If you go back over this thread there was a posting (I foget the persons name - sorry) explaining that count(*) is better than count('constant') but count(an_index_not_null_field) is faster again.

I've never personally noticed any noticable difference in my work no matter which method I've chosen though.

I'll pay closer attention though, in the future.
