the most recently added entry in `verse_of_the_day_Bible_trivia` for each

The only SELECT is on MAX('timestamp'). There is really nothing to
Group BY in this query.

Also you may not see a difference because your not even using
'History_field' anywhere in your SELECT statement. I am a little surprised
that you didn't receive a error.

Hi.
In a mysql query, it is recommended that "GROUP BY" fields be indexed? Using
EXPLAIN on one of my queries, I noticed no change between having indexed by
GROUP BY field and not indexing it. Any thoughts would be appreciated.
In this example, should `history_field` be indexed...?

Hello,
Let's say I have an app used in car garages. I have two tables:
table cars
id
make
model
table work_done
id
carid
details
work_date
I need to pull out the last work order for each car. This pulls them all:
select c.make, c.model, c.id, wd.details from cars c join work_done wd
on wd.car
.
Is there anything preventing you from palying with the data and manipulating
it on the way into your site? Trying to make the virtual column in to a real
column that could provide the geo reference for future queries.

if you have kind of geo id number you could use that, failing to have that

Well, first of all.. your subject line mentions GROUP BY which is a database
function for telling the query what to use when performing aggregate functions
like sum, count, average, etc type functions.

Can the SUM keyword in SELECT be generalized to strings?
A tipical use for the SUM keyword is:
SELECT column1, SUM(column2)
FROM table
GROUP BY column1
This works only if column2 contains numbers (and SUM is the mathematical
sum).
What about obtain the same behaviour, when column2
