3 , NA , NA ,20
4 , balu ,NA ,NA
5 , hari ,NA ,30
plese tell me how to write query while achive in above issuse.
This is a little odd given the data you presented. Here are a couple of ways you do it.
select isnull(nullif('', YourColumn), 'NA') as YourColumn,
case when YourColumn IS NULL OR YourColumn = '' then 'NA' else YourColumn end as YourColumn
Here is the problem. The data you posted appears to be ints. You can't mix int and varchar data in the same column unless you cast your numeric data to a varchar. If at all possible I would do this type of formatting in the front end instead of in sql.
