Default select query

Hi,

I have a table with 2 fields:

passport varchar
idNo numeric


I have to display the fields in one column
If idNo is null then I want to show the passport number in the column but if neither passport or idNo are null then I want to show the idNo.

I tried the following select query but it only works if both fields are numeric and i can't change the data type for one of the fields as it will coz huge problems:
select idno,passport,
(case when idno is null then passport else idno end) as sid
from student

How can I make it work?

Thanks

you may want to create a UDF for this

but here is my try:

Code:
SELECT
      isnull(IDNO,'') + isnull(Passport,'')as SID 
FROM Student
ORDER BY IDNO
