How to return Yes or No in SQL without if/case flows

Question

Apart from the IFs and the CASEs from SQL, is there another way to return a table of "Yes"/"No" (in SQL)?

EDIT: Yes, it's bad practice, and no I can't do so in the application (it's a school project with specific requirements)

Answer 1

The following is bad practice:

You can have a column that has the string values "Yes" and "No" and then just select from that column.

You will then have to maintain this columns values.

A better practice would be:

Have a bit column and then in the selects against that column have a case statement to return string values.

Answer 2

use an inline view to translate 0 to 'No' and and 1 to 'Yes' , though you could just stop at no.

SELECT yesNo.Option
FROM YourTable A
LEFT JOIN (SELECT 1 ID, 'YES' as Option UNION ALL SELECT 0, 'No') YesNo
 on A.Field1 = yesNo.ID

This assumes that 0 is in the results of mytable somewhere.

1. Field1 should be the the column name having 0 or 1 or whatever in it you need to translate
2. yourTable should be just that the table in question (or query)
3. All this does is create an inline view with a list of hard coded translations. Better would be to have a translation table and simply use it.

Answer 3

A good idea would be the use of UNION between two selects, one with 'yes' and one with 'no'. But the above answers are enough. Thanks!
