I have a book cataloge where I have an author id linked up to the book.
However, I'm finding that some books have mulitple authors, and I'm
wondering if there is a way to add more than one id to the author id
field. Or do I have to have many author id fields? Any way around that?
Thanks,
Bill

Would it be OK to use varchar(5) instead of char(5) as the first field of a
composite clustered index?
My gut tells me that varchar would be a bad idea, but I am not finding much
information on this topic on this when I Google it.
Currently the field is Char(4), and there is a need to increase it to hold 5
characters.
TIA

One table I manage has a clustered index, and it includes some
varchar columns. When it is initially created, all the columns
in the clustered index are populated, and then some of the longer
varchars are populated through update queries. If the varchar
columns are stored outside the clustered structure, then it would
make sense to create the clustered index before populating the
varchar columns. Otherwise it would make sense to wait,...

Can I set the Format property in a date/time field in code?
Can I set the Input Mask in a date/time field in code?
Can I set the Format of a Yes/No field to Checkbox in code?
I am working on a remote update of tables and fields and can't find enough
information on these things.
Also, how do you index a field in code?

I've been doing a bit of reading and have read in quite a few places
that an identity column is a good clustered index and that all or at
least most tables should have a clustered index. The tool I used to
generate tables made them all with non clustered indexes so I would
like to drop all of them and generate clustered indexes. So my
questions is a) good idea? and b) how? There are foreign key references
to most of them so those would...

Hi
I thought that given a table with an index, primary key and
clustered index any non clustered index look ups would go via the
clustered index and the primary key is irrelevant?
(sql server 2000). A colleague has said that the primary key should be
the clustered index
because all index lookups will go via the primary key.
Is this right? I thought the primary key was nothing more than a
constraint on what data can be entered into the...

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...

Overview:
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,...
