How can empty fields be detected. - SELECT * FROM products WHERE
-
description IS EMPTY
The field may be NULL
or just empty and I suppose even space characters.

Thanks Delerna
I figured as much, I do something similar in MySql.
Although I once had a regex that achieved this.
But it may need to be RTRIM(LTRIM(des cription))=''

also... -
WHERE isnull(rtrim(ltrim(description)),'') = ''

Recognized Expert Top Contributor - WHERE isnull(rtrim(ltrim(description)),'') = ''
I like that ck9663, although I can't quite see how it works.
It looks like a COALESCE should be there

We need an additional function in the String class. We need the ability
to suppress empty fields, so that we can more effectively parse. Right
now, multiple whitespace characters create multiple empty strings in the
resulting string array.

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
