There are two tables, parent and child table.
Foreign key field of the child table is not a required field. If the
data is submitted w/o a value into the foreign key field, what should
I make it as a default value? Should it be "null"?

I have several default constraints defined on a table. When I use the
Object Browser and expand the constraints for this table and
right-click and then select "Script Object to New Window As Create", a
create constraint statement for a different default constraint is
displayed than the one I just right-clicked on. For example, I click
on constraint "DF_C" and it shows me "DF_B".
The last time I encountered this, the solution was to...

Hi!
I'm wondering whether it's possible to set up the MS SQL function
ISNULL() as a default value to avoid NULL entries when importing data
into a table?!
For example, I want the column1, to have a 0 (zero) as default value,
when entering/importing data: isnull("column1",0)
I remember that it is possible to set up with a date function like

Hi
I am working on SQL SERVER 200 and I am trying to drop the default constraints set in few tables. I tired to follow the instructions given in MSDN for dropping a default:
1) Unbind the code
Exec sp_unbindefault 'tablename.columname'
When I try to run it, it gives me following this error message:
Server: Msg 15049, Level 11, State 1, Procedure sp_unbindefault, Line 98

Hi, all..
I'm creating a table with one column of type DATE, non nullable, with
a default of the current date.
The column syntax I'm using is "THIS_DATE_1 DATE NOT NULL DEFAULT
CURRENT DATE"
On LUW, the constraint compiles - I insert a row and the date value is
inserted with the correct default.

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,...
