How to get this output

Hi evrybody
i have a question like this
i need to display the row data like this
If i use this sql
select datediff(yyyy,'01/01/2001','01/01/2004')
i get the output = 4

problem is sometime first parameter will be null
like this
select datediff(yyyy,NULL,'01/01/2004'),'N/A')
in that case my result looks like NULL

But what i need to see is if the result is null then i need to display like this N/A

How to do this task ?

Hey,

You can use the isnull method, so that if a value is null, it will return another value, like 'N/A' in this case. Though I don't know how that could work in a datediff method. Rather, you may want to wrap the isnull around the entire datediff call, so that if it returns null, you can return 'N/A'.

|||Hi i already used isnull
like this way
select isnull(datediff(yyyy,NULL,'01/01/2004'),'N/A')
but it giving me error !

"Conversion failed when converting the varchar value 'N/A' to data type int."

Try changing this:

select isnull(datediff(yyyy,NULL,'01/01/2004'),'N/A')

to

select isnull(convert(varchar(4), datediff(yyyy,NULL,'01/01/2004')),'N/A')
