Can someone explain to me why/how this query works
Hi all,
I have the following simple table:
CREATE TABLE data (
id int NOT NULL,
version int NOT NULL,
value int NOT NULL,
PRIMARY KEY (id, version)
)
ENGINE=InnoDB DEFAULT CHARSET=utf8;
What I would like to do is to find all the values for the latest
versions, that is, for every id I
for every id I want exactly one row, namely the row with the maximum
value of version.
SELECT id,MAX(version) FROM data GROUP BY id;

Hi,
Thanks for your quick answer, but unfortunately this query does not
return the value column of the row; and that is the column I am
ultimately interested in (in combination with the id).

Right, if you want the value column you need too, you need a different
query ...
SELECT t1.id, t1.version, t1.value
FROM data t1
LEFT JOIN data t2 ON t1.id=t2.id AND t1.version t2.version
WHERE t2.id IS NULL;

Right, if you want the value column
Wow, neat. I didn't think you could do that without a subquery somewhere.
Learned a cool new trick today. Thanks!

I have a SQL challenge I'm not sure how to solve. But it's so common, I feel
kind of stupid asking this...
I have a 'user' table with 'login_date' which is an auto updated DATETIME
column and a 'created_on' which is a DATETIME (but not updated after the
record is created the first time)
I want
You could add an extra field called last_login_date which you'd set only
once per session - at login time. At login time you'd set this to the
value that exists in login_date. Then use that for comparison against
created_on.
