Multiple Case conditions in where clause

Question

I have a table where there 2 columns. F1 and F2. Now F1 has Id and F2 has score.

F1 Score
1   10
1   20
6   10

now I want to have a where clause where it considers 6 as 1 and adds them with 1

for example when I use when F1=1 it should give

 F1 Score
    1   10
    1   20
    1   10

I have used

WHERE (F1 = CASE WHEN F1 =6 THEN 1 ELSE F1 END )

but not working.

Answer 1

You seem to want:

select (case when f1 = 6 then 1 else f1 end) as new_f1,
       score
from t
order by new_f1;

EDIT:

You changed the question. For filtering, you would simply do:

where f1 in (1, 6)

Answer 2

Try this:

select (case when F1 = 6 then 1 else F1 end) as something, SCORE 
from your_table
