I am working with SQL Functions in DB2 for Windows/Linux/UNIX (V8.2.1) and
am having a problem setting input parameters for SQL Functions to null in
the Development Center.
My simple function, called Half, has a single integer input parameter and
divides this value by two to produce its result. It also tests the input
parameter to see if it is null; if it is null, it returns null. When I click
the Run button and try to use the SET TO...

I have an A97 table with a Yes/No field named
TowJob and a form bound to that table. The
TowJob control on the form is bound to the same
field. It is an option group with Yes and No bttns
valued at -1 and 0 respectively.
Unless I specifically set the table field's defaultvalue
to Null, the form comes up with an automatic value
of 0 in the control? The control has NO default
value property setting. Why is that?

My problem deals w/inserting nulls into database (SQL Svr 2K) for the
datetime fields activityDate and followUpDate where nulls are allowed.
>From the web form, the user can type in/select the activity or followup
date.
If, for this exercise, the followupdate textfield is empty, then when
the insert method of the class calls the InsertActivityLog stored
procedure, how can I get nulls inserted instead of 1/1/1900 because of

I have people telling me that I should set up objects for my tables, but I
am finding the Null problem makes that difficult.
It isn't a big problem if you are not updating the table, but if you are -
it is a real problem if you have Nullable fields. You can't always use a 0
or -1 to tell whether a field is null and dates are another problem. I
don't want to use some obscure date in the future for something like
"EndDate" or...

Hi
I am building a very simple data entry system with many forms and
input textboxes.
When I leave any part of the form empty (it allows nulls) it seems to
touch the field in the DB and the field is no longer NULL.
I have written a script to test for empty textboxes and insert DB.NULL
which is fine but when I want to load the data back into the form

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:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
