HELP!

Let's say I have a table similar to the one below:
ID Car Color
1 BMW silver
2 BMW silver
3 BMW red
4 BMW red
5 BMW red
Is it possible to group BMW, and count the colors in separate fields.
Car Silver Red
BMW 2 3"Chambers" <anonymous@.discussions.microsoft.com> wrote in message

If you have a known set of colours, then try
SELECT Car
, (SELECT COUNT(*)
FROM vehicles AS v
WHERE Colour = 'silver' and v.Car = o.Car)
AS Silver
, (SELECT COUNT(*)
FROM vehicles AS v
WHERE Colour = 'red' and v.Car = o.car)
AS Red
FROM vehicles AS o
GROUP BY Car

in a select as you did, but you took it a step further using V and O. What i
s V and O by the way? Are they virtual fields?

What is V and O by the way? Are they virtual fields?
No, they are just aliases for the tables
FROM vehicles AS v
means that you can then refer to the vehicles table as v
Because we are referring to the vehicles table in the outer and inner SELECT
statements, we have to have give them different aliases so SQL knows which
one we are talking about.
