I wonder why it's called a 'variable'.

Hello!

I think that since we are in 2023 and the text references 2022, it will be better to use a variable in the text to read the year from the system and avoid the confusion.

Enjoying the content of SSC since a while...

Lol, not sure that's the place for a variable. Silly me still in the habit of typing 2022.

It's fixed.

A useful feature would be declaration of user defined global constants at the server or database level.

For example:

DECLARE CONST @@PI NUMERIC(12,10) = 3.1415926535;
DECLARE CONST @@StatusInProcess TINYINT = 2;
DECLARE CONST @@StatusDelivered TINYINT = 3;
DECLARE CONST @@GB BIGINT = 1073741824;

You can kind of do this using scalar functions, but that can potentially have adverse effects on query execution plans.
