Issue with Select Case

Posted on 2013-06-27

Hi Experts,


select distinct
        CASE WHEN TRIM(Cast(decile as varchar(3))) =''  THEN 'U'
        ELSE Trim(Cast(decile as varchar(3))) END  decile
from Table1
where model_name = 'TopTier'

Note : decile is tinyint of length 3 in table 1

I want this select statement to return 'U' as there are no records for model name :TopTier in table 1.

But this statement is returning 0 records. Please correct this statment.

Thanks ,

SAI

Try this.

;with Tbl1 AS
(
SELECT decile
FROM Table1
WHERE model_name = 'TopTier'
)
select distinct
        CASE WHEN TRIM(Cast(decile as varchar(3))) =''  THEN 'U'
        ELSE Trim(Cast(decile as varchar(3))) END  decile
from Tbl1
union select 'U'
where not exists (select decile from Tbl1)

This should work.
select 'U' where not exists (select decile from Table1 where model_name = 'TopTier')
union
select distinct
        CASE WHEN TRIM(Cast(decile as varchar(3))) =''  THEN 'U'
        ELSE Trim(Cast(decile as varchar(3))) END  decile
from Table1
where model_name = 'TopTier'
