cmd.commandText :="select top 10 from table "
ada.fill(dt)
for each(datarow dtr in dt.rows)

Microsoft introduced ROW_NUMBER() in SQL Server 2005 to help with paging…

SELECT * FROM (     
  SELECT          
  ROW_NUMBER() OVER (ORDER BY City) AS row, *  
  FROM Cities  
) AS a WHERE row BETWEEN 1 AND 10

Use a variable for 1 and 10 to dynamically get the next set.

create proc dbo.whatever_select_paging
  @int page
as

SELECT * FROM (     
  SELECT          
  ROW_NUMBER() OVER (ORDER BY City) AS row, *  
  FROM Cities  
) AS a WHERE row BETWEEN ((@page-1) * 10) +1 AND (@page * 10)-1
