Question

I just get a problem executing my sql statement, This is the Northwind db.

    declare @PageIndex int
    declare @PageSize int
    declare @PageLowerBound int
    declare @PageUpperBound int
    declare @sql nvarchar(4000)

    select @PageIndex = 3
    select @PageSize = 5

    SET @PageLowerBound = @PageSize * @PageIndex
    SET @PageUpperBound = @PageLowerBound + @PageSize + 1
    with cts
    as
    (
    SELECT *
    FROM (SELECT ROW_NUMBER() OVER (ORDER BY OrderID) AS ROW,* FROM Orders)
    AS Orders  WHERE ROW >=@PageLowerBound AND Row<=@PageUpperBound
    )
   select @sql = @sql + 'select * from cte' 
    exec (@sql)

(Modified)
Just modify a little bit, I use select * from cte, I accidently pasted the wrong code. Sorry.
Actually, i am trying to append a where clause in @sql and execute it, but it throws a error message,saying “Incorrect syntax near the keyword ‘exec’.”
What did I do wrong?
Thank you

I’m guessing you are trying to make a standard CTE paging pattern (e.g. as described here) and make it dynamic for a pasted WHERE clause?

AFAIK you will also need to add the CTE into the sql string (exec or sp_executesql) in order to achieve this
