This might help you Use the LIMIT clause in your SQL queries.
What you want is called pagination - each batch of records is considered a page. You have to somehow (through session, or in the link the user clicks) have to hold account for your current page and request for the next like:
SELECT .... LIMIT (page_no * batchsize), batchsize

it should still fix some issue Rid is correct. This question appears to be a duplicate of Finding the next available id in MySQL

it helps some times So I found this great use: , Remove the ORDER BY:
SELECT (@row:=@row+1) AS ROW, ID  
FROM table1 ,(SELECT @row := 0) r   
select *
from 
(
  SELECT (@row:=@row+1) AS ROW, ID  
  FROM table1 ,(SELECT @row := 0) r
) x
order by row
SELECT (@row:=@row+1) AS ROW, ID  
FROM table1, (SELECT @row := 0) r
order by id desc;
ROW | ID
----------
1   | 15
2   | 10
3   | 2
SELECT (@row:=@row+1) AS ROW, ID  
FROM table1 ,(SELECT @row := 0) r   
ORDER BY ID;
ROW | ID
----------
1   | 2
2   | 10
3   | 15
select *
from
(
  SELECT (@row:=@row+1) AS ROW, ID  
  FROM Table1,(SELECT @row := 0) r   
  order by ID desc
) x
JOIN Table2 
  on x.ID = Table2.ID;

Hope that helps MySQL provides this capability via the UUID_SHORT() function.
To see it in action:
SELECT UUID_SHORT(); # then repeat.
