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...

This is a general question regarding the use of view and stored
procedures. I'm fairly new to databases and SQL.
I've created a SQL database using an Access Data Project ("ADP") and
I'm satified with the table structure. I've moved on to building some
front ends for our users.
I'm running into situations where I want subreports to be built from
queries that are dependent on the values in other controls.
I've played with stored...

Hi,
I was curious, I am thinking of writing an application that loads a dataset
from a database that resides on a server. The question I have is this, if
multiple copies of the app will be running at once will there be problems
with data updates?
The reason I ask is I'm thinking like this:
User1 launches the app and the dataset is created from the data in the DB.

I'm creating a table that contains multiple records pulled out of the
database. I'm building the table myself and passing it to the page since the
table needs to be fairly customized (ie, a datagrid isn't going to work).
On this page, people can update a variet of records. On submit, I want to
then go in and update all of the records.
Normally, I'd make each form element include a runat: server and then
declare it in my codebhind so I...

does anyone experienced slowness when updating a dataset using
AcceptChanges?
when calling this code it takes many seconds to update the database
SqlDataAdapter1.Update(DsStudentCourse1)
DsStudentCourse1.AcceptChanges()
i'm also wondering because w/ out AcceptChanges the data is still save
into the database and it is now faster.

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.

In an application I am writing the user can define a series of
steps to be followed. I save them in a sql database using the
field "order" (a smallint) as the primary key.
(there are in the range of 20 steps)
On the admin page the steps are listed, in "order" order and the
user can create new steps and assign an order and all is well.
The problem may come in using a renumber function which should
take the steps in their current order...

Hi All!
I am with a situation where I am not getting the right updating to the
form's fields. The situation is the following one:
I have one combobox and one textbox. I am using the CurrentChanged event of
the BindingSource of the combobox to update the textbox. When selecting an
item in the combobox or when selecting a row in the grid, it is updating the
textbox correctly. The problem is when I apply a filter in the grid, and then...

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...
