I am having trouble with a CASE statement like this.

The All Cars doesn't work.

SELECT
CASE
WHEN CARS.Model LIKE '%Ford%' THEN 'Ford'
WHEN CARS.Model LIKE '%Chev%' THEN 'Chev'
WHEN CARS.Model LIKE '%Buick%' THEN 'Buick'
WHEN CARS.Model LIKE '%' THEN 'All Cars'
END AS 'Models'

the last selection should just be an ELSE;

SELECT
CASE
WHEN CARS.Model LIKE '%Ford%' THEN 'Ford'
WHEN CARS.Model LIKE '%Chev%' THEN 'Chev'
WHEN CARS.Model LIKE '%Buick%' THEN 'Buick'
ELSE 'All Cars'
END AS 'Models'

The ELSE statement is not returning all models

if you want all remaining model as it is then please try this query

SELECT
CASE
WHEN CARS.Model LIKE '%Ford%' THEN 'Ford'
WHEN CARS.Model LIKE '%Chev%' THEN 'Chev'
WHEN CARS.Model LIKE '%Buick%' THEN 'Buick'
ELSE CARS.Model
END AS 'Models'
FROM CARS

Remember: if within a CASE statement the WHEN clause is TRUE, the following WHEN statements and the ELSE statement is not executed anymore.
So if some data in your example contains the value "fictive Buick Chevron" it will return "Chev" and not "Buick". Only when the data doesn't contain either "Ford" nor "Chev" nor "Buick" it will return the "All Cars" value.

I guess I have phrased my question wrong.

What I was wondering is if it is possible to use a CASE statement to return BUICK, CHEV, and then All Models (including BUICK and CHEV)

Yes, you can. In another column:


SELECT CASE
WHEN CARS.Model LIKE '%Ford%' THEN 'Ford'
WHEN CARS.Model LIKE '%Chev%' THEN 'Chev'
WHEN CARS.Model LIKE '%Buick%' THEN 'Buick'
WHEN CARS.Model LIKE '%' THEN 'All Cars'
END AS Models
,CARS.Model
FROM yourtable


or in the same column using union:


SELECT CASE
WHEN CARS.Model LIKE '%Ford%' THEN 'Ford'
WHEN CARS.Model LIKE '%Chev%' THEN 'Chev'
WHEN CARS.Model LIKE '%Buick%' THEN 'Buick'
WHEN CARS.Model LIKE '%' THEN 'All Cars'
END AS Models
FROM yourtable
UNION
SELECT CARS.Model
FROM yourtable



One more thing: do not use single quotes around column name aliases. If you really want to enclose them in something - use square brackets, otherwise you can misread them for literal strings.:

AS 'Models' - bad
AS [Models] - good
