Is it safe to use count property to get bool value returned, with statements like if([[uiTableView selectedRowIndexes] count])

Is it true?

So, if it is it's unsa

by Ertaz in Databases

I have a link tracking table that has (amongst other fields) track_redirect and track_userid. I would like to output both the total count for a given link, and also the unique count - counting duplicates by the user id. So we can differentiate if someone has clicked the same link 5 times.

I've tried emitting this.track_userid in both the key and values parts but can't get to grips w
