Let's say I have an html form with 20 or 30 fields in it. The form
submits the fields via POST to a php page which updates a table in a
database with the $_POST vars. Which makes more sense?
1) simply UPDATING the values for all fields in the table, whether or
not any particular field has actually changed
2) running a second SELECT statement and comparing the $_POST vars to
the returned values, and only UPDATING those that have...

How important do you guys feel locking a database is while
updating/adding information? Do you do it with every app you make? Only
very high volume (traffic) apps? I'm trying to decide if my app needs it.

Hi guys,
I've been trying to implement an editable datagrid and i have been
succesful up to the point where i can update my datagrid row by row.
However what used to happen was that once i updated one row, all of
them were updated so i immediatelly figured out that i have to include
the id of every entry in the update statement. This is where the
problem is raised. My database is an Access database. The table i am
updating contains a Date...

Hello,
I have created an ASP.NET 2.0 application that utilized a Gridview Control
to display and update/delete data.
The problem I am having is that the gridview control is displaying the data
correctly but it is not updating or deleting the rows. What I did was, in
design view, added a gridview control and added an sqldatasource control. I
configured the data source to update and delete. In the gridview tasks I

The application we are developing uses MS Access 2003 database (with

We have noticed that during massive records updating the size of the
mdb file increases dramatically (from 3-4 to 200-300 Mb).
After compacting the file shrinks back to 3-4 Mb.
I have performed the following experiment. I created a test database

The table contains 10 thousands...

Hi
I'm hoping somebody can help me with the following problem that has occurred
to me.
Suppose I have two tables in an SQL Server database. Let's call these tables
A and B. Assume that A has two fields: a primary key and another holding a
string. In table B there are three fields: a primary key, a foreign key
(which links to the primary key in A) and other field holding a string.

Hi There
I'm not sure what exactly is going wrong here. I'm writing an application that retreives a table from a database (tbl_internalfaults) and updates it. (Actually, just the status column will need updating with 'CLOSED' where necessary.)
I have been trying to use the OLEDB command builder to build the statement to update the database however it is returning an error whenever I try to do this.
I already have a dataset full of data, 1...

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

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.
