I have to write the query to collect latest added top most 2 videos under each category in a single query.

Note : Single video may belong to one or more category.

Thanks for your help in advance.

select * from video
inner join video.id=videocategory.videoId
group by videoCategoty.categoryId
order by video.addedDate desc
limit 0,2

something like that

Hi Cosai,

Your query is returning only 2 rows, I am in need to 2 rows(latest added) from each category. If it has 3 categories, the query should return 6 videos, 2 videos from each category.

Thanks.
