--scenario

SQL

ALTER PROCEDURE [dbo].[APPROVED_KM]-- 20,0,15,4
(
@HUB_ID INT,
@Pageindex int,
@pageSize int,
@totalrows int output
)
AS
BEGIN

C#

; with cte as
       (

--all the codes are written inside the cte which i am not showing here
     
       )

--first query after cte

SQL

select
      @totalrows=count(rownum)
from cte

--second query after cte

SQL

select
     *
from 
    cte
order by address_id
OFFSET ((@Pageindex+1)-1)*@pageSize ROWS
FETCH NEXT @pageSize ROWS ONLY

---now when i executed the stored procedure ...."invalid object cte"

----------------------------------to avoid the problem i tried this-----------------------

SQL

select *
into #temp1
from cte


select
      @totalrows=count(rownum)
from
      #temp1
 
         print @totalrows
 
 
 
select
     *
from 
     #temp1
order by address_id
OFFSET ((@Pageindex+1)-1)*@pageSize ROWS
FETCH NEXT @pageSize ROWS ONLY

--is there any way to do without inserting into temporary table...is it possible to do with cte itself [execute the two query]

No, you can't use CTE outside the CTE. The only way is to use temporary table ;)

SQL

;WITH CTE AS
(
    --SELECT ...
)
INSERT INTO @tmp (DestField1, DestField2, ...)
SELECT (CteField1, CteField2, ...)
FROM CTE

SELECT @total = COUNT(*)
FROM @tmp

--and so on...
