Question

I’d like to have something similar to a C++ integer constant that I could use across different stored T-SQL procedures:

SELECT * FROM SOMETABLE WHERE STATE = IsBeingProcessed;

with IsBeingProcessed being a named integer constant equal to say 4.

Is it possible in T-SQL?

Answer 1

You could create a User Defined Function in the master table which simply does the following:

CREATE FUNCTION dbo.IsBeingProcessed
(
)
RETURNS int
AS
BEGIN
    RETURN 4
END

Then this could be called like:

SELECT * FROM SOMETABLE WHERE STATE = dbo.IsBeingProcessed();
