Re: How to make so I only need to specify the id once..
Hi Martijn, yes of course you're right but SELECT COUNT(s.Id)+ (SELECT COUNT(se.Id) FROM subs_erased se WHERE s.Id=se.Id) FROM subs s WHERE s.Id=1 might work, at least in 4.1.x. I did test it with 4.1.9. /Johan Martijn Tonies wrote: Hi, why not try: SELECT COUNT(s.Id)+COUNT(se.Id) FROM subs s INNER JOIN subs_erased se ON s.Id=se.Id WHERE s.Id=1; /Johan This won't return the same result if there's no entries in "subs_erased" for the ID = 1.

Hi, why not try: SELECT COUNT(s.Id)+COUNT(se.Id) FROM subs s INNER JOIN subs_erased se ON s.Id=se.Id WHERE s.Id=1; /Johan Joppe A wrote: Hello, I have a small problem that is probably easy to fix but it is to advanced for me as a "newbe".
