Question

I have a classified_id variable which matches one document in a MySql table.

I am currently fetching the information about that one record like this:

   SELECT * FROM table WHERE table.classified_id = $classified_id

I wonder if there is a faster approach, for example like this:

   SELECT 1 FROM table WHERE table.classified_id = $classified_id

Wont the last one only select 1 record, which is exactly what I need, so that it doesn’t have to scan the entire table but instead stops searching for records after 1 is found?

Or am I dreaming this?

Thanks

You want to use LIMIT:

SELECT * FROM table WHERE table.classified_id = $classified_id LIMIT 1
