Question

I have two tables, the first is a ‘users’ table which has a column called ‘store’ and I also have a table called ‘stores’ with columns ‘store number’ ‘store location’.

The column ‘store’ in the users table is a ‘store number’.

What I’m trying to do is create a HTML table that is something like

Sample data:

Store number: 34
Store location: London
Users: 34

Store Number | Store Location | Number of Users at this store|

So it would be something like select * from stores and for each create new row.

and for the number of users be something like sum * from users where ‘store’ = ‘store number’ from stores table.

I hope this makes sense,

Jack.

UPDATE:

This is correct:

$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>";

Tables:

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

Try this SQL:

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

and then do

echo $row['nbr_users'];

to print the number of users.
