Solution 1

If the default image is in some other table you can join that table into your query and for example with coalesce function select the default when necessary. For example something like:

SQL

select coalesce (a.simage, b.defaultimagefield) 
from tbstudent a, tablewithdefaultimage b ...

Solution 2

you can have a temporary table with single image value represents empty image then use the following query..

SQL

SELECT (CASE WHEN simage IS NULL THEN (SELECT emptyImage FROM TEMP_TABLE)ELSE simage END),sname from tbStudent

Hope it helps..
