“Must declare the table variable ”@name“” in stored procedure

Question

I have a procedure which returns the error:

Must declare the table variable \"@PropIDs\".

But it is followed with the message:

Answer 1

You can avoid using dynamic sql by creating a sql function that use a CTE (I found the code below many years ago on sqlservercentral - Amit Gaur) :

Change the body of your procs with something like this :

SELECT  p.WPRN AS ID,
p.Address  AS Address,
p.Address AS Street
  FROM [dbo].[Properties] AS p
WHERE 
   p.WPRN NOT IN ( SELECT item FROM dbo.strToTable(@NotNeededWPRNs, ','))

Below the sql code that transforms a string into a table :

CREATE FUNCTION [dbo].[strToTable] 
(
    @array varchar(max),
    @del char(1)
)
RETURNS 
@listTable TABLE 
(
    item int
)
AS
BEGIN

    WITH rep (item,list) AS
    (
        SELECT SUBSTRING(@array,1,CHARINDEX(@del,@array,1) - 1) as item,
        SUBSTRING(@array,CHARINDEX(@del,@array,1) + 1, LEN(@array)) + @del list

        UNION ALL

        SELECT SUBSTRING(list,1,CHARINDEX(@del,list,1) - 1) as item,
        SUBSTRING(list,CHARINDEX(@del,list,1) + 1, LEN(list)) list
        FROM rep
        WHERE LEN(rep.list) > 0
    )
    INSERT INTO @listTable
    SELECT item FROM rep

    RETURN 
END
