PHP MySQL 3 tables Foreign Key Join data from 1 Table into the other 2
I have 3 tables Order, CheckoutStatus, and Statuses. There is a foreign key in Order and CheckoutStatus that references the Statuses table.
I need to join CheckoutStatus to Order linked by the PO column and I need to join Statuses to Order and to CheckoutStatus.
Here is the data in the tables
Order table
`PO` = 123456
foreign key `Statuses_id` = 2
CheckoutStatus
`PO` = 123456
foreign key `Statuses_id` = 0
Statuses
`id` 0 = Complete
`id` 2 = Completed
How do I write my SQL statement so that I can have a result like this.
Order
123456
Completed
CheckoutStatus
123456
Complete
This SQL statement I'm using does not display anything unless I remove one of the JOIN Statuses section of the statement.
SELECT * FROM `Order` JOIN `Statuses` ON Statuses.id = Order.Statuses_id JOIN `CheckoutStatus` ON Order.PO = CheckoutStatus.PO JOIN `Statuses` ON Statuses.id = CheckoutStatus.Statuses_id
php mysql join foreign-keys

You have two JOINs on table Statuses. You need to use table aliases to distinguish the two relationships :
SELECT
`Order`.PO,
s1.Status,
s2.Status
FROM
`Order`
JOIN `Statuses` s1 ON s1.id = Order.Statuses_id
JOIN `CheckoutStatus` ON Order.PO = CheckoutStatus.PO
JOIN `Statuses` s2 ON s2.id = CheckoutStatus.Statuses_id

besides using PHP to remove theStatuses_idfrom displaying in the output, is there something in the SQL statement I can add? Just want to display the PO number and the Status value of Complete and Completed as seen above in the question.

@Mike : query updated. You might have t change the name of the column that hold the status value (I assumed « Statuses.value »).

What is the reason to change the column name? The column names in theStatusestable areidandStatus.

@Mike... this information was not part of your original post so I had to assume. It is easy to change the query once you have the logic explained

this can get a little bit confusing you can split the query and on the basis of its fetched result, you can fetch further more
$sql4 = "SELECT * FROM `Order` JOIN `Statuses` ON Statuses.id =
Order.Statuses_id JOIN `CheckoutStatus` ON somthing"
$result4 = mysqli_query($conn, $sql4);
if (mysqli_num_rows($result4) > 0)
{
while($row3 = mysqli_fetch_assoc($result4))
{
$sql5='SELECT * FROM //the result of before joining other two '
}
}
