I suggest:
select count(*)
from table your_table_name
group by team
;
The MySQL documentation at www.mysql.com certainly contains good
documentation regarding the "group by" clause within it. However,
it doesn't really provide a motivation for using it... nor should
it. It is documentation regarding how MySQL implements SQL and
RDMS in general, and not a general SQL tutorial or reference.
I suggest you look a bit further afield for this kind of material.
I got started with this stuff back oh 5-6 years ago with "Teach Yourself
Transact-SQL in 21 Days". (I was working with MS SQL Server 6.5 at
the time.) It did a pretty good job at handling this kind of topic
(group by), "having" clause, joins, cross-tab reports, etc. (It also
did views, stored procedures, batch programming... all sorts of stuff
I hope MySQL has one of these days. :-) )
I'm not saying that this is the book that you should get. But if
you want to increase your SQL knowledge, you should look into getting
something.
Cheers,
Richard
