I need some help to create a function that works the same way as VFP NVL function but only for integer or numeric fields.
I try it with integer fields and it doesnt work.
Any idea how to do it ?

TIA

create function NVL(@valor int, @Inicio int)
RETURNS int
AS
SELECT CASE
	WHEN @Valor IS NULL AND @Inicio IS NULL THEN NULL
	WHEN @Valor IS NULL AND @Inicio IS NOT NULL THEN @Inicio
	WHEN @Valor IS NOT NULL THEN @Valor
END
