Question

I have a three tables in an application and I need to perform a query which joins all three of them on a regular basis. Chances are that all three of these tables will be updated often.

I’m considering using a view to avoid having to use the verbose join syntax in several places within my code. Would this be a suitable options? I have not used views in a large scale application before and am unsure of the effects they will have on performance (positive or negative).

Any advice would be greatly appreciated.

Thanks.

Answer 1

In MySQL a view is generally executed only when it’s requested, so it’s almost the same like writing the jong query or executing a query on the view, so in my experience you shouldn’t hit any performance problems as long as the join query is fast as well.
