Question

apologize if there is already answer for that, but as a newbie to I’m not able to recognize one.

I have a trouble with outputing data from MySQL.
Imagine a table “visits” in MySQL:

1. name------surname------date------visitTime
2. John        White        20111017  13:00
3. John        White        20111017  17:00
4. John        White        20111017  19:00
5. John        White        20111018  07:00
6. Jack        Black        20111017  09:00
7. Jack        Black        20111018  16:00

I would like to have number of visits sumarized by date and printed out on the php page like this

1. name surname 20111017 20111018 ----> other days
2. John White   3        1
3. Jack Black   1        1

the query I’m using so far is

$query = "select name,surname,count(*) as visitCount
          from visits group by name,surname,date";

thanks a lot

Answer 1

I don’t think you want to do it like that. Like KA_lin said this could get very very ugly as you get more and more different visit days.

A cleaner solution would be to group the data with this query.
“select name, surname, date, count(date)
from visits
group by name, surname, date;“

name surname date visitCount

Jack Black 20111017 1

Jack Black 20111018 1

John White 20111017 3

John White 20111018 1
