I am having trouble setting up a query, it seems very simple but I cannot seem to determine if my database logic is incorrect or whether the query is incorrect.

There is one database with 3 tables, clients, orders and package.

The clients table has 3 fields, ID{primary key auto increment), email (varchar) and organisation (varchar).

The orders table has 10 fields, ID(from above), OderID (PRimary, autoincrement), WorkID (from package table), and othr fields relating to file paths, comments, feedback and date.

The package table has 2 fields, WorkID (primary Key autoincrem), name(varchar)

This is what I want the query to do:

The query must get all the rows from orders table where WorkID= 1 and must get the organisation field from clients based on each order. I am then going to order the rows by date.

Am I meant to be suing a join to get this query to work or is there a flaw in the database logic? Now yes I already know there is an error below as i am not comparing an ID from the two tables, but what I want to happen is for it to first get all the rows from orders where WorkID = 1 then add the clients.organisation field to each row found from WorkId = 1 where ID from clients corresponds to the ID assigned to that row.

Thanks for any help

$query =    "SELECT * 
             FROM orders INNER JOIN clients ON orders.ID = clients.ID
             WHERE WorkID = 1
             ORDER BY Date DESC";

WORKING NOW__________________________————————->>>>>>>>>>>>>>>>>>>>>>>>>>>

Ok guys ive got the query working but for some odd reason the number of rows being echoed in while loop i have set up is always 1 less than num_rows. Anyone have any idea as to why? This is my echo

<?php
include "../includes/connect.php";

$query =    "SELECT * 
             FROM orders INNER JOIN clients ON orders.ID = clients.ID
             WHERE WorkID = 1
             ORDER BY Date DESC";

$result = mysqli_query( $link , $query );

;}
?>

Also i have a question i regards to safety of a database. I have file paths stored in the database which get echoed according to each record fetch no user interaction all done via the server on page load, is it insecure to do so?

2nd question i have mutiple queries on the 1 page, what would be the best way to include each query where it is required? (Would putting it in a separate file and calling it before the echo be best?)

    You probably need something like that: 

    SELECT * 
FROM orders o
INNER JOIN clients c ON (c.id = o.id)
WHERE o.WorkID = 1
ORDER BY `Date` DESC

    Some side notices : you should change your column naming convention to something more descriptive (I’m talking about orders.id which is in your case is a reference to clients.id). Personally, I prefer to use id as a primary key in each table. Some people like to name it as [TABLE_NAME]_id, in your case order_id, client_id. Secondly, don’t use *; list all required fields. Also, I’d recommend to use a newer sql syntax for joining table (use JOIN keyword instead of listing all tables in FROM clause).
