I need to denormalize data in sql query, please help!
With the query
select ref, start_time, end_time, person
from appointments
I get, eg:
REF START_TIME END_TIME PERSON
1234 10:00 11:00 USER1
1234 10:00 11:00 USER2
The users want to see it like this:
REF START_TIME END_TIME PERSON
1234 10:00 11:00 USER1, USER2
How do I do this just in sql?
cheers
Tracey.
