Question

I have a table name BRANDS. I have another table named MODELS. The tables are like this:

BRANDS
BrandID // pk
BrandName

MODELS
ModelID // pk
BrandID // fk
ModelName

Each brand has zero to many brands associated with it. Each model can be associated with only one brand.

My output should look something like this:

Brand             # of Models
Goodyear               5
Chevy                  19
Toyota                 7  

The query I use to get the models looks like this:

SELECT   BrandID, BrandName
FROM     Brands
ORDER BY BrandName

My count query looks like this:

SELECT COUNT(BrandID) AS TotalBrands
FROM Brands
WHERE SiteID = ?

I have a few other things that I need to count also, from other tables.

Can you get me started on how to count the items from the MODELS table?

Thanks!!!

I used all of your answers as hints to help me get what I needed. This is the real query.

        SELECT      S.SiteID,
                    S.SiteName,
                    COUNT(BrandID) AS TotalBrands
        FROM        Sites S
                    LEFT JOIN Brands B
                        ON S.SiteID = B.SiteID
        GROUP BY    S.SiteID, S.SiteName

Answer 1

SELECT Brands.BrandID, COUNT(*)
FROM Brands INNER JOIN Models ON Brands.BrandID=Models.BrandID
GROUP BY Brands.BrandID
