(currentStock) minCurrent, 'minCurrent' as type
FROM stock st, Computersystem system
WHERE system.name='Corporal' AND
 ((st.name = gpu) OR
 (st.name = cpu) OR
 (st.name = ram) OR
 (st.name = mainboard) OR
 (st.name = computercase))

 GROUP BY system.name;

哪个输出 table

现在想要获得一个包含以下行的表：

____Name_____Total Price______minCurrent____

我有办法做到这一点吗？

Answer 1

如果我有正确的问题，查询就像（在UNION之上）

<html>

<head>

    <meta charset="utf-8">
    <title>CS230 Assignment 3</title>
    <link rel="stylesheet" href="style1.css" type="text/css" media="all" />
    <script src="myjs.js" type="text/javascript"></script>

</head>

<body>

<h3>Diary:</h3>

<form action="insert.php" method="post">

<div id="table">

  <table>

      <tr>

        <th>Rational Response</th>
      </tr>

      <tr>

      </tr>

    </table>
