efficiency

Hi guys,

I guess no one will have a definative answer to this but considered predictions would be appriciated.

I am in the process of developing a mySQL database for a web application and my question is:

Is it more efficient to make a single query that returns a single row using AJAX

or

To request 100 - 700 rows when the user will likely only ever use the results of two or three?

Really I am asking what is heavier for the server 2-3 requests with one result or 1 request with 100 - 700 results?

Thanks,

Mark
