If you're just returning for display, then just return one column. This is
a mere exercise in re-arranging your quotes.

CASE OrderMethod
WHEN 0 THEN 'Fax, Email'
WHEN 1 THEN 'Telephone'
END

Otherwise, David is right. A case expression can only return a single
value, not a list or variable number of values.

CASE must return a single expression not a value list. Something like this
should do what you want, assuming that Fax and Telephone are columns of
compatible datatypes.

....
ORDER BY
CASE @ordermethod
WHEN 0 THEN fax
WHEN 1 THEN telephone
END, email

If you show how you're using IF now, we can probably show you how to use
CASE instead...

No. IF is a flow-control statement; CASE is an expression. They are
completely different things.

Check Books Online for a good explanation and some great examples of
both IF ... ELSE and CASE.

Best, Hugo
