Hi list,

it is possible to use case with character (1) ?

I am having problems to formate the SQL statement.

I have:

SELECT * FROM test;

 a
---
 A
 B
 C


SELECT a,
       CASE WHEN a='A' THEN 'one'
            WHEN a='B' THEN 'two'
            ELSE 'other'
       END
    FROM test;

 a | case
---+-------
 A | one
 B | two
 C | other

I know from all program languages that case do not apply to noun
sequencialiable (if this word exists) variable (like integers etc).

Any help would be greatfull.

Thanks in advance
Ezequias
