Question

so i have to tables that have a relation between them – relation type: one to many.
and i thought that the following query:

DELETE Orderstbl.*, ItemsInOrdertbl.*
FROM Orderstbl INNER JOIN ItemsInOrdertbl ON Orderstbl.OrderID = ItemsInOrdertbl.OrderId
WHERE (((Orderstbl.OrderID)=26));

will delete all the rows in both tables that contain the OrderID = 26
but to my surprise it filled the following error :

could not delete from specified tables

tried to find an answer on google , didnt help much thanks in advance 😀

Answer 1

You could also create a relationship that includes CASCADE DELETE, then when you delete from one it will delete from the other

from microsoft:

If you select the Cascade Delete Related Records check box when you
define a relationship, any time that you delete records in the primary
table, Microsoft Access automatically deletes related records in the
related table. For example, if you delete a customer record from the
Customers table, all the customer’s orders are automatically deleted
from the Orders table (this includes records in the Order Details
table related to the Orders records). When you delete records from a
form or datasheet with the Cascade Delete Related Records check box
selected, Microsoft Access warns you that related records may also be
deleted. However, when you delete records using a delete query,
Microsoft Access automatically deletes the records in related tables
without displaying a warning.

Using the CASCADE DELETE is a simple and clean way to make sure the correct records are removed from both tables.

Here is another article discussing CASCADE DELETE with MS-Access.
