optimization

I was wondering if adding a LIMIT 1 to a query would speed up the processing?

For example...

I have a query that will most of the time return 1 result, but will occasionaly return 10's, 100's or even 1000's of records. But I will only ever want the first record.

Would the limit 1 speed things up or make no difference?

I know I could use GROUP BY to return 1 result but that would just add more computation.

Any thoughts gladly accepted!

Thanks
