select from two different table and display

Question

i have 2 different table named productlist and rsales

the ff data in productlist are

id|pcode|
1 |1220 |

and the ff data in rsales are

id|total|total_discount|
3 |500  |      50      |

my problem is that i want to select data from two different table which is productlist and rsales and display it horizontally. i tried everything but it display vertically. the result must be something like this

id|pcode|total|total_discount|
1 |1220 |500  |   50         |

this is my code so far but it only display data from single table

<?php
$con = mysql_connect("localhost","root","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("inventory", $con);



$result = mysql_query("SELECT * FROM productlist");

while($row = mysql_fetch_array($result))
  {
echo '<tr>';
echo '<td>'.$row['pcode'].'</td>';
echo '</tr>';
  }

mysql_close($con);
?>

Use join for two tables. So that you can get values in single row. — Saranya Sadhasivam, Aug 27 '13 at 10:59
Where is the link between `productlist` and `rsales`? Also, using `mysql_*` is now strongly discouraged. The library is deprecated and you should really be using MySQLi or PDO... — BenM, Aug 27 '13 at 10:59
You propably want to read this: [MySql Join](http://dev.mysql.com/doc/refman/5.0/en/join.html) — Jan Zeiseweis, Aug 27 '13 at 11:00
There is no relevant column between these tables. Based on which column you want to merge data between these tables. — DB_learner, Aug 27 '13 at 11:00
im just new to php and don't really know all. how can i apply what you are trying to say sir :) — user2656724, Aug 27 '13 at 11:03
there is no link between rsales and produclist i just wanna get data from these table. — user2656724, Aug 27 '13 at 11:04
hi there, @Mani is telling you that you need a common bit of info in each row to be able to link the data from different tables together. I linked a Q&A that I posted a while back in my answer below. You would do really well to have a good read of it. — Fluffeh, Aug 27 '13 at 11:08

Is the id difference between them offset by 2?If so,you can use Fluffeh answer like this:

select
 ffdata.pcode,
 rsales.total,
 rsales.total_discount
from
 ffdata
    join rsales
        on ffdata.id=rsales.id+2

This won't work as the tables have a different number of columns - nor would it really work anyhow as the data would come out on different rows - which is not what the question asked for. – Fluffeh Aug 27 '13 at 11:05
i think union can't be use for the kind of problem because there is no link or no common at all i just want to get data from two table . but i tried this code and error appears Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\wamp\www\eduards.org\admin\itemsales.php on line 136 – user2656724 Aug 27 '13 at 11:13

You need to use a join in your SQL so that the data comes out in a single row in the results and is matched on the correct fields.

I wrote a lengthy Q&A about it a while back for just this sort of question which you will really do well to read, but in short, your query should look something like this:

select
    ffdata.pcode,
    rsales.total,
    rsales.total_discount
from
    ffdata
        join rsales
            on ffdata.id=rsales.id

This is assuming that you have a common key on the two tables that links the records.

there is no link between rsales and produclist but you can try like this, you will get all fileds from both the tables using this

$result = mysql_query("SELECT * FROM productlist,rsales");

this is awesome code simple and direct. but what about if im going to sum the "total" value from rsale? any idea sir? i tried sum(total) but error appears :D – user2656724 Aug 27 '13 at 11:22
for that you need to define all the column names instead of (*) in your query with sum(total) – chirag ode Aug 27 '13 at 11:37
