Using DECLARE while creating a VIEW? - sql-server

Question

The literature says that the declare statement is not compatible with creating a View. How do I get around it?
My declare statement looks like:
DECLARE #risk_5 TABLE (Code VARCHAR(100));
INSERT INTO #risk_5 (Code) VALUES ('AA'),('BB'),('CC');
and is then used within a select statement:
SELECT
id,
CASE
WHEN a.[10_2_1_Country] IN (SELECT Code from #risk_5)
THEN '3'
END AS Risk_Country5
FROM x
The recommendation is to pack the declare into a CTE or a stored procedure.
With both these recommendations though, I do not understand how to connect the two? What am I missing?

If you need to use variable try to use stored procedures, if you write a select query in the stored procedure you can get the data too. And you can use declare inside.
I use this way in my solution e.g.
CREATE PROCEDURE [dbo].[GetLoadSiteMass]( #month INT,
#year int,
#storageId int,
#parent nvarchar(50),
#materialSourceId nvarchar(100),
#complexIds nvarchar(50))
AS
BEGIN
DECLARE #MonthPrev int
DECLARE #YearPrev int
SET #MonthPrev = CASE WHEN #Month = 1 THEN 12 ELSE #Month - 1 END
SET #YearPrev = CASE WHEN #Month = 1 THEN #Year - 1 ELSE #Year END
declare #WagonLoadSiteId int
set #WagonLoadSiteId = (select top 1 CarriageLoadSiteId from CarriageLoadSite where LoadSiteType = 2);
DECLARE #loadSide nvarchar(10), #result decimal(18,3)
SET #loadSide=cast( #storageId as nvarchar(50));
WITH CarriageLoadSiteTreeView (
[CarriageLoadSiteId],RootId,RootName,[Code], Name, ParentID, [LoadSiteType],IsDelete,
CodeSAP,DepartmentId, Capacity, MinLimit, MaxLimit, LoadSitePlaceTypeId) AS
