Fetch Values of same name item, without repeating item name? - php

Question

I am making a page of my products, in which i have many products with having same names but different specifications and prices.
PHP code:
<code>
$SelectList = "SELECT a.p_id, a.dis,a.name,b.p_id,b.rate
FROM tst1 a
INNER JOIN max b
ON a.p_id = b.p_id GROUP BY name";
$Query = mysql_query($SelectList) or die(mysql_error());
$Num_rows = mysql_num_rows($Query);
$array = array();
while($Data=mysql_fetch_assoc($Query))
{
$array['name'][] = $Data['name'];
$array['rate'][] = $Data['rate'];
$array['dis'][] = $Data['dis'];
}
</code>
<code>
<table border="1">
<thead>
<th>Description</th>
<th>Unit</th>
<th>Qty</th>
<th>Rate</th>
</thead>
<tr>
<td colspan="0">BUTTERFLY VALVES</td>
</tr>
<tr>
<td>65 mm</td>
<td>Nos</td>
<td>15</td>
<td>40%</td>
</tr>
<tr>
<td colspan="0">BUTTERFLY VALVES</td>
</tr>
<tr>
<td>85 mm</td>
<td>Nos</td>
<td>45</td>
<td>40%</td>
</tr>
<tr>
<td colspan="0">WASHER VALVES</td>
</tr>
<tr>
<td>32 mm</td>
<td>Nos</td>
<td>95</td>
<td>30%</td>
</tr>
</table>
</code>
So what i want is, if product name is same so just fetch only "name" once, and its "unit, qty & rates" all of them.
<code>
<table style="position:relative; top:10px; bottom:10px; left:200px" border="1">
<thead>
<th>Description</th>
<th>Unit</th>
<th>Qty</th>
<th>Rate</th>
</thead>
<tr>
<td colspan="0">BUTTERFLY VALVES</td>
</tr>
<tr>
<td>65 mm</td>
<td>Nos</td>
<td>15</td>
<td>40%</td>
<td>85 mm</td>
<td>Nos</td>
<td>45</td>
<td>40%</td>
</tr>
<tr>
<td colspan="0">WASHER VALVES</td>
</tr>
<tr>
<td>32 mm</td>
<td>Nos</td>
<td>95</td>
<td>30%</td>
</tr>
</table>
</code>

Answer 1

check this subquery.. this will help you out..
$qry = mysqli_query("select * from product group by name");
while($row = mysqli_fetch_array($qry))
{
echo "<tr><td colspan="0">'".$row['name']."'</td></tr>";
$qry2 = mysqli_query("select * from product where name = '".$row['name']."'");
echo "<tr>";
while($row2 = mysqli_fetch_array($qry2))
{
echo "<td>'".$row2['mm']."'</td><td>'".$row2['nos']."'</td><td>'".$row2['qty']."'</td><td>'".$row2['percentage']."'</td>";
}
echo "</tr>";
}

Answer 2

You may use either distinct or group by operator in your SQL to do so.
Usage of distinct looks like this:
SELECT DISTINCT column_name,column_name
FROM table_name;
You may take a look at this example of distinct.
Usage of group by looks like this:
SELECT column_name, aggregate_function(column_name)
FROM table_name
WHERE column_name operator value
GROUP BY column_name;
Here is an example of group by.
I hope this helps.
