Question

I want to pull columns from two different tables next to each other.

I have php code as below :

<table>
 <tr>
<th>Date</th>
<th>Performance A </th>
<th>Performance B </th>
</tr>
$sql = "select date, Aperformance from table1 group by date";
$sql1 = "select date, Bperformance from table2 group by date";
$result = mssql_query($sql);
while ($column = mssql_fetch_array($result))

{
echo "<tr><td>".$column[0]."</td>";
echo "<td>".$column[1]."</td></tr>";
}

And this produces output as below :

 Date     | Performance A | Performance B
 01/05/12 | 40%           | 
 02/05/12 | 30%           |
 03/05/12 | 25%           |

Now I want to fill up the third column from query $sql1. I don’t want date column from $sql1, the second column Bperformance needs to put in here. How I can do that?

Answer 1

Assuming both queries return the same number of rows, you could simply do:

$result1 = mssql_query($sql);
$result2 = mssql_query($sql2);
while($column1 = mssql_fetch_array($result1)) {
    $column2 = mssql_fetch_array($result2);
    echo "<tr><td>$column1[0]</td><td>$column2[0]</td></tr>";
}

If the queries return different sized result sets, then you’ll have do some extra work.
