Format number in string with db2, error "the number of arguments specified for varchar is invalid"

Question

From my db2 I have to take a number, example:

1234.56
234
11:55
12323.88

and format in string:

1,234,56
234
11,55
12323.88

I tried:

VARCHAR_FORMAT(VALUE(CASE WHEN X_Type='1' THEN Y_Type ELSE Y_Type*-1 END,0), '9G999D99', 'de_DE') as money

but

"the number of arguments specified for varchar is invalid"

How can I do it? another?

Answer 1

I'm not quite sure what you are trying to code, but maybe this example will help

SELECT
    VARCHAR_FORMAT(col, CASE WHEN X_Type='1' THEN Y_Type ELSE Y_Type || 'MI'  END, 'de_DE') as money
FROM
    TABLE(VALUES 
       ('1','999G999D99', -4324)
    ,  ('2','999G999D99', -4324)
    ) AS T(X_Type,Y_Type, col)

which returns

MONEY      
-----------
  -4.324,00
  4.324,00-
