How do i handle a null value for a date variable type. I am retrieving date
data from an access database and storing the records in an array for
processing. The array field has a date type and the db records are date type
with null permissible.
How should i handle the insertion of a null date record into the array? I
just cant leave it empty right?

Hi,
I am looking for opinions and alternatives for handling
null values in a data object which reads a record from a
database table.
This object will have properties which will be populated
from the DB table columns, standard enough. But what
about the instance where a column could be null.

I have a requirement that requires detection of rows deleted/updated by
other processes. My business objects call stored procedures to create,
read, update, delete data in a SQL Server 2000 data store. I've done
a fair amount of research on concurrency handling in newsgroups and
other resources. Below is what I've come up as a standard for
handling concurrency thru stored procedures. I am sharing with everyone
so I can get some comments...

I am trying to get my head around the concept of default, special or empty
values that appear in Access VBA, depending on data type. The Access Help
is not much (help), and the manual that I have is not much help here either.
Googling has given me a little help.
This is my current understanding -- I would appreciate any comments or
corrections...

to Variant...

void SomeFunction(DateTime date)
{
string text = date.ToString(); //This crashes if date is null
}
I am using a construct similar to above. I want to check if the date is null
or nor before processing it, but I am not able to figure out the syntax.

Is there a best way to handle various formats of dates for SQL server?.
The data comes in various input files with different date formats.
The ParseExact function looks like an "evil" and it doesn't seem to work for
some cases.

What's the prevailing wisdom & best-practice advice about when to let
a varchar (or any) column be NULL, and when to make it NOT NULL

Hi
Does anyone know of any good publically available set of standards for
managing dates when dealing with a database server (in my case SQL Server
2000 and c# VS2005).
At the moment, if I create a record in the database for say a job, the
invoicedOn date field will be left null within the data base, not being
assigned untill its actually invoiced.

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
