从两个MYSql表中获取数据并显示为HTML表

Question

我有两个表，第一个是'users‘表，它有一个名为'store’的列，还有一个名为'store‘的表，列有'store number’和‘store location’。

users表中的“store”列是一个“store number”。

我要做的是创建一个HTML表，它类似于

示例数据：

店号: 34店铺位置:伦敦用户: 34

门店号|门店位置|该门店用户数

所以它应该类似于select * from stores和for each create new row。

对于用户数，类似于sum * from users where 'store‘=来自store表的'store number’。

我希望这是有意义的

更新：

这是正确的：

$result = mysql_query("SELECT * FROM stores", $con) or die(mysql_error());

echo "<table border='1'>";
echo "<tr> <th>Store Number</th> <th>Store Location</th> <th>Number of Users</th> </tr>";
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
    // Print out the contents of each row into a table
    echo "<tr><td>"; 
    echo $row['storenumber'];
    echo "</td><td>"; 
    echo $row['location'];
    echo "</td><td>"; 
    echo 'Amount of users here';
    echo "</td></tr>"; 
} 

echo "</table>";

表：

CREATE TABLE IF NOT EXISTS `stores` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `storenumber` int(11) NOT NULL,
  `location` varchar(40) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=4 ;

CREATE TABLE IF NOT EXISTS users (

  `id` int(50) NOT NULL AUTO_INCREMENT,
  `email` varchar(50) NOT NULL,
  `store` int(11) NOT NULL,
  `lastvisit` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=28 ;

Answer 1

试试下面的SQL：

SELECT storenumber, location, COUNT(users.store) as nbr_users FROM stores
LEFT JOIN users ON stores.storenumber = users.store
GROUP BY store.id

然后做

echo $row['nbr_users'];

打印用户数。

Answer 2

试试这个：

$result = mysql_query("SELECT * FROM stores", $con) or die(mysql_error());
echo "<table border='1'>";
echo "<tr> <th>Store Number</th> <th>Store Location</th> <th>Number of Users</th> </tr>";
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
    // gets the total amount of users
    $query = mysql_query("SELECT COUNT(*) AS total FROM users WHERE `store`='".$row['storenumber']."'") or die( mysql_error() );
    $r = mysql_fetch_array( $query );
    $total = $r['total'];
    unset($query, $r);

    // Print out the contents of each row into a table
    echo "<tr><td>"; 
    echo $row['storenumber'];
    echo "</td><td>"; 
    echo $row['location'];
    echo "</td><td>"; 
    echo $total;
    echo "</td></tr>"; 
} 

echo "</table>";

Answer 3

你可以试试这个-

$result = mysql_query("Select count(user_id) as CNT,storenumber,location from store Left join user ON user.store_number = store.store_number group by store.store_number", $con) or die(mysql_error());
$row = mysql_fetch_assoc($result );

echo "<table border='1'>";
echo "<tr> <th>Store Number</th> <th>Store Location</th> <th>Number of Users</th> </tr>";
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
    // Print out the contents of each row into a table
    echo "<tr><td>"; 
    echo $row['storenumber'];
    echo "</td><td>"; 
    echo $row['location'];
    echo "</td><td>"; 
    echo $row['CNT'];
    echo "</td></tr>"; 
} 

echo "</table>";

如果你能提供精确的表格结构，我就能更准确地组织它。
