In AccessXP in Access2000 mode ---
TblCustomer: CustomerID, CustomerName
TblOrder: OrderID, CustomerID, OrderDate
TblOrderDetail: OrderDetailID, OrderID, Detail
Appropriate relationships are established and referential integrity is enforced.
FrmCustomer/SFrmOrder is a form/subform based on the respective tables.

I have always taken it for granted that once RI is in place, no orphan
records can be created, and that RI can't be put in place while orphans
exist, but today I came across a situation where that is not true. I am
having a lot of trouble believing my eyes, so I would be very grateful for
anyone's feedback on similar issues.
The situation is the usual Invoice/Invoice Details one: the db has RI in
place on the relatioinship between...

Hi
First a simple question ...
I have a table "access_log" that has foreign keys "app_id" and
"app_user_id" that reference the "application_type" and "app_user"
tables. When I insert into "access_log", the referential integrity
triggers generate these queries:
SELECT 1 FROM ONLY "public"."application_type" x

Referential Integrity on one of our production tables seems to have been
lost. I am running Postgres 7.1.3 embedded within Red Hat
kernel-2.4.9-e.49.
Within that I have a table with referential integrity constraints which
no longer work.
I do not know how to disable referential integrity on a column in a table.
I do not know how to view what Postgres thinks my referential integrity

Is there a way to run an alter table statement that adds a constraint
for a foreign key, but does *not* check the existing data for
refrential integrity? I'm essentially looking for the equivalent to SQL
Server's NOCHECK flag.
I am able to create equivalent keys in the Relationships screen, as
long as the "Enforce referential integrity" box is left unchecked. But
when I try to create that relationship with an ALTER TABLE statement, I...

I've inadvertently placed this post in another similar newgroup, and I
apologise if you get it twice.
I'm building a database that consists of frontend and backend. Some
of the lookup tables need to reside in the frontend database. The
data in the lookup fields that relate to the backend tables will
never
change, but a descriptor for items in these fields will. I may need
to update the descriptors periodically, hence the need to keep...

Access2000, using a continuous form.
I’m getting a message that say “you cannot add or change a record
because a related record is required in table Employee”.
This occurs in all my combobox fields that have referential integrity
linked to another table. I do not have the field in the table set as
required, and I do not want to require the entry. If the record is
filled out completely and added to the table, you can go back to the...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
