Hi,
I'm making a sort of Customer and Orders database in MS Access 2003. My
problem is that I wish to update the table "tblTransaction" based on changes
made in the table "tblOrderDetails". There is no direct relationship between
these two tables. The "tblProducts" has a one-to-many relationship to "
tblOrderDetails" and "tblTransaction". I use the "tblTransaction" to count
number of items in stock for each product. I therefore wish...

I cannot get my OleDbDataAdapter to update my database
table from my local dataset table. The Knowledge Base
doesn't seem to help - see item 10 below.
I have a Microsoft Access 2000 database which indexes
computer magazine articles for personal reference.
I am developing a Visual Basic.NET program whose sole

Hello,
I have 2 tables with a relationship set up in the dataset with vb
..net. I add a new record to the parent table then edit an existing child
record to have the new parent ID. However when I do the update the changed
parentid in the child table fails to change. No error is given its just that
the change is not written to the Database.
When I step through the records for the child table the one I would expect
to be changed has a row...

I'm trying to update a SQL2000 database through a web form. Visual Basic.Net

The primary key field in the table is HospitalProviderNumber. It is an
NVarChar (10). Some of the Hospital Provider Numbers begin with zero

The table won't update with the WHERE clause. In my attempts to find what's

I have lots of tables to copy from one server to another. The new
tables have been created to match the old ones. I practiced with one
table. I created the select command (select * from tableA) and Visual
Basic .NET created an update command--very long as there are a lot of
fields.
Now there are more large tables to copy. Is there an easy way to have
Visual Basic create these update commands itself for the other tables

I will ask the question first then fumble thru trying to explain myself so i
dont waste too much of your time.
Question / Statement - Every mdb table needs a PrimaryKey ( or maybe an
index - i havnt tested the index yet ) so you
can use an .UPDATE( dataTable ) on the data adapter. Otherwise you will
get an exception error.
Is this statement true?

Hi,
I'm trying to build a database application in Visual Studio 2005 express Edition. Using Visual Basic, and a sample Access database, I created a new Windows Application, added a database, created a table, and then used the Configure Dataset wizard to create a tableset with the new table Table 1.
I dragged the tableset into the form, and Visual Studio 2005 created all the links, adapter, binging and dataset. But the problem is, the...

I'm fairly new to this so I'll try to be as clear as possible. I have a database that stores employee information and all job titles available. I have a main form that is based from a query and displays all job codes and job titles in the Job table. I also have a text box in the main form to keep track of the total number of positions available for this job title:
=DSum("","","=!")
Where JobVacancy is a table that contains JobCode, Department,...

Some of you may have seen my earlier thread “PasswordHash NULL problem”. I’ve started a new thread because investigation has shown that the problem is actually quite different than I previously stated. Also please note that this is unrelated to another of my previous threads, “dataAdapter.Update problem”, which incidentally has been resolved.
I’m learning SQL. I’m accessing database SQL2008 AdventureWorks, table Person.Contact, which has a...

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
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...
