Question

I’m having some problem in using order by in mysql. I have a table called “site” with 3 fields like id,name,rank. This table consists around 1.4m records. when i apply query like,

select name from site limit 50000,10;  

it returns 10 records in 7.45 seconds [checked via terminal]. But when i use order by in the above query like,

select name from site order by id limit 50000,10;  

the query never seems to be complete. Since the id is set as primary key, i thought it doesn’t need another indexing to speedup my query. but i don’t know where is the mistake.

Any help greatly appreciated, Thanks.

Can you try this:

SELECT name 
FROM site 
WHERE id >= ( SELECT id
              FROM site
              ORDER BY id
              LIMIT 50000, 1
            )
ORDER BY id
LIMIT 10 ;
