What sql statement would be able to get values of a field if the records returned are more than one?

For instance, I know that if only one record is needed to be set in a variable, I could do this:
Code:
declare @var1 varchar(10)
select @var1 = [fieldname] from [tablename] where [conditions]
So @var1 will contain the data.

But how would I do it if I know there will be more than one record returned?
