I've been designing SQL server databases for a while and have always
assumed that primary keys and linking keys should be numbers rather
than textual fields to improve performance. As an example, if i were
to create a new table i would put in a surrogate primary key that
autoincrements.
I've recently been challenged on this and cannot seem to find any
evidence that would support the view that this is best practice.
Anybody have...

I used the Migration Workbench for Oracle 9.2 Client to migrate the
tables in an Access 2K back-end database to Oracle. (The Migration
Workbench is intended to automate the process of migrating tables from
Access to Oracle.) Following the migration, when I try to link the
Oracle table to the Access front-end using Oracle ODBC Driver, I have
to either select one or more fields in the Oracle table as key fields
or not have any key fields. ...

I have been using Access since office 4.3. I have just upgraded to Office
2003 and am having issues with creating updatable queries. If I link one
table to a selection query based on the same table, the resulting query is
not updatable. OR If I link 2 tables together that don't have a primary key
the result is not updatable.
I know I was able to do this in previous versions since I usually don't use
a primary key.
Thanks

Please help
I don't know if this is possible but what I would really like to do is
to use On Error Goto to capture the code that is being executed when
an error occurs.
Any help would be much appreciated.
Thanks in advance

I am trying to use Access as a front end for extracting information from
an Oracle database. I started using linked tables but I am getting a
very curious behaviour.
When I consult the linked table in access, the total number of records
is OK but some records appear several times and some records do not
appear at all. It seems as if access or the ODBC drivers returns several
times the same record and skips some of the records, curiosly...

Issue: I am inserting an Oracle record containing insert trigger via
Access 2002 using the code below. The issue is that the sequence from
the acSaveRecord is not reflected after the insert so the insert into
the second table section: ' Copy LOB entries now. fails on unique
index constraint (understandable because it has the orig rate_id).
The strange thing is that it works fine for new records that have

Hello!
I have a few tables in MS SQL Server 2000, where I have admin
permissions for these tables. I have created a blank database in MS
Access 2003, where I linked a table from MS SQL Server 2000. The
problems is that I have only read permissions on these tables in MS
Access 2003, while I have admin permissions in MS SQL Server 2000. Is it
possible to have the sime permission in both MS Access 2003 and MS SQL
Server 2000? Is it...

Hi All,
I've had Access 97, 2000 connections to the corporate Oracle database
for a few years now - but seldom use it. When I did use it years ago,
performance was not fast but the features were good enough. Now, the
version of Access is 2003 with Office SP1 applied, Windows XP against
Oracle 9.2. And attached tables are real slow - 5 mins to get to
datasheet view and data is incorrect - the same row is repeated several
times even in...

I’m using Access 2003 and am a novice to Access.
I am creating a form to facilitate data entry to seven tables. The main table (A) has four sub-tables that are related to the main table by one-to-one relationships. A fifth sub-table (B) has a one-to-many relationship to Table A and serves as a bridge to another table (C) also with a one-to-many relationship to that table. So far, I have used the sub-form wizard to create the main form and...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Dear forum friends,
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'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
