Hi,
If I want to make a query in a MySQL database, but I need only the number of results that meet the condition, how can I do that?
Another one: if I have two columns with timestamp data, and I want to know the average difference between the two in all records, what is the query then?
Thanks for your help.
Best wishes, Akos
