I have to increase 'no_of_visits' for 1.
Using UPDATE function is easy:
update visits set no_of_visits=no_of_visits+1 where visitor_id=123
but, how it should be (if possible at all) if I want to use REPLACE
I tried something similar
replace into visitors values ($visitor_id, (no_of_visits+1))
but it doesn't work?!?
Of course; the MySQL "REPLACE" command is not meant for that. It is simply the same as
"INSERT" unless the table has a key, also given in the transaction. "UPDATE" is the right
command for this.
