I've written code that dynamically builds an sql query based on
various constraint possibilities.
The problem is the code would have been very complex had I not come up
with a dummy constraint as a kind of place holder in the statement.
To avoid complex logic that determines if there was another constraint
before any other constraint and hence the need to add, say, AND or
not, I came up with a dummy constraint so that every subsequent...

Hello,
In MSS 2k can Primary Key, Unique Constraints, Indexes and Foreign Keys be
disabled? If Indexes (PK's and UN Constraints) can be disabled what happens
if data is inserted while disable? Will the index be rebuilt when enabled?
Thanks,

I am working with an evaluation copy of SQL Server 2000 for the first
time; my DB experience lies with MS Access.
I have a simple table in SQL Server (tblCompany) that has a field
called "Ticker." When new company stock tickers (i.e., MSFT for
Microsoft) are entered into the field, I'd like them in all
caps--whether the user types msft, Msft, MsFt, etc. In Access, this
was easy--simply set the Format to ">" in table design view.

Greetings:
I have to do a one-off forceful change of some data in a database. I
need to disable some FK constraints, make the data change, and then
re-enable the constraints.
My process will be:
ALTER TABLE TABLE1 NOCHECK CONSTRAINT FK_TABLE1_TABLE2
UPDATE TABLE1 SET COLUMN1=2 WHERE COLUMN2='Problem row'

I have a Customer table. The table has two different CHECK constraints.
Then there is the Customer details dialog, which provides the user with
an UI for changing users. I have some UPDATE sql, which is called once
the user clicks the OK button on this dialog.

int rows = cmd.ExecuteNonQuery();

Hey, I've got what seems like a simple question, but I've been
wrestling around with it for way too long. I've got two fields in a
table named and . I don't want the user to be able to
enter a SPW (single piece weight) without entering the number of
pages. Since Access doesn't allow me to compare table fields in the
field validation rules (ie, ), I'm trying to do it
in the table validation and according to everything I've read it's...

Hi there,
I'm fairly new to database design, having only really worked with
existing tables etc in the past.
Simple question this really...........
In a users table, is it wise to have a ManagerID column that is

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...

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,...
