行轉列求和：不加 in 條件，sum的數據會不會準確?

個人習慣寫法，擔憂不加 in 條件 ，統計結果會包含其餘的數據

測試驗證：不加in條件，統計結果正確

create table zy
(
    F01 varchar(4),
    F02 int
)
 
insert into zy
select 'A',10
union all
select 'B',10
union all
select 'C',10
union all
select 'D',10
union all
select 'E',10


select 
sum(case F01 when 'A' then F02 end) A,
