Question

i have a table like this:

user  | session
test1 | 11
test1 | 11
test1 | 11
test1 | 21
test1 | 21
test2 | 2
test2 | 2
test3 | 3
test3 | 3
test3 | 32
test3 | 32

i would like to get back that user 1 has 2 sessions, user 2 has 1 sessions, user 3 has 2 sessions
bassically how many the same sessions a user has?

i’ve tryed $sql4 = SELECT user, session , count(*) FROMtablegroup by user, session

and i get the distinct sessions but not the count

any ideas?
thanks

edit:

if i use SELECT user, count(*) FROM users GROUP BY user i get test 1 = 5. it give’s me the total nr or sessions instead of total nr of sessions that are the same. in this case 2

Answer 1

SELECT user, count(DISTINCT session) FROM users GROUP BY user

DISTINCT used to calc only unique sessions
