You need to look at ROW_NUMBER() to do this effectively.
Temp tables, cursors are to costly.
CREATE PROCEDURE myProc
@StartIndex INT
@MaxRecords INT
AS
SET @StartIndex = @StartIndex + 1
SELECT
first_name,
last_name,
middle_init
FROM
(SELECT
first_name,
last_name,
middle_init
ROW_NUMBER() OVER(ORDER BY last_name)
AS rownum
FROM
Users)
AS Users
WHERE
rownum between @StartIndex and (@StartIndex + @MaxRecords) -
1
Then we can use Dataset for best performance..
