How to use the case statement in views…

When I try to execute the case statement, it is giving warning message and showing the output, but when I try to save the views it is giving no output column specified errors

Query

Select 
    emp_code, 
    case 
        when emp_name = 'a' then 'Apple' 
        else 'dummy' 
    end as emp_name 
from table1

There is any other option is available instead of case.

Need query help

I don’t think you can name your new “case” computed column the same (emp_name) as a column that already exists in the table – try using some other name!

SELECT
   emp_code, 
   CASE 
       WHEN emp_name = 'a' THEN 'Apple' 
       ELSE 'dummy' 
   END AS new_emp_name
FROM dbo.table1
